We are upgrading our networking devices. We have a 175 employee company; 2612 Perimeter router with access list performing firewall functions; 6 branch offices that use PIX 501 (5) and ASA 5505 (1) to VPN to main office PIX 506e.
We plan to upgrade to a 2800 router. 1. Would the 2800 perimeter router be able to do its routing functions and as well as VPN functions? 2. Would a ASA5510 replacement for the 506e be able to do VPN functions and firewall functions? 3. Any suggestions for a NAC device? Any suggestions for network monitoring tool?
