Need Help Setting Up Network

post #1 of 6
Thread Starter 
I'll be leaving the US in a few months and I need to set up a network between several computers. So far, I have been able to connect my computer to at least one other computer per network via remote desktop, and I have set a few of the computers internal IP to static. However, I have no success in connecting from an outside network to my server (Patriot Javelin S4).

My understanding is that in order to connect my computer to multiple computers in a single network I will need to port forward, and then translate the ports for each computer. The translation is where I get lost. My router (SmartRG SR300NE) doesn't have an option labeled "translate." I do see Port Triggering but I'm not sure if it has the same function.

Now, for the server, I am completely lost. I tried routing the internal IP of the server to a specific port, and then tried to connect to it from outside the network via the external IP and port (000.000.000.000:00000) but the connection times out. My server has a webUI that I can access from inside the network. I would assume I could access it from outside the network as well.

And that's the story thus far. If I neglected any important information please don't hesitate to ask for it.

I have attached a crude map of all the networks and computers involved in my adventure.

When you say your router doesn't have anything that says "translate", what you should be looking for is NAT, Network Address Translation. What this does is essentially make all your IP's look like one public IP. Anything hits your firewall/router, and if you have port forwarding setup, it will "translate" the internal IPs and send you on your way to your destination port.

So you'd want to setup port forwarding on the router saying:
FROM xxx.xxx.xxx.xxx ON PORT xxxx GOTO _server_ip_add ON PORT xxxx.

In your router you'll need to put new entries in for each service you want to hit from the outside. Use only what you know you'll need, as this opens those address up some. If you have a webgui, maybe it listens on port 8080. To be sure, you'd add 80, 8080, 443 (ssl) etc...

Hope this helps some. I'm typing this while dozing off from Ambien, so I'm basically drunk. drool.gif

Translating IS port forwarding in this case.

There are basically two criteria to meet:

1) Allow external subnets to access your services on the software firewall of the endpoint (if applicable)
2) Port forward external ports to internal hosts.
3) ???
4) Profit

Once you connect to your external IP address (http://www.whatismyip.com) on the particular port you set to forward, the connection will be forwarded to the internal LAN host that you specified.

Here's a screenshot of how I have things configured at the moment. Virtual Server.png 56k .png file


When I initially started messing around with remote desktop I figured I'd just put the same port number for all the fields. I still have no idea of what External Port Start, External Port End, Internal Port Start, and Internal Port End mean. But now that I look at it, Is this simply a matter of changing my Internal Ports to something different (ex. 3390, 3391, etc.) for each computer I want to remote desktop to? It kind of make since when I rationalize it as a request sent to the external ports will then be sent to the internal ports, but I'm still new to this so IDK,

Im confused by your Networks map.


Are all networks'; Florist, Brad, Home etc are on LAN? If yes, then how are the connected to each other. If no, how are they connected to each other?

How is Bug and Server connected to each other?

Bug and Server will be on my LAN when I move to Japan. The other networks, Florist, Brad, and Home are all located in the USA and independent of each other. I want to be able to connect to to each of those three networks separately via Remote Desktop so that I can do troubleshooting problems as they arise.

I'd also like the computers on networks Brad and Home to be able to access my server in Japan.
