When defining a designated server you will be prompted for the IP
address of that device. Adding an entry to the designated servers list
allows you to quickly setup a firewall entry without having to figure out
TCP port values.
Next, the LAN firewall is set-up to restrict access to the LAN. The firewall option is set to
“outbound” to have the LAN firewall filter traffic from the IOLINK router.
