Using a VPN When Synchronizing Through the Internet

It is recommended that every synchronization session occur within the corporate firewall. If your deployment of Siebel CRM must support synchronization through the Internet from outside the firewall, then it is recommended that you use a Virtual Private Network (VPN).

If there is a firewall on the network between the synchronization client and the Siebel Server, or between the VPN server and the Siebel Server, then the port for synchronizing with the Siebel Server must be opened on the firewall, and this port must be a port other than port 80. If a VPN connection is not used, then it is possible that your Internet Service Provider (ISP) or another host on the route might block communications on this particular port.
