'delta' is a Windows machine running SBBS and 'myopia' is a Linux box.  You can
telnet/ftp/ping the Linux box from Windows, & vice versa.  You can 'telgate'
from the Windows box to itself.  But you can't 'telgate' from the Windows box
to the Linux box, even though "regular" telnet works?

Weird!

Is the LinkSys router doing any firewalling between the two boxes?  Or just to
the outside world?  Is all the telnet/telgate action taking place on port 23? 
I don't know if telgate does/can use some alternate port...

Can you see if anything is knocking on the door when you try to telgate to
myopia?  Use a packet sniffer to see if delta is sending the packets and myopia
ignoring them or if delta doesn't even send them in the first place?  What
about name resolution?  Does SBBS use the 'hosts' file or only DNS?  Does IP
address 24.160.244.151 belong to you?  Try a traceroute (don't know Windows
spelling) to myopia and myopia.ujoint.org and see if it is OK.  Try using the
IP address of myopia directly in the telgate command.

I dunno what your problem is, but it is an interesting one.  I dunno if Windows
has anything similar to "/etc/nsswitch.conf".  Are you running a DNS server for
the domain?  Can you add delta and myopia to the DNS config rasther than rely
on the hosts file?
