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 ?
