Hi, i have a problem...

I have at work a possibility to run a counter strike server.
this run on a separate machine (vmware) for security reasons in a second subnet on kerio firewall host.

so were behind the nat...

Now, i have the Server running and visible to the internet.
Players can connect, just in the masterlists the server wont appear.

I googled around and found a hint, that the source port of the server show the masterlist the port on that the server is running.
but in some firewalls the source port get spoofed by the nat.

After a check with ethereal i foud out, that this issue seem to be true. the source port of these packets is some 60xxx. the masterlist server reqest for info, my box send him all info about the server.

but when i contribute to the masterlist i find my server with xxx.xxx.xxx.xxx:60xxx (some 60000 to 64000)
the clients dont show a server that they cant reach.

result: no client from the internet can find/connect from the list in his counterstrike game client.

i tried all settings of source nat to change but nothing helped.
still sourceport from server to nat is 27015, source port from nat to masterlist is 60xxx.

hm.

heeeeeeeeeeeeeeeeeeeelp Surprised Surprised Surprised Surprised Surprised Surprised Surprised

Sry Bumping around...

Noone has an idea?
The Function that i need is described in german cs site.
http://www.counter-strike.de/content/server/ser_b_rout.php#s ol_a
ist called

"Outbound NAT Preset"

Can winroute do the job or no?
Does anybody have expirience with a CS server and masterlist replication?
can i re-/unspoof just that packet for example?

I mean that Function is not bad for security, just for that one Packet it make communications impossible.

By the way, i tried Quake3.
Here masterlist works, just there is the Problem that the same somehow happen to the incoming traffic. So the Quake Server just see the inside lan IP. Internet Users get logged in server as if they were lan users. When i ban one out, i ban in fact the kerio Machine.
What would be then with a webserver behind the NAT?

oki greetz, hope somebody has a hint or idea...
