Hello all,
I currently have the following system:
Modem -> NETGEAR DGN 1000 -> TP-LINK TL-WR340GD -> Computers
And I'm trying to open up port 51234 to allow me to host using Maptools, but I can't find a way to do this.
Netgear is on 192.168.0.1
TP-Link is on 192.168.1.1
Ideally, I'd like to not have to change this.
Thanks in advance.

The Netgear needs to forward port 51235 to the external address of the TP-Link, and then the TP-Link can forward the port to your machine.

How do I do that? I've put in the service, but when I try to add it to firewall rules, and enter 192.168.1.1, it says "IP Address is illegal!"

I assume you are trying the Netgear first? You need to use the EXTERNAL, or WAN, IP address for the TP-Link router, and that would be a 192.168.0.x address.
