I know there are more issues when using SecureNAT - vs. your basic NAT configs. Sounds like when you issue a request to a server - when it sends back - its coming back to another port/ip - which most proxies/firewalls will consider 'spoofed' - setup a monitor of some type or syslog to watch the traffic - look for anything in your proxy logs, etc... I'd point the finger at a false positive of spoofed packets. This is fixed in how you handle your routing. And I agree - 50% is alot - just makes it hard when its UDP - not having any type of acknowledgement - just raw - so I'd setup a syslog of some sort in your router and watch and track it down that way.

Are you using basic NAT or Secure NAT ?
I'm assuming considering I put nothing in the IOS configuration to the mention of secure, I'm runnning basic NAT.
For the guy who was like "50% isn't nothing"... 50% is alot when you're dealing with time sensitive packets, such as with online gaming. 50% on a router just routing webservers isn't a problem. 50% on a router doing game packets is starting to get high. My ISP looked at my CPU graphs (I mrtg almost everything), and we both came to the conclusion that if I Nat-On-A-Stick (basically routing packets thru a loopback to make it seem external) would kill the CPU.
That's 50% of doing just NAT. Nothing else.
Thanks,
Adam
