After defining the gateways in a VPN, add a packet-filtering rule for this VPN. Add the packet-filtering rule using the Packet Filter tab.
When adding a packet-filtering rule for a VPN, leave the Screen field empty.
Specify SECURE for the packet-filtering action.
Type the name of the VPN in the VPN field.
Use any address in the VPN rules. Only addresses that interact with a VPN Gateway and the address specified in the rule will apply. The simplest rule uses * for the source and destination address. This rule allows encrypted use of the specified service for all addresses in the VPN.
