104 • SMP Gateway User Manual
To disconnect from the VPN:
From SMP Manager’s Gateway menu, click Disconnect VPN.
13.7 Configuring the Firewall
In the System branch of the left pane in SMP Config, you will find the Firewall branch. This
firewall is protecting the SMP Gateway and consequently the IEDs it connects to. The following
section describes how to configure the firewall, as well as the various options that are offered to
you with the firewall.
Note: Before enabling the firewall, make sure you can use VPN connections through
your corporate network; otherwise, you will lose all communications with the
SMP Gateway, since all but the VPN port will be closed.
13.7.1 Creating the Firewall in SMP Config
The first step is the creation of a firewall instance under the firewall branch:
From SMP Config, under the System branch, click Firewall.
Under Name, type a name for your firewall. A pencil will appear on the textbox left side.
Click Firewall again, you will see a ‘+’ sign appear beside the Firewall branch in the tree
view. Expand the Firewall branch, and the branch of the instance you just created. You will
see two new branches: General and Rules. The parameters they contain are described in the
next sections.
