In regards to your first comment:
I don't think thats exactly it. I mean, the virtual server port points to an IP, but it is an IP w/in the range of the DHCP pool. When setting a Static IP, I believe I can disable the DHCP (which greys out the IP Pool), but I don't know what that does.
Conversly, I can set what the IP range is of the DHCP pool...but I wasn't sure I should be messing with that.
When I set the static IP, I wasn't sure what to pick - I picked the IP my PC was using before I started using the router...There was also a 'Default Gateway' field. The manual said if I didn't know what this was to leave it blank.
I went to the WAN settings, where I selected Static IP, and there I was able to disable UPnP. It has a buch of other things in there too... Clone MAC address, and 3 different DNS things.
Considering the DMZ route doesn't let me connect to players, Static IP seems to be the only way....but with this router, there seems to be a host of switches I need to flip and other junk and I must be getting it stuff wrong...
