RE: EzVPN working in just single way

Hi,

Did you check that you don't have this statement in your running config:

no sysopt connection permit-vpn

Did you also verify if you have 'management-access inside' turned on. Try the following debug and terminal logging to gather more information.

Logging monitor informational
Logging class vpn monitor debug
Term mon

Then connect up and start your pings, any translation or ACLs errors should be picked up from the informational monitor. The class vpn monitor debug should display anything funky about the connection if it exists.

If what you're saying is correct that other machines in on your network can ping VPN hosts, but VPN hosts cannot ping in, it really sounds like 'sysopt connection permit-vpn'.

Let us know what you find.

If I tried the inside IP of the ASA, it appears that the ping passed through
the VPN, I can verify that with show crypto ipsec sa, but if I tried to ping
any on the inside IPs it don't pass through the VPN tunnel.?
I still can't allow ping the inside through the VPN tunnel, if you can give
me more hits..

Do you sysopt connection permit-VPN turned off. If so, you'll need to
explicitly allow your vpnpool access to your internal network.
