Application Incomplete - Leading causes?

L3 Networker

So im doing work on our DR site. Two diff setup scenarios are failing; NAT over a VPN and routing from one PA to another and out a VPN. I can see the rule letting the packets out so a session should start for the return trip but .. nothing.

Both scenarios show Application incomplete; what are the leading causes of this? Incomplete handshake? So maybe the other side never returns an ack on the tcp handshake? Return routing does not work?

Any inout would be appreciated as im running out of options.

thanks fo the advice.

I cant see anything on the output thats helps so far

..and there was nothing in the session window, no session at all, so i guess the handshake never completes, i take it we can confirm the handshake never completes.

sessions won't be built if we're dropping packets. global counters should be run consistently/repeatedly w/ hope of determining reason for dropped packets. The last screen shot unfortunately doesn't give you nor us insight.

ok, well, ill try harder to catch something with the counters. If I cant catch anything, ill call in, thanks for the help.

Hopefully those delta counters can give us a clue. Focus on dropped packets via the following:

admin@Phoenix-VM-Lab148> show counter global filter delta yes packet-filter yes severity drop

Global counters:

Elapsed time since last sampling: 3.307 seconds
