Openwrt luci disable ipv6

Also, the default installation of the web interface includes the package luci-proto-ipv6required to configure IPv6 from the luci web interface. If you are making a custom build please note that the packages stated above must be installed to provide the corresponding IPv6 functionality.

Our aim is to follow RFC where possible. Please notify us if you find any standard violations. The following requirements of RFC are currently known not to be met:. The following sections describe the configuration of IPv6 connections to your ISP or an upstream router. Please note that most tunneling mechanisms like 6in4, 6rd and 6to4 may not work behind a NAT -router. For an uplink with native IPv6 -connectivity you can use the following example configuration.

PPP-based protocols - for example pppoe and pppoa - require that option ipv6 is specified in the parent config interface wan section. See WAN interface protocols. Further configuration options, if required, can be given in the config interface wan6 section. Note: In order to successfully send and receive DHCPv6 solicitation and advertisement messages between wan6 and the PPP-based adapter you will need to enable firewall rules for the WAN zone containing these two interfaces:.

Static configuration of the IPv6 uplink is supported as well. The following example demonstrates this. OpenWrt provides a flexible local prefix delegation mechanism. It can be tuned for each downstream-interface individually with 3 parameters which are all optional:. In this case the system will first try to assign a prefix with the same length but different subprefix-ID.

If this fails as well the prefix length is reduced until the assignment can be satisfied. If ip6hint is not set an arbitrary ID will be chosen. If the ip6hint is not suitable for the given ip6assign it will be rounded down to the nearest possible value.

If ip6class is not set then all prefix classes are accepted on this interface. The default class for a prefix is the interface-name e.The result is a bridged LAN no internal subnets that will work fine for home and small networks.

Of course you can achieve this with using the web interface: Once you have configured your wireless network with LUCI you can start configuring your dumb AP.

On switchless devices, simply bridge all ethernet interfaces together, remove the existing WAN interface - if any. If you still need dnsmasq running for something else e.

TFTP server you can do:. Disable odhcpd with uci:. If you would like your AP to receive IPv6 as a host only and not for routing you have to tell dhcp6c not to request prefix deligation. If you do not do this the AP will reject basic IPv6 addresses. If you want to still be able to use ipv6 on the Router itself change the wan6 to lan6 and wan to lan. By default on bridged interfaces on OpenWrt at least tested in On WiFi the slowest modulation available is used for multicast packets so that everyone can hear them.

This can completely use up the WiFi airtime with even fairly light multicast streaming. This will cause the bridge to forward only on bridge ports that have requested to receive the particular multicast group. By disabling legacy User Tools Register Log In. Site Tools Search.

I tried the trunk build of bb, wifi seems much better on my wrn, however I have problems with ipv6. I was not able to ssh to my router, because I got ipv6 adress only in ifconfig eth0, I don't know what ipv6 adress should I ssh to, I don't know a thing about ipv6 and to be honest I don't want to know yet.

What is the correct way to disable ipv6? I don't want it at all, we still have plenty of ipv4 adresses in here, so most isps including mine do not support ipv6, so I don't need it too.

Why should i rembeber adress like a week long, when I can still use those nice ipv4 adresses Is it as simple as that? Or yet another things elsewhere? Question two: How can I compile without ipv6 support to save flash space?

In make menuconfig I've tried to uncheck. I would try to build everything from scratch. This means you will need to issue a make dirclean and then make.

Thank you, I will try it. If i'd settle with leaving it off, what is the best way to do it? At least I can free up some ram memory.

There's new thing like 6relayd, maybe more IPv6 is probably not your problem. There's a bug in trunk right now where dnsmasq doesn't startup in the proper order and won't give out IPv4 address via DHCP.

See here:. If you only got an IPv6 address and not an IPv4 address also then this is your problem. Disabling IPv6 is more trouble than it's worth from a compilation perspective. If you want to disable it, simply stop 6relayd from starting up:. Hi, I'd like to return to this topic. So How can I disable ipv6 dhcp assignment and ipv6 on interfaces?

Even when I delete ipv6 boxes in menuconfig, ipv6 is still there, so I'd like to disable ipv6 on prebuilt image from downloads.

Most people are probably trying to make ipv6 work, but I can't configure it secure and I don't want to bother with it yet, most ISPs don't support it and I don't want it too.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Here is the config I want to archive. Edit: Fund I mistakenly called the file network where it should have been dhcp. Regarding 1. I just tested leaving the wan section as is with the ignore setting set to 1 and I can confirm that works with my setup. Sorry, I was too quick in my last comment.

The 'wan' section cannot be present for my setup to work. If the 'wan' section is gone IPv6 assignments works, but no IPv6 traffic gets through the router. Pinging IPv6 from the router works. I used native IPV6 in my school,and the router get IPV6 address,but no ipv6 address on my phone and laptop wired connected. Finally i installed 6relayd. It is a package abandoned over openwrt JKAbrams does something like bastien-roucaries solution work for you?

I'm not sure I understand what problem decomposing into different VLANs is supposed to solve or how it relates to the fact that I'm unable to use Luci to configure my router into a working configuration, this bug report is meant toward finding a solution to that problem.

