That was me.  YES, telnet to the bastion host.  NO, you don't need an
account and password.  You should be running tn-gw on the firewall, not
the telnetd!  The tn-gw accepts you from the inside, if your IP address
has permission to telnet out, and filters your session to the outside
world.  Same with ftp-gw.

I must have been tired ... I entered "from their" instead of "from
there".  And spell-check didn't even catch it.  ;-)  Oh for the Writers
WorkBench (WWB) of yore.

OBTW, where I came from PPL was the Polymorphic Programming Language.
