Title: Forward same ports...different computers?
Post by: Geeman on March 22, 2010, 05:39:46 PM

    I want to forward the same set of ports to two different IP addresses on the same network. I can get the first IP address setup correctly but when I set the port forward options for the second different IP the router gives me a message that there is a conflict between the two IP addresses.  What is the correct way to accomplish what I need to do?
Thank You.
Edit: specific error- 'RDP' [TCP:3389] conflicts with 'RDP2'[TCP:3389] on different IP Addresses.

I am presuming that you want the two machines handling this port at different times.  [For example one during the day and the other at night.]  Even with schedules enabled the router may not have this ability.  After playing with the virtual server, setting up a few nicely spaced schedules and in choosing live machines to forward the same port to, I received your exact error.

This possible workaround just occurred to me, haven't tried it but give it a shot:

1.  Keep your same WAN side public port;
2.  But, on the LAN side make the private ports of the machines different.  For example, port 84 the first machine, and port 8080 for the second period.

Now, as long as the schedules don't conflict, things may work .

Thanks Patrick, I ended up doing just that.  The 2 systems needed to have different ports opened for the same service.  Once that was done I was able to correctly forward the ports.

Croket:

If you can hang on over the Easter weekend, I'll do a few screen captures and you'll be able to see exactly what needs to be done.
