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
73 for checking the status page.
Example:
Router A WAN (Internet) IP Address:
Router B WAN (Internet) IP Address:
• 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 53 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
