We are going to be setting up a remote access VPN to a Cisco ASA 5505, once connected to the VPN the internet traffic from the client will then go back out to the internet from the ASA (for web browsing), but Is there anyway to force the traffic through an AV server at the head office site before the traffic goes back out to the internet?
If your 3rd party AV server supports WCCP, that would be the solution. The ASA will redirect your clients to the external WCCP device (e.g., Ironport WSA, Bluecoat Proxy SG, etc.) prior to allowing them to access the Internet.
