I've searched thoroughly in an attempt to find a similar question here, but aside from finding information about pfSense (which appears to only support 1 WAN?) I can't find much else...
Our current office setup consists of about 15 Macs, and 20-odd Windows PCs. We are currently all connected to a 50MB Virgin fibre connection, but a suggestion has been made to get a second ~100MB connection and filter traffic through each WAN depending on their IP. Ultimately we would like the 50MB line to be reserved/used by only ~7 Windows PCs, and all other traffic should go through the other WAN. We also have a Windows Exchange server and some NAS drives that we will require all machines to have access to, and we have a Cisco RV016 VPN Router which is supposedly being used as a load balancer(?).
Our reasons for this change are that the 50MB line isn't capable of dealing with the traffic being put through it by all members of staff, but Virgin don't offer a static IP on anything >50MB in our area. A static IP is required by our developers for their line of work.
How would we best implement this? What additional hardware would you suggest we get (if any)?
