I’ve just started playing with the CC100. I have a simple Modbus TCP application up and running. The problem is when I enable the firewall port 502 is blocked. I can’t see any options for this in WBM. Not being familiar with the firewall system, I’m struggling a bit with setting up via console as well. I’m running firmware 04.06.03. It seems strange that there’s not a standard option for allowing Modbus TCP, or am I missing something?
When the CC100 firewall is activated (via WBM => Security => Firewall…), all unlisted ports are blocked, including the Modbus port (502). To remove this blockage, the relevant/desired port must be specified via an associated “User Filter”, i.e.:

Thank you so much! Not sure why I didn’t spot that option in WBM, I thought I had looked everywhere.
