STEP SIX

Now, the Remote Security Networks must be defined. This is done in the CONFIG =>SECURITY =>VPN =>REMOTE IP NETWORKS =>ADD NETWORK menu. The IP address and network mask must be defined for all remote devices to be included in the remote network for VPN communication. The Remote Security Gateway IP address (set in step five) must also be given for each network. In the example, the RSG IP address for the network 10.255.255.0 is 9.9.9.1, and the RSG IP address for the network 192.168.0.0 is 20.20.20.1.

STEP SEVEN

The last step is to activate VPN and configure the VPN options. Be aware that after activating VPN on the local network, data sent to the remote network will not be forwarded until VPN is configured and activated on that network too. The VPN Options Menu parameters should be set using the guidelines given below. The options should be defined identically for all Remote Security Gateways in a VPN.
