I'm currently unable to set up a v4-in-v6 tunnel on my linux box (Debian) with the gogoc 1.2 client.
Indeed i run into an error with the "authenticated.freenet6.net" server stating that "amsterdam.freenet6.net" does not support the functionnality.
I tried to use the dslite-amsterdam.freenet6.net or v4.freenet6.net instead but the Gogoc client cannot connect to it (Error connecting to port 3653).
On my windows client with server dslite-amsterdam.freenet6.net it works just fine.
Any idea on solving this issue ?
