I have a Netgear FVS318V3 firewall in my office, with access through a cable internet provider. The Netgear box is attached to a WinXP Pro PC in the office. At home I am running the Netgear VPN client software on a Toshiba Laptop. I am able to establish the VPN tunnel from home and ping the Netgear box. I cannot ping or access the office PC. I temporarily disabled all Windows and third party firewalls and still cannot ping the office PC. Any thoughts?
