Unfortunately I cant say when it started. I also tried many setups that is why 
I dont think its the configuration of my box. I tried booting a live Linux, 
that should rule out wrong configs. 

This is my current knowledge:

- Connecting (to the server) with putty.exe does work.

- Connecting to a friends server (using openssh) at the _same_ network doesnt 
work. That is it waits until connection times out at
debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP

- Connecting from the server (using openssh) to the outside world does work. 

- Changing MTU changes the point were connection aborts.
with MTU set to 1446 it aborts at 
debug1: SSH2_MSG_KEXINIT sent

Wheras with MTU set to 1500 (on both sides), the client gets
debug1: SSH2_MSG_KEXINIT sent
debug1: SSH2_MSG_KEXINIT received
debug1: kex: server->client aes128-cbc hmac-md5 none
debug1: kex: client->server aes128-cbc hmac-md5 none
debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent
debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP

Thanks,
Micha
