Adding internal and external addresses
The next step in configuring the VPN is to add the addresses of the VPN clients and the address of the
internal network to the VPN gateway.
You do not have to add addresses for remote clients with dynamic IP addresses.
Example VPN Gateway IP Addresses shows the internal and external addresses required for the VPN
Gateway shown in Example VPN between an internal network and remote clients

• Go to Firewall > Address > Internal .
• Click New to add a new internal address.
• Enter an Address Name, IP Address and NetMask for the internal network.

Adding an IPSec VPN policy
The VPN policy associates the source address of the internal network and the destination address of the VPN
client with the VPN tunnel created for the VPN client. The VPN gateway then starts up the VPN tunnel
whenever it receives packets from the VPN client. Once the VPN tunnel is established, all traffic between the
VPN client and the VPN gateway that is destined for the internal network is routed across the Internet in the
VPN tunnel.
