This seems like an easy problem to solve with a magic button somewhere?, but I probably don't know the correct term to find it after hours of searching. I have a computer running ignition that sits on the OT and IT network via hardwire and wireless connection; with mobile robots also using the IT network for now. - The mobile robots need to use OPC server, but I can't get access via the wifi connection - I can ping the mobile robots from the ignition computer, and access their internal web servers. - I can't use Ignition Designer via the IT connection;_( I don't think the clients can open via the IT network either, but that was a 5 minute test)_ OT is set as 192.168.10.201, and IT is the fixed address in 192.168.128.190. All the settings I've found in the gateway are either localhost, hostname, or 192.168.10.201. ---
