Step 1: Configure Both Routers for Internet Connectivity
This configuration example assumes the routers are already configured to connect to
the Internet. The configuration uses PPP for the link protocol and has IP routing only.
Branch Office Configuration:
This router has an IP address of 10.0.0.1 on the LAN and 200.10.10.5 on the WAN.
NAT is on and it tunnels to another network (10.2.0.0). It is set as an L2TP Server and
Client -- it can place a tunnel call to its peer or receive a call from a peer. The IP
address of the peer tunnel device is 200.5.5.10.
NOTE:
You cannot ping the tunnel endpoint, only the LAN behind it.
The eth ip addr 10.0.0.1 255.255.255.0 command sets the Ethernet address of the
branch office router. You may not need to change this setting unless both LAN
subnets of the VPN are identical. Each LAN of a VPN solution must be a unique
subnet.
Corporate Configuration:
This router has an IP address of 10.2.0.1 on the LAN and 200.5.5.10 on the WAN.
NAT is on and it tunnels to another network (10.0.0.0). This device is set as an L2TP
Server and Client. It can receive a tunnel call from its peer or place a call to a peer.
The IP address of the peer tunnel device is 200.10.10.5
