I assume you are getting a connection to your client behind ISA but it is stopping there.... Configuring your client depends on if and how it was customized. The config may be different for everyone. 1.) Configure your client to use IPSEC through NAT Mode (general tab under properties) 2.) Connect the client to the Altiga box. 3.) Right click the client in the system tray and select status. 4.) Note the NAT port listed. 5.) Launch the ISA management console and create two protocol definitions: Port: 500 Protocol: UDP Direction: SEND Port: <the one you noted> Protocol: UDP Direction: SEND Give that a shot.
