VPN > IPSec Tunnel
This page provides VPN IPSec Tunnel configuration.
IPSec tunnels define what networks are connected at each end of the link. The actual connection to the
remote end-point used for a given tunnel is configured separately in the IPSec connection tab (this is because
multiple tunnels may use the same connection).
