PIX Firewall choosing

[o.trofileeva]

I need advice. What type of PIX Firewall is more suitable for the net with Cisco 2600 as a router (now working)? About 300 users.

It really depends on what type, and how much traffic is going to cross the PIX. Also, is there going to be a DMZ? I would think either the 506 or 515, but it is hard to answer without knowing how it is going to be used.
