Trusted Network The Local and Remote Trusted Network parameters describe which terminals have
access to the secure connection at the local and remote peers, respectively. Two
fields must be completed for each peer: Trusted Network Type and Trusted Network
IP. The Trusted Network Type determines which type of value to use for the Trusted
Network IP field.
The following network types are supported.
The Trusted Network IP values are used during the Phase 1 negotiations, and must
comply with the values configured at the remote Security Gateway.
In the example above, it is assumed that all the hosts in the private (sub)networks
communicate via the secure connection. The local and remote networks cover the
complete LAN segments (10.0.0.0/24 and 20.0.0.0/24, respectively).
Protocol In this field you can optionally restrict the IPSec connection to a single protocol.
Valid entries are listed in the following table.
Select any if you do not want to restrict the connection to a specific protocol.
Type IP
Valid network types are: Keyword: Examples:
a single IP address address 10.0.0.15
a single IP subnet subnet 10.0.0.0/24
a contiguous IP address
range
range
10.0.0.5-10.0.0.56
10.0.0.[5-56]
Protocol

If you want to restrict the protocols on your secure VPN link, and you need
multiple protocols, then you define a new connection for every individual
protocol. Separate IPSec tunnels will be established for each protocol.
