[Openvpn-users] Trying to understand...

I have been watching this list for a while and also read the manual.
Trying to solve this for a month now, but dont understand:

I am using openvpn in the standard configuration with dev=tun, udp on
port 1194.

My server running openvpn is a linux box, running SuSE linux with
SuSEfirewall2 running.

The intention is to remote control clients via tightvnc.

When I shut down my firewall script, everything is running, so it is
obvious that the problem is caused by the firewall.

How can I find out, where exactly my problem is?
I used tcpdump -i tun0 at the server and when I like to get a connection
from my openvpn client to the tightvnc server (the client
behind the openvpn server) the output is as follows: 19:17:47.724969 IP > S 543787865:543787865(0)
win 16384 <mss 1118,nop,nop,sackOK>

Please help me understand, I am not an expert to iptables but I got the
