I have 2 linksys WRT54GL routers that is running tomato firmware. I am using them in a main/repeater configuration using "Access Point + WDS" on both routers. The main router, the one connected to the modem provides the DHCP server function, wan and dhcp is disabled in the repeater router. My network seems to be working as intended as far as providing wifi access to my 5th wheel by use of the repeater.
The issue I am having is with port forwarding. I have radio equipment in the 5th wheel that I remote control using software that requires specific ports to be open. I am able to run the access the radios while using a LAN connection, but not over the internet. However, I can use team viewer to access the laptop in the 5th wheel and control the radios that way.
SO to get to the point, I need to open ports UDC 33550 to 196.168.51 and TCP 50000 to 196.168.1.51.
196.168.1.51 is the static assigned address for the laptop in the 5th wheel.

To recap, all works fine if inside my LAN, in other words, all the software connects and operates the radio rig with issue. Not able to connect from outside the LAN, i.e. using cell for internet connection, but can use teamview using cell connection..

Thanks for any assistance,
Rick

On the primary router, you need to set the port forwarding features for those ports to the specific IP addresses of the computers/devices. As long as your IP address (public IP of your network) doesn't change, you connect to that IP address and it should forward that port request to the specific device.

You can get your public IP by going to http://www.whatismyip.com/

The problem - every time you reboot your modem, your IP address is going to change.

I have been using a product called LogMeInHamachi - it allows up to 5 users to be in a VPN connection. If you setup your laptop with it, and your remote devices with it, you can connect to the laptop via RDP and then use the laptop to control the radio equipment. This service is 100% free....unless you need more than 5 computers in the VPN.
