204.191.16.9 would be the gateway to the remote host...B

I'm not sure that I adequately described my situation...

  [Router]---isdn---[Bridge]---ethernet---[Server]---slip---[Remote]
204.191.16.1      204.191.16.253     204.191.16.2 ed0     204.191.16.3

+------Physical Network #1--------------------+-Physical Network #2--+

On each physical network, I have complete connectivity. Between the 
networks, however, there is no connection. Do I have to manually set up 
some kind of gateway between 204.191.16.2 and 204.191.16.9 (ed0-sl0)? 
I've even (through OS/2) explicitly done "route add 204.191.16.2 
204.191.16.9" for the Remote host, and the remote still can't see the 
other network... Setting 204.191.16.2 as the default route gets me 
nowhere (hangs) and setting 204.191.16.9 as the default route lets me do 
whatever I want with the server...
