Talk:IPv6 tunnel broker setup

I found that the following line would cause problems, reporting "out of space":

   ExecStart=/usr/bin/ip link set he-ipv6 up mtu 1480

I was able to prevent this problem by introducing a short delay in the previous line:

   ExecStart=/usr/bin/ip tunnel add he-ipv6 mode sit remote Server_IPv4_Address local Client_IPv4_Address ttl 255

The version that I use is here:

   ExecStart=/bin/bash -c "/usr/bin/ip tunnel add he-ipv6 mode sit remote Server_IPv4_Address local Client_IPv4_Address ttl 255 && sleep 1"

I'm not sure if there is a better way to do this, but this seems to work.

Firewall rules

It could probably be a useful addition the strictest possible firewall rules on IPv4 level to make sure everything still works on ipv6 level Garo (talk) 23:52, 14 March 2026 (UTC)
