NAT (Network Address Translation) – This will enable NAT over the
VPN tunnel in order to access the Internet.

If the LAN IP network of both VPN routers is the same (e.g.
192.168.10.1 / 255.255.255.0), then leave the NAT option
disabled. Note: It is strongly recommended that the LAN IP
networks on both VPN routers are different.
 If the LAN IP network of both VPN routers is different, then
enable the NAT option.
Based on the example, the client settings will be the following:

GRE (Generic Routing Encapsulation)Tunneling
Site-to-Site GRE Tunnel
Configuration > Security Setting > GRE Tunnel
To configure a Site-to-Site GRE tunnel between two routers:
•
Ensure that your router is connected to the Internet and computers and
devices are able to access the Internet through your router and make note of
the WAN (Internet) IP assigned to both routers under the Status page. See page
59 for checking the status page.
Example:
Router A WAN (Internet) IP Address: 10.10.10. 10
Router B WAN (Internet) IP Address: 10.10.10.

•
Make sure the LAN IP network on each router is different.
Note: Changing the LAN IP address of your router will change the LAN IP
network of your router. See page 39 for changing the LAN IP address.
Example:
Router A LAN IP Settings: 192.168.
10 .1 / 255.255.255.0
Router B LAN IP Settings: 192.168. 100 .1 / 255.255.255.0
