In the diagram below, from B I can ping all interfaces on A and C.
From C I can only ping B's 10.1.1.9 interface. Given the routing
tables below, is anybody able to tell me where my problem lies?


+-----+
| A | (ADSL modem, NAT enabled, 10.1.1.3 to 10.1.1.32
+-----+ available)
| 10.1.1.1
|
| 10.1.1.3
+-----+
| B | (Win 2k Prof + SP4, IP forwarding enabled
+-----+ in registry, RRAS service running)
| 10.1.1.9
|
| 10.1.1.14
+-----+
| C | (Win 2k Prof + SP4)
+-----+

Thanks Phillip. I noticed the link regarding configuration of RRAS
refers to Windows 2000 Server, I hope that does not mean that routing
is not available under Windows 2000 Professional...

"C" probably doesn't have 10.1.1.9 as the Default Gateway (or have a Static
route).
or
"A" probably doesn't have 10.1.1.3 as the Default Gateway (or have a Static
route).
or
Both of the above...
...and I am assuming by this that RRAS is functioning properly.

2000Pro doesn't have RRAS. I suppose you could hack and chop you way
through it with Pro, but I don't know the steps.
