Hello,
I try to setup a new webserver with IPv6 and IPv4 connection. The IPv4
connection works great. I'm new in IPv6 and got some routing problems. I
called the provider support and he told me how to setup the gateway and the
interface... but for linux and not for OpenBSD. Maybe you can help me to setup
the correct configuration, please?
