Probably I posted this into wrong forum, may be here is correct.
Just did switch from Bordermanager 3.6 to ASA 5510 and I noticed that while outside to inside is traffic and connections OK, inside0 to inside0 traffic (I mean, LAN behind firewall) started behave oddly -- connection between LAN machines is very ... random, I mean, I see that some servers is not accessible for a while, then again is OK.
Probably I missed something with ASA conf, but ... what?
One example: I have web server NAT'ed for public access. During this "odd period" I can access it wo any problems from outside, but ... local to local ... can't.
More thanks, Alar.
