I assume that the VPN client has a route to the host you ping. But does
the host in your LAN has a route to the client, i.e. does it know where is?

If the IPsec gateway is not your default gateway, you'll have to install
a route on each LAN host for the subnet.

Alternatively you might consider assigning unused addresses from to the clients, statically or using the dhcp plugin.
Then the farp plugin on your IPsec gateway could take care of responding
to ARP responses on behalf of the IPsec clients.

If that all does not help, you should run a network sniffer to see where
your pings gets lost. Also, make sure IP forwarding is enabled on the
IPsec gateway.
