Not this time, though. I only have a single chat1.dat in /mystic/data but when I attempt to telnet into the board from wan-side it connects and
then immediately kicks me out with "Connection closed by foreign host."
I just ran into an issue that may or not be related. I have a router with
port forwarding going on, so that incoming connections on certain ports get forwarded to the BBS computer, which is behind the router.
When connections are made from behind the router using the BBS computer's internal (LAN) IP address or hostname, the IP address is logged as the connecting machine's internal address. I can't connect twice simultaneously from the same machine because the BBS refuses the second connection as a Duplicate IP.
When connections are made from beyond the router, the IP address that gets logged is the other machine's internet IP address.
However, when I connect to the BBS from inside the LAN using the router's external hostname (the name that's in the internet DNS), the IP address that gets logged is the router's *internal* IP address. Because of this, I can simultaneously connect from as many internal computers as I want as long as I use the BBS's internal IP or hostname, but when I use the external hostname I can only connect from one machine on the whole LAN at a time because of the Duplicate IP rule.
