I can connect via l2tp and pptp to my server.
But when i try to ping one of my mailservers (ISP's) i.e. "smtp.1und1.com"
ping hangs as long as the connection is held.
Se this, ping 8-17 are not transmitted during l2tp connection:
[erde:~] Wolfram% ping smtp.1und1.com

Partly, i still don't know what to do... :-)
In server admin:
In the "client information" of my vpn config i have set the DNS-server of my
ISP. Might this one not be reachable when tunneling? Removing it doesn't
help.
Do i need a network routing definition? I have none at the moment.
