I have a ASA5505 with a security plus license that has been 'in-production' for some time but I am experiencing a 'lock-out' of a particular IP address in a DMZ with minimal usage.
This IP address is configured with ACL and NAT to allow:
remote desktop traffic
IIS 7 traffic
I have also limited the number of embromic connections to 1500 due to DOS attacks. The issue I experience is that the 'channel' locks up when using remote desktop or IIS 7 services resulting in all traffic being denied to that IP address (channel). All other IP addresses with similar configuration remain working.
Can anyone suggest what the problem may be and how to go about resolving it?
Thanks (in advance) for your help.
