Create Site to Site VPN
What Do You Want to Do?
If you want to:
Configure the router as part of a
connecting two routers.
When you configure a VPN network between two
routers, you can control how the remote router is
authenticated, how traffic is encrypted, and what
traffic is encrypted.
Configure a GRE tunnel between your router and
another router.
You may want to configure a GRE tunnel if you need
to connect networks that use different LAN
protocols, or if you need to send routing protocols
over the connection to the remote system.
