Interfaces IPsec Tunnels
General
Enter the following:
Name: IPsecTunnel
Local Network: This is the local network that the remote users will
connect to. So in the head office firewall 10.0.1.0/24 will be used and in the
branch office firewall 10.0.2.0/24 will be used.
Remote Network: This is the network that the remote users will connect
from. So in the head office firewall 10.0.2.0/24 will be used and in the
branch office firewall 10.0.1.0/24 will be used.
Remote Endpoint: This is the public ip's of each firewall, where the
tunnels will be terminated. This means that the head office firewall will use
ip branch wan and the branch office firewall will use ip head wan.
Encapsulation Mode: Tunnel
