We are looking into putting a hardware firewall into a data center to protect our rack of servers.
We are using the servers for terminal services and we have 2 x 1GB connections to the Internet.
We have about 50 servers supporting about 250 users which will grow very soon to 500 users.
We plan to purchase 2 hardware firewalls to provide HA.
Do you think the Sonicwall NSA 240 with Total Secure is a good match for this in terms of performance and protection (from spyware, virus etc?) or is there a better purchase? (Maybe a Watchguard X5 or X8?)
