Re: Need help experts - VPN 5505 and pat

Base on the configuration, the vpn client should be able to ping the internal host.

You might want to check if there is any personal firewall on the internal host that might be blocking inbound ping from different subnet (normally that is the issue).

You can add the following command:

management-access inside

Then try to ping the ASA inside interface from the vpn client. If that works just fine, then you might want to check your internal host itself, or try to see if you can ping any other 192.168.5.x hosts (pls make sure that you disable the personal firewall which normally is the culprit).

Hope that helps.

Thanks for the reply, I will check that, I have turned on the management interface and I can ping that on the network
