What do you use for a firewall? We are a small office situation with one remote location and are considering Untangle. I really like that they offer everything in one package without having to buy multiple machines like what I've seen with bigger players, but I want to hear from some people actually using them. Anyone tried Untangle? Pros/cons or feedback welcome. Btw, we aren't interested in anything but a paid solution; my boss wants a support contract and a proven track record, so no free stuff suggestions. Thanks!
