Tribes 2 server behind NAT

[Mike McLean <libolt@libolt.net>]

Hi,

I've got a tribes 2 linux server running behind a NAT gateway using iptables.  
I've forwarded both TCP and UDP on port 28000 to my server as follows:

iptables -t nat -A PREROUTING -i eth0 -p udp --dport 28000 -j DNAT --to 
192.168.4.7:28000
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 28000 -j DNAT --to 
192.168.4.7:28000

When I launch the game on another box on my local network.  I see it in the 
server list with the private ip address 192.168.4.7.  However, I have someone 
outside the network trying to conenct, but my game doesn't show up in the 
server list for them.  So they are unable to connect.

I run tribes to with the following command:

tribesd2 -dedicated

Any help is appreciated,

Mike
