Trouble setting up DMZ for Dreampi

[Robfozz]

Hello, I've got my dreampi up and running, however, I cant seem to get the games that require DMZ to work(Alienfront, Planet Ring, etc.). I followed the instructions exactly, I got my Dreamcasts IP from Quake 3, went into my routers DMZ setting and typed it in there. This should be all I need to do, unless I'm misunderstanding the instructions? I still get the same errors in the games I tried. All the non DMZ stuff works just fine, I can play Quake no problem and surf the web without issue. Really not sure what the problem is. I checked and yes, no other devices are using the 98 IP.

Any advice would be helpful.

What ISP, modem, and router do you have?

Lurking here because I've had this issue intermittently with Worms World Party for over 3 years. I can host(at least I recall hosting without issue) but joining hosted games will crash all players on load. I was told then that it was DMZ related but even when directly connecting pi to modem with no other devices on the network, with firewall disabled, same problem.
