Need help setting up remote access to my peer-to-peer network

Ok but how do I do it for all 3 PCs.

You will have to forward a different outside for each system if you are wanting more than one and you only have 1 ip address.  If you have multiple external ip addresses you will be able to do the same port on different ip addresses.

I don't understand your last comment.  I do only have 1 ip address and I need to be able to provide remote access to 3 different pcs.

So on your router you would have to forward traffic from three different ports.  

outside_ip:3389 system_1:3389
outside_ip:3390 system_2:3389
outside_ip:3391 system_3:3389

This is called port forwarding, on the client side outside the netork they will need to connect to different ports on the outside IP address depending on what system they are going to.

So if I understand this correctly this is what I need to do:

On each PC turn on Remote Desktop.   Assuming my outside ip is 123.12.1.1 and the PC IP addresses are 192.168.1.30, 192.168.1.31, 192.168.1.32, I would setup the router like this:

I would login to the router and go to the Firewall Settings page and select Port Forwarding.  I will click Add to add a new port forwarding rule.

Since remote access isn't a rule already defined, I will click on Create to create a new rule.

FOr this rule, I will call it Remote Access and select port forwarding.  Under protocol, I will use tcp.  What am I entering for the Global Port Start , Global Port End,  and Base Host Port?  What do I put for Direction and Port Direction?

Do I use 3389 as the Global Port Start, 3391 as the Global Port End and 3389 as the Base Host Port?

Once the rule is defined, I will choose the rule, select Host and choose the first PC's IP Address.  Now if I repeat the steps for the other PCs how is it going to know which PC is assigned to port 3389, 3390, and 3391.

Do I need to setup a rule for each PC and set the Global Port Start, End and Base Host ports to be 3389, 3389, 3389 for PC 1, 3390, 3391, 3392 for PC 2 and 3391, 3391, 3391 for PC 3?

When I want to Remotely Connect to PC 1 I would enter 123.12.1.1:3389 as the IP address in the Remote Desktop Connection box.  I would enter 123.12.1.1:3390 for PC 2 and 123.12.1.1:3391 for PC 3.

Does this sound right?  I don't have access to the router right now but want to have some idea of what to do when I get to the office to set this up.

OK.  I set the router for Port Forwarding on port 3389.  I assinged PC 1 to the port.  Using another PC, I open Remote Desktop Connection, entered 123.12.1.1 (my outside IP address) and the user name for the computer that I would like to access.  When I click on connect I get:

This computer can't connect to the remote computer.

That is the only error I get.  Looking at the error logs on the router I don't see anything that indicates why I can't connect to the remote computer.  I made sure the Remote Desktop checkbox is checked.  When I used www.canyouseeme.org to check the status of the port it said I can see your service on 123.12.1.1 on port (3389). Your ISP is not blocking port 3389.

Any thoughts on what I should do next?

I would ask to start at the beginning and if you had followed all these steps to allow for RDP?  For instance, some users forget about the Firewall..    (also is there a built in firewall running on that Westell?_

Also, did I see you comment that there are no users with a PASSWORD?  If so, you need to password protect the account before you log in with any RDP session..

I agree Rindi..  I even noticed that Logmein has ported their remote desktop application over to the IPhone, which I am looking forward to trying..
