settings according to the Dreamcast Live connection guide. Not sure what else to look for.
Also added the ip to DMZ host, didn't seem to matter. hmmm...
I can create and play in a game without issue however.
EDIT: Im using a dreampi and assumed the dns can be set to 0.0.0.0 (using Planet Web 3) if thats the case then, back to square one. If not, does 46.101.91.123 need to be used to successfully connect?
