Your router page looks very convoluted *_*
I would follow what kriegsgott gave you, but instead of making two separate entries, just make use of the port range. For the first box, use 28801, and for the second use 28802. It will forward both.
I have no idea what the rest of what the router is asking for...however, try portforward.com
They have a gigantic database of routers, with step-by-step instructions for forwarding ports for each. I'm sure you'll be able to find yours :)
