The PFSEnse SG-2440 Commercial Firewall Appliance is a high end router, firewall and security appliance that can support a small to medium sized office.
We really like it because its the best firewall for VoIP. We have headache free voip with this router. If we have VoIP problems at a site, replacing it with a PFSense router is one of the first things we do.
PFSense uses plugins and there is a plethora of plugins for many complex and abstract network tasks. Need to restrict facebook or make your network child safe? PFSense can do that. Need to report traffic by user? PFsense can do that. Need to access your network remotely with VPN? PFsense can do that. Need to troubleshooting tools for a WAN? PFSense can do that.
This 4 port advanced router allows for dual wan and port based vlanning allowing you to route traffic based on physical port in addition to tagged VLans
