I am looking for an inexpensive router firewall solution to implement on a home users network. The user has a cablemodem and I would like to set them up with a vpn from home to the office. I have a PIX 515 in the office I have vpns already running on and have a 1720 router for them to use in their house. Problem is only 1 ethernet port. Any suggestions as to adding additional ethernet ports to a 1700 or using 2514's, etc to place on clients side?
