What would be a good, low-footprint firewall to use that has great remote admin capabilities from a company that understands the needs (licensing, support, etc...) of small- and medium-sized business environments? I'm researching a replacement for ESET's Smart Security Business Edition due to poor support from ESET, continuing issues with the software, and poor firewall configuration control. Looking to primarily replace the firewall module, but totally open to replacing the whole thing. Centralized admin control, like with ESET's remote console, a must. Thanks.
