Ok, I've also forwardet Port 22 now. But now my friend has another problem:
Everytime when he tries 'cvs checkout * -d :ext:address@hidden:2401/
usr/local/cvs', cvs says:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

The RSA host key for my.domain.org has changed,

Someone could be eavesdropping on you right now (man-in-the-
middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
01:ba:7f:43:de:5e:b4:b9:c7:04:4b:3d:83:43:5c:00.
Please contact your system administrator.
Add correct host key in /home/user/.ssh/known_hosts2 to get
rid of this message.
Offending key in /home/user/.ssh/known_hosts2:1
RSA host key for my.domain.org has changed and you have
requested strict checking.
cvs [checkout aborted]: end of file from server (consult above
messages if any)

What can I do?
