Thanks a lot! :)
Did you create a new question already?

Btw... Could you try the last thing on your linux pc for me? :)

Try "ipchains -L" and "iptables -L" just to make sure there are really no firewall rules set by default.

Interesting... Obviously, somebody or something (RH, which I am not sure about) inserted these rules in there.
Did you try to take off these two lines:

REJECT     tcp  --  anywhere             anywhere           tcp flags:SYN,RST,ACK/SYN reject-with icmp-port-unreachable
REJECT     udp  --  anywhere             anywhere           udp reject-with icmp-port-unreachable

Unfortunately, I am not completely sure what they deny. I will look up the documentation later.
In the mean time, try to take them off. You will loose nothing anyway.