To recap: I try to set my network up in the most common sense way I can think of that actually works with my ISP, please let me know if I'm somehow mistaken here as my knowledge of networking is limited. Since IPv6 addresses are globally unique to me it makes sense to have each client have their own so they are addressable therefore the router should let these assignments from my ISP's DHCP through, but since most of the world is still IPv4 the router still needs to be configured for IPv4 NAT. With a default config, this does not work for me, I've failed to find a way to use the Luci interface to archive this configuration, I did however find a way to configure the router manually as documented above that worked until it broke by the update, but I think this is most likely due to an unrelated bug as the config above is rather straight forward and based entirely on the information I could find on the IPv6 guide on openwrt.

You are at risk of giving away your LuCI web credentials to attacker. There are some ways to mitigate this risk.

It's simple. Just make sure that luci-ssl and its dependencies are installed. Unless you have done some workaround such as expanding overlayfs size, it's unpractical. Well, this is a good browser feature. Unless the self signed root CA has been imported to the browser, this warning creeps you out! Why bother with commercial CA when your need is just securing your own router management interface for your own use?

Of course, you can just buy a properly signed certificate for your own openwrt. You can also just import the self-signed root CA used for certificate creation to your browser certificate store.

This is good news for limited-storage devicessince it's not necessary to install additional TLS libraries. Of course, there is disadvantages for this method.

I think the setup complexity is for the first time only. Later, it will be more simple to start the tunnel.

By default uHttpd listens to 0. To prevent Luci web interface from being brute-forced from attackers already in the local network, we are going to edit the uHTTPd config file and change its settings, so it only listens to localhost If you are willing to spend a little effort to setup SSH -tunnel, here is a simple guide for some popular SSH clients.

This guide is just about setting up a local port forwarding to LuCI web interface. This setup will forward all traffic passing through port from You may understand better by viewing this graph. All traffic bypassing through port on local machine will be forwarded to port 80 on the remote machine. That's why this SSH -tunnel setup is called local port forwarding. To establish an SSH tunnel for LuCI web interface access, just add a local port forwarding options to the command line.

Make necessary adjustments if needed hostname, port, identity file, etc. For convenient setup, you may create host profile for this setup. Be sure to make necessary adjustments if needed. After creating the above configuration, the SSH -tunnel can be started by issuing the following command.

To establish SSH -tunnel, you need to perform more steps. Click Add until the port forwarding setup appears on Forwarded ports section. Typically, the shown forwarding setup is L Navigate to Session. Fill root openwrt.

If you have modified your OpenWrt hostname and SSH listen port, you need to adjust the value accordingly. Click Saveso that you don't need to repeat this setup for future use. To start the SSH -tunnel session, click Open. The tunnel will be active as long as the SSH session is active. With this setup, you minimize the risk of LuCI webserver being brute-forced and prevent unauthorized access to LuCI web interface, as long as your SSH setup is secure disabling password and using only public key authentication.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I did not manage to set it up in my router since then. So, they only came once to check if the problem is on their side: they claim it is not and that either my operating systems Windows 10 Pro, Linux Mint Since I am sure to have the IPv6 enabled in all of the mentioned systems, I come to realize that maybe my router is oldplease understand it as no more supported, the model is: TP-Link Archer C5 v1. Is such setting as above even technically correct, I mean I see the gateway as probably local-only address, is that the problem due to which I cannot browse IPv6-only sites?

I have managed to upload OpenWrt Its also worth mentioning what your ISP settings are - I had to find mine on their forums back in the day and the settings varied based on whether you're on cable or fibre. Some local knowledge might be useful here. I have been informed by the ISP, they assign prefixes automatically through DHCPv6, and that no static configuration is possible at this point.

In light of the fact they want an enormous amount of money without any guarantee that their technician would solve the problem in my place, I'm hereby putting one juicy bounty on this question. I will try to edit this question in order for it to be clearer anytime you ask me a new question. I browse the OpenWrt interface each day for 3 days, but maybe just maybe I found something new to me at leastit is called VLANs, and I don't know what is its purpose, so I am posting it:.

Another thing confirmed, I have found on their Facebook page :. The person suggests downgrading to The bug report is absolutely correct, I do not understand why it is not assigned or why it has very low priority, but I was able to get IPv6 address prefix on I don't have internet connection from the After downgrade to The last step should be enabling IPv6 to the clients.

Could anyone explain to me the difference and usefulness of the Stateful and Stateless IPv6 assignment? Maybe security implications including. Heavily cited please, thank you. I mean what is its purpose and usage.

A DHCPv6 service provides the IPv6 address to the client device and both client and server maintain the "state" of that address i. Stateless DHCPv6 is for the auto-configuration by the client device of its IPv6 address and routing based on the router advertisements.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Tried this version today, got an online game with IPv6 support. I can use my IPv6 suffix for the related computer if switched to 'other', but after it is added, luci assign it to ipv4-nat chain. Ready for beta testing IPv6 has permanent local addresses which can be used to statically address an IPv6 host in a local network. With dynamic DNS I would have to get one domain for each host I want to have external inbound connections to, and have each host update its DNS entry on its own.

Instead I can have the router update its external IPv6 address in dynamic DNS and forward the packets based on dport to the appropriate internal hosts, so externally all services appears to be from the same host. Because relay on odhcpd is unstable. Might be related, as SNAT with v6 does not work either, even after installing ip6tables-mod-nat.

I see the DNAT rules for the host in ipv4 tables but not ipv6 tables. Transparent proxy configuration doesn't even have to have a concept of what IP protocol you are running. Has the issue been abandoned since lingering for 2 years? That would question of LuCI as helper in general.

Firewall configuration /etc/config/firewall

I have the same thinking as well - even my scripts which control firewall through cli use UCI, and that for multiple reason:. Skip to content.
