I need to configure internet based synchronization of ACT 2012. The current server, where the ACT Synchronization service is on a Win 2008R2 (SBS 2011) server, Workstation is Win7. The router currently installed is a Linksys WRT54G router. I have used Cisco VPN's in the past. I want to secure this connection instead of using normal port forwarding from the outside.
Is this possible with this setup. The site does not really want to install a more advanced Cisco appliance that provides a firewall.
How to you accomplish this setup. I have seen some posts on this, but it is not entirely clear.
