Hello, first post so please tell me if I missed any detail
My WAN (Zen UK) connection supports IPv6 and is configured and working correctly. I also have an L2TP tunnel (from AAISP) which I route some of my traffic through. This should also support IPv6, but it only rarely gets an IPv6 address.
On starting OpenWRT I get IPv4&6 addresses from Zen and just an IPv4 address from AAISP. At this point if I ping google ping6 -O 2001:4860:4860::8888
from a machine in my network I get replies.
If I run /etc/init.d/network restart
and wait for eveything to reconnect, I still get IPv4&6 from Zen and IPv4 from AAISP, but I also sometimes get an IPv6 from them too. Regardless of whether I get IPv6 from AAISP, my ping to google stops working, until I reboot OpenWRT.
I use PBR to direct traffic to particular interfaces. I also have 2 VPN connections configured, which again PBR routes traffic from specific subnets to these VPNs.
I guess I've configured something wrong here, but I can't work out what! I'd like to get IPv6 working with AAISP. I'll past configs below - any help will be appreciated
