I would like to connect ASA 5510 8.0(3) to Microsoft ISA 2006 over IPSEC tunnel, but I have a problem.
When ASA try to estabilish the tunnel i got the log status is: MM_WAIT_MSG2
When ISA try to estabilish the tunnel i got the log status is: MM_WAIT_MSG3
And I monitor the Internet traffic outside of ISA and not got any packets from the CISCO over Internet. NOTHING that CISCO seems to be muted.
From ISA I can go to the ASA because I see the log, but the other side is nothing.
Can be the problem the heavy network traffic? Because I nmap the ISA UDP port 500 and that response only 6.03 sec.
