How many users could I expect to NAT on an RB532?

I have about 96 dialup lines (2 pm3) behind the rb532 now, meaning upto 96 simultaneous users. default settings regarding connection tracking and so forth.

How many NAT users have people had succesfully, if you’ve gone past 96?

I think you would hit the CPU / bandwidth limitation before you hit the nat / connection table limit. A rb532 should handle the nat no problem … 96 users at 56k is about 4-5mbps right?
