re-routing ports?

sde · 06-22-2003, 06:55 PM

i need to figure out a way to re-route a port to another port.

there is a service that only runs on port: 8767

i can not change the port which the service runs on .. but i want outsiders to be able to access that service on port: 27009

i'm need to do this out of necessity and for reasons beyond my control .. so please don't ask why =)

is there a way i can do this?

thanks in advance,
sde

this will do what you want(assuming you are using iptables)

Code:

/sbin/iptables -t nat -A PREROUTING -i ppp0 -p tcp --dport 27009 -j DNAT --to 127.0.0.1:8767

edit:
change the ppp0 to whatever interface you are using ofcourse

hmm .. how do i undo that? lol

it doesn't seem to work. i'm trying to get teamspeak ( www.teamspeak.org ) to run on our game server which only has ports 27010 to 27020 open. ( don't ask why lol )

the teamspeak documentation notes this:

Q: What ports does the server use?

A: The TeamSpeak Server uses the following ports:
8767 UDP, for the server itself.
Adjustable in the server.ini: ServerUDPPort=8767
14534 TCP, WebInterface
Adjustablein the server.ini: HTTPServer Port=14534
51234 TCP, TCPQuery port
Adjustable in the server.ini: TCPQueryPort=51234

To get server to work behind firewall, nat, masq you need only to open/forward the server port (in the above case: 8767 UDP).

i'm completely at a loss and have no clue if this can really work or not.
