If a browser is to access our Nodes on a remote LAN over the Internet, port forwarding must
first be set up for the router that controls the remote LAN. The default port numbers pro-
grammed into our Nodes are UDP port 63179 for Node discovery and TCP port 502 for Modbus
TCP. If these ports are blocked by the router or by a firewall, different port values can be entered
into our Nodes. You or your company’s IT department will then also need to set up the remote
router to forward these different port values.
