I have a Linux (RH6) gateway with cable internet on eth0.  eth1 hooks to a hub
and a network of a windows 98 box and another RH6 box.  I can ping both ways
gateway to the windows box and both ways gateway to Linux2 box.  I can telnet
from either box on the network to the gateway.   When I try to telnet from the
gateway to either of the others, I get " trying 192.168.0.2" (or 192.168.0.3)
then "connection refused."

ipchains is "ACCEPT", "ACCEPT", "ACCEPT".

/etc/sysconfig/network,  ifconfig, and the routing table from the gateway box
are below.  Why can I telnet only one way?
