This is the acid test.  If no packets are getting between the units on 
this port, then something is firewalling them.

Can you telnet into the secondary on this port from the primary, and let 
us know what you see when you tcpdump that port on the secondary

If you get a connection, and see no packets, then something is badly 
broken in assumptions about network connectivity.

You shouldn't get a connected message if it didn't connect.  tcpdump 
won't lie (as long as the options are correct).
