I've had this router running NAT and PAT (overload) for just about a year. In the past two weeks in two instances I've had to clear translations in order for one of the five sites connected to this router through a WAN to pass through. I'm using nat for an overlapping network addressing problem.
I have four IP addresses allocated to NAT and overload enabled on this pool. In the affected site I only have about 15 servers that connect to the remote site through NAT.
My IOS on the NAT'd router is 12.2.8YJ. I searched the bug toolkit and did not find any relevant issues.
Any assistance is appreciated. TIA
