Hello, We are running a 500 node network. We utilise three internet gateways each of whitch has a dedicated internal firewall, Smoothall advanced, Watchguard 5 series and i am looking to replace an old cisco box with a cisco asa 5505 model. The maximum users going through this unit would be in the region of 200 via a proxy server or if possible setup the 5505 to act as an http proxy. All I need it to do is act as a firewall and allow these users to access the web for day to day task. A dmz is required and this unit is capable of that as well as basic vpn connectivity. Although designed for small business would it be possible to use the 5505 in this setting? Will it handle the traffic requirements? Money is very tight so spending more than £800 is going to be diffcult. Throughput is around 150mbps which I think is enough but I could be wrong.
