Unanswered Question
Jun 27th, 2007

Hi All,


We have made a LAN to LAN ipsec tunnel between 2 locations over the WAN, and the details are attached.


The tunnel is estalished; one sode i have a cisco VPN concentrator 3000 and the remote location i have a Linux server which is acting like a concentrator.


on the concentrator side when i try to trace the remote location ie. the Linux side lan iam able to reach the vpn concentrator but only the inside interface and then the traffic dies it does not land on the LAN segment.


If somebody can suggest something on this that would a great help.


regards


Mukesh

Hello Mukesh,


When you try to ping the lan side of the linux server, do you see packets getting transmitted through the tunnel. Does the Tx counter increment.


If so, then on the VForce VPN box, do you see the packets getting there?


Is there any kind of sniffer or TCPDUMP that can be done to verify on that side.


You are correct, the trace should be something like what you stated...



Hope this helps.


Thanks

gilbert
