I'm confused about the allowed_clients settings.
snippet from /etc/gnump3d.conf:
allowed_clients = 192.168.1.0/8; 127.0.0.1
with denied_clients commented out should stop everyone who isn't directly on my home network or PC. Instead, I seem to be blocking some folks but not others! As an experiment, with this setup, I get blocked from 126.96.36.199, but I get in without a hitch from 188.8.131.52.
