Anyone had any luck with getting IPv6 to work with a Vigor120? Currently with Snap and while I can get a v6 address, ping it internally and am able to resolve v6 DNS entires I'm unable to send any useful external traffic over it.

What have you got the Vigor 120 doing? Try operating in RFC1483/2684 bridged mode with VLAN=10.

make sure you've got a legit ip block assigned and not some private default thingy.

It's just bridging PPoA to PPoE, tried setting up vlan10 but it doesn't appear to have made a difference.

Here is my vlan config:

Code lan_ifnames=vlan0 eth1 eth2 eth3 landevs=vlan0 wl0 vlan0hwname=et0 vlan0ports=0 1 2 3 5* vlan10hwname=et0 vlan10ports=4 5 vlan1hwname=et0 vlan1ports=4 5 wan_ifname=vlan10 wan_ifnameX=vlan10 wan_ifnames=vlan10 wl0_vlan_prio_mode=off wl_vlan_prio_mode=off

the vigor120 shouldn't be involved in the ipv6 at all if you're bridging.

Just follow what Lorenceo did in that thread.

On the modem (your Vigor 120):
Set ADSL WAN interface to VPI=0, VCI=110
Enable RFC1483/2684 bridged mode

On the router (whatever you're running Tomato on)
Set WAN interface to PPPoE tagged vlan=10

No need for that "PPPoA to PPPoE" feature on the Vigor when Snap support PPPoE on EUBA-based connections.

I'm using DHCPv6...

What about if you simply use regular bridging on the vigor 120 (with VPI 0 VCI 110), rather than the PPPoA to PPPoE bridge? Though i'd think in theory this shouldn't make a difference due to how encapsulation works, it seems like a 'cleaner' solution to me.

edit: mentioned above already

and you're getting a normal looking ip block, and you can ping your gateway?

Is your ipv6 address something like fe80:xxx? How do providers set the lan interface on routers with the correct IP out of interest? I always do it manually and use SLAAC instead of DHCPv6

FYI i get a 2406:e000:XXXX::/48 block. Unsure if they multiple v6 allocations.

Same/similar range as eXDee.

Tried playing with VPI/VCI and PPoA/PPoE settings as a test and couldn't even get a connection with anything other than 0/100 PPoA.

Tried playing with the RFC1483 settings on the modem and it somehow kept breaking my connection to the modem via tomato every 30 or so seconds needing me to manually reset the rule through telnet.

I've done a factory reset on both tomato and modem to fix the issues and have given up for tonight, might take another look tomorrow.

You should still be able to get v6 from Snap via PPPoA, I believe.

Try putting your Vigor 120 in PPPoA-PPPoE mode. Disable VLAN tagging on the router. Enter username and password in PPPoE settings on the router. If it connects and you get v4, then that part of it is definitely working.

Under IPv6 settings, select DHCPv6 with prefix delegation.
If you can ping v6 hosts from the router, then you have v6 working on the router.

To get it working with your client devices, enable router advertisements. Do not allow advertisements from WAN or LAN.
See if your PCs pick up v6 addresses. Check whether it's working via ipv6.google.com, or some other v6 only website.

Right now, at least on the Toastman Tomato builds, router advertisements are a bit iffy. The daemon defaults to 1500 MTU which breaks some v6 sites, notably Facebook.

If your v6 does not work with the above settings try the following, which I have been using since that thread mentioned earlier:
Set the V6 options to the following:

Select system under tools, or SSH into the router and enter the following commands:

Code nvram set FILE:/etc/radvd.conf="\\A4\\81~~p\\17\\16\\12interface br0\\0A{\\0A IgnoreIfMissing on;\\0A AdvSendAdvert on;\\0A AdvLinkMTU 1488;\\0A MaxRtrAdvInterval 60;\\0A AdvHomeAgentFlag off;\\0A AdvManagedFlag off;\\0A prefix ::/48 \\0A {\\0A AdvOnLink on;\\0A AdvAutonomous on;\\0A };\\0A RDNSS 2406:e000::100 {};\\0A };\\0A" sleep 10 nvram commit reboot

Under Administration, Scheduler enter the following, to be repeated every two minutes:

Code #!/bin/sh if top -b -n 1 | grep -v grep | grep radvd > /dev/null then echo radvd is running. else echo radvd is not running, starting. #start the process radvd fi

The first section writes a radvd.conf file to nvram, since the default one that radvd uses has the MTU set to 1500, which won't work over ADSL. After running it the router will reboot.

The scheduled task is a small script that will check every two minutes whether radvd is running or not. If it is it'll do nothing, if it isn't it'll start it.

Short of recompiling the firmware, I've not been able to get Tomato to recognise the MTU needs to be different for router advertisements, so have been using the above settings for nearly a year. The only problem with it I've found is that if radvd crashes (which it does, every 12 hours or so), if you're moving some v6 traffic at the time it'll stop, and won't come back till you've restarted the radvd daemon.

If you can't get it working with PPPoA-PPPoE mode, as tehyitz suggested, follow the previous thread and see if that works.
As eXDee said, Snap seem to hand out /48's in the 2406:e000:: range. They're dynamic, even if you're on a static v4 IP. I'm not sure whether you can get static v6 from Snap or not.

you could just ask for a static ipv6 subnet and see if they give you one and it means you can have friendlier ip addresses, dns etc.
