Description

  • IPv6 doesn't work (destroy and recreate tunnel = 3 pings ok, then nothing)
  • NAT rules don't work to redirect stuff to LXC
  • Can't lxc-attach

This is a good opportunity to reboot the system, remove the NetworkManager and test a script to configure network manually.

  • Disable network manager

IPv6

Instead to use linux-route2 (ip), using linux-net-tools (ifconfig) with sit0/sit1 interface names works:

ip tunnel del he-ipv6 
ifconfig sit0 up
ifconfig sit0 inet6 tunnel ::216.66.84.42
ifconfig sit1 up
ifconfig sit1 inet6 add 2001:470:1f12:ce7::2/64
ifconfig sit1 inet6 add 2001:470:1f13:ce7:ca5:cade:fab:1e/64
route -A inet6 add ::/0 dev sit1

No idea why net.ipv4.ip_forward switched back from 1 to 0 at 16:06.

$ sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 0
$ sysctl net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1
