Its not possible to add UDP mappings in Form1

Line 192 in Form1.cs is wrong. Solution:
mapper = new Mapping(ptype, localport, publicport);

What steps will reproduce the problem?
1. Connect to a NAT UPnP device
2. Try adding a port forward

The port should be added to the list, but isn't under the mono library.

Suspect part of the code is non-blocking in mono, resulting in no port forward.
