Key facts

Description

umatiGateway is software for connecting OPC Unified Architecture servers with an MQTT broker utilizing JSON messages. The user interface may possibly be publicly accessible with umatiGateway's provided docker-compose file. With this access, the configuration can be viewed and altered. Commit 5d81a3412bc0051754a3095d89a06d6d743f2b16 uses `127.0.0.1:8080:8080` to limit access to the local network. For those who are unable to use this proposed patch, a firewall on Port 8080 may block remote access, but the workaround may not be perfect because Docker may also bypass a firewall by its iptable based rules for port forwarding.
