More TCPDUMP questions...

Does anybody know how I can monitor the traffice of a router remote to our
network? For example: Let's say I have a network (200.10.10.0) and I
would like to view a router with the ip number of 208.10.10.5. I would
like to see all traffic that is gatewayed (sp?) through that router to
another router, 208.10.10.1 for this example, and from 208.10.10.5 to a
machine (208.10.10.10) local to that router. Confused (I almost am and I
wrote this). I will show it all graphically.

                                                        my machine
                                                             I
                                                             I
                                                    Ethernet I
                    (1) (2) I
208.10.10.10 <---------------> 208.10.10.5 <----------->208.10.10.1
Machine PPP Link (ISDN) Ascend Router Ethernet Cisco Router

I would like to see all the traffic that passes at points 1 and 2. If
this requires multiple instances of tcpdump, that is ok. Please help me
out on this. Thanks in advance.

Cliff
