I created a rule on my pfsense firewall that manages restricting each IP to a
single telnet per source IP.  I run everything on a single ESXi vmware server.
I have around 25 VMs running on it at the moment, including the BBS vm, BBS
tossing VM, pfsense firewall, and lots of other stuff (including my weather
website and weather station software setup).

If you end up using pfsense, I can get you the details on the setup.  It is not
too difficult to setup using pfsense.
