Section 6.6: Firewall
The mCore’s Firewall give the user the ability to limit inbound connections. This is done
by limiting what ports can be accessed on the mCore. Once the Firewall is enabled, no
incoming connections will be allowed unless you enter a new rule in the Firewall section
to allow the connection to a specific port. For example, Modbus TCP usually runs on
port 502. If the Firewall is enabled, but no rule entered to allow port 502, then the
Modbus TCP communications will not work. The port must be opened on LAN and/or
WAN port, depending which network it is on.
