We have 3 Linksys BEFSX41 firewall routers that sit between our LAN and the Internet. We have 3 static IP addresses. The WAN side of each router is configured with one. The LAN sides of each router are attached to 3 separate subnets. We have a hetrogenous network of approximately 20 boxes - Lintel, Wintel, and AIX RS6000s running many of the standard services as well as a number of oddball services that eat up a number of ports.. I'm looking for an turnkey replacement for this hodgepodge of a routing/forwarding subsystem. The system must support (in order of priority):
3) DoS protection
4) 8 or more ports *each*of*which* can belong to a separate subnet if desired
6) LAN/LAN, LAN/WAN, WAN/LAN and WAN/WAN routing
7) Cannot be a "build-your-own Linux" box gleaned from a web page at xxx.yy.com/~my/science/project
9) Configurable packet drop/reject/forwarding is a plus
I'm seeking a short list of at least three (3) recommended "boxes" costing no more than $25/port. The first responder to list (3) recommendations that can meet #1-7 will be awarded 125 points. Please provide a short statement that backs up your recommendations.
