All Experts,
I have configured remote vpn server on ASA 5510.
All the remote vpn clients are able to login to remote vpn server.
The issue is that only first vpn client can ping to the internal network and the rest of the clients cannot ping even though they are able to login.
Could you please help to find out what's wrong with my configuration?
Please refer to the below configuration.
Thanks.

Hi Craig,
Try enabling NAT-T , you have it disabled, try that and let us know e.g crypto isakmp nat-traversal 20

Hi Gorge,
Thanks for your advice.
I will try that and let you know the update.

Hi Gorge,
I am able to ping from any remote client after enabling crypto isakmp nat-traversal 20.
Thank you so much for your advice.
Hi William,
Thanks for your advice too even though I did not need to add "inspect icmp" under class inspection_default.
Appreciate for your help.
Regards,
Craig

You might also try adding inspect icmp under your class inspection_default policy map.
