Hello Joe, I have followed your prev. post. I use RedHat (7.2 upgraded to 7.3) with ipchains. This box handles about 500 - 1000 Meg of NAT (MASQ) traffic a day. If you would like, you can post your rules to me in private and I will have a look at them. Maybe somewhere there is a "loop" somewhere that just hogs all the resources. I have seen this before but it happened because of a very bad WAN link where the router wasn't picking it up but the modems did (stranges I know)
Have you checked "ipchains -L -M -v" ? This will list all the MASQ'ed connections, give it a try and let us know.
