Multiple udp servers on one IP?

Hi all,

Excuse me if this betrays my ignorance..
I have set up a W 2k3 server with three server apps on it - a game, a radius
server and remote desktop.

As I understand it these all use udp, connectionless. They all obviously use
different ports but the same IP address.

Is there any way - as these are connectionless protocols - that I can get
two or even all three to run, each taking the right udp packet?
Or does the first one just gobble up all the packets and that's it....

Sorry for noob question but you gotta start somewhere.

Many thanks.

Hello,

They just use different UDP port, over the same IP.
As they have exclusive access to the UDP port they are listening (binding it
when starting), there isn't any trouble.

Thanks for the reply, but I am using an external static IP address to three
server programs on one machine:

Static IP is of the type 195.38.81.XX

Game on port 27015

Radius on port 1812

Remote Desktop on 3389

It seems that the first port takes all the traffic even when all three
applications are running. And only one application at a time is visible or
accisible on the static IP.
I am using a Mikrotik router to deal with the routing and NAT and it is
possible I have got something wrong.

Any advice much appreciated.

Remote Desktop is TCP not UDP, and would start before your game. So it can't
be guilty.

Can you post somewhere the screenshot of your router's config ? I would bet
it's the guilty one that foward everything to one port.

Hi again and thanks for the help.

I thought (wrongly?) Remote Desktop was RDP but that might expain one thing...

I can't post it tonight but I will try tomorrow..

Many thanks again.

Remote Desktop use RDP (Remote Desktop Protocol)

OK, I have not totally resolved this - BUT as soon as I change to TCP in the
router for remote desktop, it worked fine.

I could even access the remote desktop from my GPRS mobile phone on terminal
services (whether this is a good idea from security is another matter)..

There just remains the radius server to resolve..

Cheers, Bill

Allow both TCP and UDP for radius and RDP.

RDP may use udp for sounds events.

I think I have resolved this.

I had the wrong protocols for the wrong ports - it was my poor routing.
Thanks for the help
