The VSAT embedded PEP client is an optional feature enabled by entering a license key. Use of the
VSAT‘s embedded PEP client is subject to the Network Operator/ISP supporting the PEP functionality
using a PEP server on the Hub side. It is possible for the Network Operator/ISP to activate the embedded
client software remotely from the Hub, thus requiring no end-user intervention. Alternatively, an end-user
can receive a license key from the Network Operator/ISP and activate the functionality using the CLI
command sw license as shown in the example below.
Example:
# sw license pep mykeyforenablingpep
The PEP server in the Hub may be installed in two different modes.
1. Re-direct mode
2. Transparent mode
Re-direct mode is the default setting. The Network Operator/ISP should inform you if the Hub PEP server
is installed in transparent instead of re-direct mode.
When operating in re-direct mode, the IP address of the TCP PEP Server in the Hub must be configured
in the VSAT. If the VSAT is authorized to use PEP, this is normally performed remotely by the SatLink
Hub when the VSAT logs on to the network. Alternatively, the VSAT user can locally configure the
server address by means of the CLI command ip pep server <ipaddr> using the PEP Server IP
address provided by the Network Operator/ISP.
To enable the PEP functionality, use the CLI command ip pep enable [<mode>], where <mode>
can assume the values redirect or trans. To verify that the PEP functionality has been enabled, type
ip pep show.
The CLI command sequence to configure and enable the PEP functionality is shown below:
Example:
# sw license pep-tcp mykeyforenablingpep
# ip pep server 10.0.0.10
# ip pep enable redirect
# ip pep show (to verify that the functionality is enabled)
PEP Status : enabled
PEP TCP Mode : Redirect Mode
