arp problem with VPN

[josh]

I have set up a cisco vpn client(latest)to a test network terminating in a 2611. This all works ok and I can see packets coming off the router onto the destination network. The destination host arps for the sending device (IP of the VPN client which is the address on the Virtual Interface of the router) in order to reply to the packets and gets no arp response.

Please see attached for router config

Any thoughts appreciated (-:

Hello,

since 172.30.0.0/24 is directly connected to E0/0, try moving the client ip pool to a different subnet, e.g:

ip local pool pool1 172.29.0.32

Many Thanks (-:

Although this was not the complete solution, it did point me in the correct direction:

The router required a route back to the VPN network. This cannot be configured to the Virtual Interface but will work if you point to the real interface.

So I changed the pool so that the clients picked up addresses in the 172.30.50.0 /24 subnet and added a route into the vpn router to point to this subnet via its ser0/0 interface - everything burst into life !

All the best
