ipv6

2025-04-02

Greetings,

I've setup a ipv6 tunnel few days ago and it works good.
But today I decide to delete it and reconfigure it with some different settings. Now I couldn't even ping6 a ipv6 ip.

I've noticed one strange things. If I give ifconfig command I get this output:

sit0 Link encap:IPv6-in-IPv4
inet6 addr: ::XXX.XXX.XXX.XXX/96 Scope:Compat

(where XXX.XXX.XXX.XXX) is my range of personal IP

this is quite different from the one I get before. Can anyone help?
Thank you
