Okay, what I should have said was "I've not added anything to the routing

With alice(cipcb0) and chris's(cipcb1) interface enabled it looks like
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.16.0.2 * 255.255.255.255 UH 0 0 0 cipcb0
172.16.1.2 * 255.255.255.255 UH 0 0 0 cipcb1
192.168.200.0 * 255.255.255.192 U 0 0 0 eth0
default 192.168.200.62 0.0.0.0 UG 0 0 0 eth0
OK...that makes more sense now.....
Let's recap a few things:
1. Can Alice ping Bob and vice-versa?
2. Can Chris ping Bob and vice-versa?
3. Adding a route to 172.16.1.0 on Alice and pinging Chris doesn't work
4. What is the default route on Chris? Chris needs to know how to get to
172.16.0.0 specifically if it's default route is NOT Bob.
The default route is to 0.0.0.0 through his local gateway 192.168.250.190
I've tried adding routes for 172.16.0.0/255.255.0.0 and the win2k client
seems to fail to route packets for 172.16.0.0 down it.
From what I can tell, what needs to happen on Chris is:
route add 126.96.36.199 mask 255.255.255.0 172.16.1.1
For testing purposes it may be worth trying the specific route to Alice:
route add 188.8.131.52 mask 255.255.255.255 172.16.1.1
and then ping Alice from Chris. When pinging, run windump/ethereal and
see which interface the packets are going out CIPE or interface that is
connected to it's local gateway.
Also, I have a vague recollection that Win2k routing has trouble with
networks whose third ip address component was 0 (even though it is
valid). I could be wrong but I have a de-ja-vu about using networks such
as 192.168.0.x (or in your case 172.16.0.x) and trying add routes. Like
I said, only a vague recollection.....not sure of the exact
circumstances so could've been something else causing it.....
Failing this, what's the route table on Chris look like?
