opensshd 2.3.0 (oBSD 2.8) ignores ME!

[Andreas Schuldei]

I have a problem I can not identify.
Two firewalls with OpenBSD 2.8

 sshd version OpenSSH_2.3.0

I do a 

ssh  root at 195.84.181.91 -v
SSH Version OpenSSH_2.3.0, protocol versions 1.5/2.0.
Compiled with SSL (0x0090581f).
debug: Reading configuration data /etc/ssh_config
debug: ssh_connect: getuid 0 geteuid 0 anon 0

debug: Allocated local port 638.
debug: connect: Connection timed out

...


and on the Server side a 
tcpdump -ni rl0  host 195.84.105.112 and port 22
tcpdump: listening on rl0
09:07:00.534120 195.84.181.90.22 > 195.84.105.112.40066: . ack 3776275139 win 32120 <nop,nop,timestamp 831104794 74769850> (DF)

...

nothing else, no reply. 

The firewall rules on the server are 

pass in quick from any to any
pass out quick from any to any

The sshd_config is the default one.

ssh root at localhost works fine.

sshd -d does not show anything (exept the normal waiting..., can not do it
from here!)

The strange thing is: I can log into the box from other IPs by my own. 

Please check for yourself if it reacts to other remote OpenBSD Clients. I can
not, I have only this one which is ignored.
