Re: quick question: mega-region standalone external port
Sounds like you may need to adjust your firewall/port forwarding ports
to allow the additional UDP ports for the other regions to function.
MegaRegions use more then the single port that the one region uses,
for which ports to allow, check the /bin/regions.ini This is just
my guess based on the information that you gave.
Did the same thing once upon a time. If it is a standalone that you don't need to access off the machine then change that to localhost or 127.0.0.1. If you need it on the same subnet then use your IPV4 address of the machine. If you want it on the net at large then it has to be a real externally reachable DNS name like myexample.com.
