Protocol [proto] Access to an IPSec connection can be restricted to specific protocols. This can
optionally be configured with the proto parameter. Valid entries are listed in the
following table.
Alternatively, any valid protocol number as assigned by IANA can be entered for the
protocol parameter.
Port [port] If the tcp or udp protocol is selected for the protocol parameter, then the access to
the IPSec connection can be further restricted to a single port number. Many well-
known port numbers can be identified by their port name as well.

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.
