![]() ![]() This next window should be filled in automatically, if it is, just click Next.Give it a Server Name (I just used Remote1 again), and enter the internal IP address of the machine you’re passing the services through to (the internal IP, .x).Change the server type to Other and select Remote1, then click Next.Select Public Server Wizard and click Next.Once your Service Objects are added, click the “Wizards” button in the upper right of the page.Click add, and repeat these steps for Remote2, 65502-65502. In the Window that comes up, give it a name (Remote1 for example), change the Protocol to TCP(6), and where it says port range, type the single first you want to use as both the beginning and end port number (65501- 65501).SCROLL DOWN so that you do not add a group, and click on the Add button under Services.So for this example, the computers are both listening on the default Remote Desktop Port of 3389, but when I’m traveling, I want to be able to connect to Remote1 by using the port number 65501, and I want to connect to the computer Remote2 by using 65502. So not only will we be FORWARDING the traffic, we will ALSO be using Network Address Translation (NAT) to change the port before it leaves the firewall. Rather than go into the registry of each computer and change the listening port, we can do everything we need to do in the firewall. But, let’s say for example you want to change the port you’re using for Remote Desktop, and say you even have multiple computers you want to configure. Remote desktop, for instance, normally listens on port 3389. Port forwarding would take traffic coming in to the modem, and FORWARD it along to a specific host (computer) within the network. I ended up combining a few until I was able to work out a process of my own that seems to work best. There are many guides online that are needlessly complex, and some that are confusing and not helpful at all. When it comes to trying to configure something that should be simple like “PORT FORWARDING” in a more complicated corporate firewall, like Dell’s SonicWall, it can sometimes be a bit difficult.
