Hi,

I have just set up my server as a terminal server on the 120 day evaluation while i investigate licences. I have installed the appliations and all is working well and have overcome the 2 remote access barrier.

My questions is how do i access that server from out side the network? I have a SBS 2003 and two 2003 servers. I have a static IP address that my main SBS users and i can access that from anywhere, but how do i remote onto the third server as there is no IP address?

Could some please help.

thx

I presume you have port 3389 forwarded to the SBS box.  Easiest if you have only ojne external IP address is to change the port RDP listens on and forward external address port 3390 say to port 3390 on the new server.  If your router allows different ports on both sides you could make port 3390 outside come into port 3389 on the Terminal Server box.

It is not necessarily a good idea to open up RDP to the internet.... just so I've said it.  Do it myself but normally to specific external addresses allowed through the firewall.

How are you getting your internet connection in, routed through the SBS with ISA server, or directly with a router on the same subnet?

I am connected to the internet directly on the same subnet. I will have one office in germany (5 people) remoting in, i will also have aprox 3 on road people here in the uk remoting in and 3 people fro Ireland. So i would love to configure the firewall to only allow those people but i dont think its that easy!

What would you suggest is the best course of action. I am about to read the links you have provided. Thank you

If you are happy to open it to the net. and can't get a second public IP then change the ports as above links and forward, say, port 3390 into it.  If you can get another public IP then use that.

Ask if you need any more.

It would appear terminated at your router and if your router supports multiple external IP addresses then you could forward them as:

ipaddress1 port 3389 --> server1 (SBS) port 3389
ipaddress2 port 3389 --> server2 port 3389

Other alternatives are:

ipaddress1 port 3389 --> server1 port 3389
ipaddress1 port 3390 --> server2 port 3389

or

ipaddress1 port 3389 --> server1 port 3389
ipaddress1 port 3390 --> server2 port 3390

The last needs you to change the port rdp is listening on at the server.  The middle one requires a router than can configure a port forward with a different port on the outside and inside.

Hi,

Ok very final thing. I am loking at the links you have provided. I have looked at the registrykey and can change this. I now understand that it looks for port 3389. Both servers have this. I am not quite sure what i have to change. If i change the SBS to a randome number than would the nw server rnning port 3389 be set as a default.

I am not sure which server i have to change the port number on and not sure what to change it too.

Either, whichever ones you want to be on a different port.  One will be
externalip:3389
and the other
externalip:3390

from RDP client externally.

Off for a while now.  Post here if not sure on something and will respond later
