[c-nsp] 2821 NAT Limitations

[Dan Letkeman]

Hi,

Wondering if anyone has some experience with the NAT limitations on a
2821 router?  I have about 1500 users, which about half of them are on
the internet at one time, but we have a proxy web filter appliance
that all of the clients connect to that does a website lookup, and
check before it lets the client access the page, so it creates a
separate entry for every page requested.  This doubles the NAT entries
in the router.

Would 40,000 - 60,000 NAT translation entries be too much for a 2821?
It's not doing much else except NAT and a couple of route-maps.

If so would device would be recommended that could handle this amount
of translations?

Thanks,
Dan.
