Currently using Novell BorderManager for firewall and proxy services. Would like to switch to a hardware firewall / proxy device. Have a full T-1 connection with multiple IP Addresses. Not sure what device would be best. Would like to be able to do port forwarding, as well as proxy server for web. I see a Sonicwall for under $500, will these do it. I have about 50 users accessing the net. Thanks in advance.
