All LAN-to-LAN traffic uses the VPN between the locations. Any remote non-local traffic (email, http, ftp, etc) uses the remote internet cable connection. For compliance reasons, we now have to monitor the remote location's use of internet resources, as well as verify that only our PC's are used for the internet (no laptops). As a first step, could I add a Linux box at both locations and then use Netfilter/iptables to force all remote internet traffic through the existing VPN and out our cable connection? Second, could I eliminate the firewall boxes, and create the VPN using the two Linux boxes. I've searched the archives, but nothing I've found fits. I'd like to know if it can be done and further any wisdom on how to proceed. Thank you for any help...Ed
