[Dxspider-support] Spider Client login - Port 23 revisited

[Bob Nielsen]

I had a strange port 23 experience here. I run spider on a machine
inside my firewall (the firewall box also runs Linux).  I tried
forwarding port 23 on the firewall box to port 7300 on the box running
spider and ran into echo problems.  Forwarding 7300 to the other box
works fine, however.
