Problem with setting up ipv6 and pppoe

paulo_andre · January 20, 2025, 5:40pm

Not sure if it's ppoe related, but... I just managed to get the ppoe credentials from my ISP and now I don't need the ISP router.
IPv4 works great and I have internet just fine, but IPv6 is not working, not even from inside my openwrt router, I can't ping www.google.com -6

I know it has to be a configuration issue, since before it was working, at least from openwrt, can someone help me here?

The interfaces page, on wan shows:
IPv4: 100.xxx.xxx.xxx/32
IPv6: fe80::xxxx:xxxx:xxxx:xxxx/128
IPv6: 2a12:xxxx:xxxx:xxxx::1/64
IPv6: dda1:xxxx:xxxx:xxxx::1/64

My network file has:
config interface 'wan'
option proto 'pppoe'
option device 'eth0.20'
option type 'bridge'
option username 'xxxxxx'
option password 'xxxxxx'
option ipv6 'auto'
option peerdns '0'
list dns '1.1.1.1'
list dns '1.0.0.1'
list dns '8.8.8.8'
list dns '8.8.4.4'
option ip6assign '64'

What happen if you ping an IPv6 address (like Google IPv6?)

paulo_andre · January 20, 2025, 6:05pm

PING www.google.com (2a00:1450:4003:800::2004): 56 data bytes
ping: sendto: Network unreachable

Are you pinging from the router or from a LAN device?

Don't put an ip6assign on a wan interface. That is for lan-like interfaces.

ifstatus wan and ifstatus wan_6 would be useful to see what you have from the ISP.

The ping was from the router. I disabled ip6assign now, still same result.

Is wan_6 member of wan firewall zone?

paulo_andre · January 20, 2025, 9:00pm

it wasn't, but I added now, and the problem still remains.
Also, wan_6 was created automatically, it says "Protocol: Virtual dynamic interface (DHCPv6 client)", I can't really edit it

trendy · January 20, 2025, 9:05pm

Let's have a better look.

Please run the following commands (copy-paste the whole block) and paste the output here, using the "Preformatted text </> " button:

Are you using mwan3 or pbr by any chance?

paulo_andre · January 20, 2025, 9:37pm

mwan3, but... planning to use, already installed, not actively using it.
I want to have a fallback connection using 4G. but first I want to make this work without it.

trendy · January 20, 2025, 9:39pm

You have not configured it properly and it is blackholing your traffic.
service mwa3 stop; service mwan3 disable; reboot and try again.

paulo_andre · January 20, 2025, 9:43pm

you were right... now I can successfully ping ipv6 addresses from the router. Apparently I still don't have ipv6 in the lan clients, but I'll poke around in the settings a bit more

trendy · January 20, 2025, 9:44pm

Remove the master.

Make them server or hybrid.
