ASA 5505 IPSEC VPN Problem

I have ASA 5505 with ASDM 5.2(2) & ASA 7.2(2).

I configure the IPSEC VPN via the wizard of ASDM and it works.

After a few times, it doesn't work anymore without change. When I log on the ASA and I activate the debug, I don't see any packets.

If I activate the TCP IPSEC on the port 10000, when I made a telnet, I see the packet on the appliance ( debug active ).

Do you have already meet this behaviour ?

Have you a solution or a procedure to reactivate the IPSEC UDP ?

Thank you

Re: ASA 5505 IPSEC VPN Problem

find in attachment the configuration file of the ASA.

The external interface 192.168.2.2 is directly connected to the external where all traffic is allowed to the appliance.

I test the VPN IPSEC L2TP with a Windows client and the pre shared key is configured on both side. But nothing in the debug log.

Do you have a solution ?

Thank you
