quick basic question about NAT/PAT

I have about 30 users behind a 2620 configured for NAT but I'll call it PAT because I'm overloading all the translations to one static IP. My users are periodically experiencing a very slow internet connection. Could this be the problem and if so how do I verify that it is ? HELP!

Re: quick basic question about NAT/PAT

I'd have to say NAT/PAT alone is not your problem. I have 1500 users being PAT'ed the same way, and the CPU doesn't run above 20% at peak. That's not to say you don't have something else going on there, but it's not real likely the PAT issue.

Quick way to tell is to do a "show proc cpu" (or depending on IOS version, a "show proc cpu hist"). That tends to be very enlightening. Of course, you could be running into routing issues related to your PAT scheme too, but I'd tend to look elsewhere first.
