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)
+-----+
