   Further info here....the Contivity Switch is showing that the tunnel is   
   being terminated by my client (behind the DG834G) and a TCPDUMP of the   
   communication to the Contivity switch shows NAT Keepalives being sent by my   
   client to the switch with the switch responding with IPSec traffic closley   
   followed by a "unreachable" error relating to the client. To be descriptive   
   my client sends a whole pile of UDP packets to the switch from a high port   
   value (e.g. 1578) followed by Phase 2 isakmp packet from again a high port   
   (e.g. 1580) to UDP 500 on the switch. The switch responds with two Phase 2   
   isakmp packets dested to the source port (1580) on my client and then   
   quickly follows with a "udp port 1580 unreachable".   
      
   Is anyone able to tell me if this means that my Netgear box is "dropping   
   packets" required for the session to continue. Note that all ports are   
   forwarded by a rule in the Netgear (supposedly).   
      
   I am assuming that my client terminates the link because of the lack of   
   response from the switch.?   
      
   Any help from anyone, suggestions?
