Can I get by with one IP

If you use VNC you can change the port that it runs on, so you can configure your router to go to different machines depending on the incoming port number.

If it is an option, try changing the default port for the RDP listener on the servers. For example, you might have 10 servers, so have 10 different listening ports forwarded, 1 for each server. Not ideal...but may be a viable solution if other options aren't available.

This MS KB has info on changing the default RDP listener port.

You could then RDP to each server based on the port #.

mstsc /v:server1:31001
mstsc /v:server2:31002
mstsc /v:server3:31003
mstsc /v:server4:31004
mstsc /v:server5:31005
mstsc /v:server6:31006
mstsc /v:server7:31007
mstsc /v:server8:31008
mstsc /v:server9:31009
mstsc /v:server10:31010

Nope that didn't work. I change the one server I can get to through RDP to port 3390 and then I tried RDP typed the server ip:3389 to see if I can get to the other server, but it took me to the original server that I changed to 3390.
What am I doing wrong?
Can I setup TS gateway with SBS 2008?

I also tried mstsc /v:ipaddy:3389

Which firewall or NAT device do you use? Did you configure port forwarding? Can you post details of your port forwarding rules?

Ok I added another port forwarding to my .10 address.
10 points to 3389
5 points to 3390
server 5 I modified the registry to port 3390
now I can't even get to either server with RDC
I have tried just the IP
I have tried the IP:3389 or IP:3390
I have tried mstsc /v:IP:3389  and 3390

Just increasing the points because I really want to figure this one out.

You can redirect traffic from port 3390 on your router to 192,168.10.5 3389. Did you restart router after changes?

When testing from outside of your network, use:
telnet IP 3389
and
telnet IP 3390

What happens?

Thanks for your help
