I have exactly the same problem only this is with a Micom terminal server 
(the InstaGate1500).  I dial up from home to a modem at work through the
terminal server, and then connect to a Sun.  I tried seting up similar 
settings in the Micom InstaGate1500, but to no avail.  I must be missing
something.  Does anyone have a Micom specific solution to this problem?
Thanks.
