Could someone explain SSL VPN and Port Forwarding to me?
I have a recently installed AS 5520 that replaced our old PIX 515. We have a contractor who accesses some devices on our network, and they previously used traditional ipsec vpn (we also had a VPN 3000 Concentrator) to access them.
I've set them up with a login for SSL VPN with links to the devices they need to access, however the application they access (with IE) does not load properly - a problem the contractor says is due to ports 1911 and 3011 being blocked. In the limited reading I've been able to do I understand that unlike ipsec vpn, ssl vpn only allows certain ports through. Do I need to configure port forwarding for these two ports to allow access to this application, and if so what do I need for the "local port" and "remote port"?
