It's possible there might be something "buggy" in the IOS version. I know
we had a lot of problems with a 3640 and the first two IOS's we put on it.
Not this particular problem. In the meantime, maybe try going into
configuration mode and type in "ip nat trans timeout xxxx", the xxxx meaning
seconds. That way, any hung translations will automatically be cleared on
timeout.

Subject: NAT Problems
Hi All,
I am having problems using NAT on my Cisco 3620 router. NAT translations
works fine but for some reason, the cpu utilization on my router starts
increasing to about 91% after a few days. When access to the Internet gets
slow, I also notice that I have lots of dynamic address translation when I
do a "show ip nat stat", over 1000 active translation with dyanmic
translations being the majority and when my router is really slow, around
6000 dynamic translation. When I do a "clear ip nat trans *", the router
returns to normal, cpu utilization also drops to around 10%. Should I have
to do this every so often or am I missing something from my config file.
I am currently running IOS 12.0(5) and have 48MB RAM on my router.
Any hints/tips would be greatly appreciated.
