Hey Dan,
To get to the COMCfg settings, on the left side menu go to Setup > System > Storage > Tabular > Edit COM cfg
or you can enter:
http://(yourCosysIPaddress)/index.shtm#editstortbledtcom
to get to the same page. There will be a search window at the top where you can Filter the list. Start typing BroadcastForwarder and it will come up. Change it from 0 to 1, don’t forget to hit Enter and then Save. Reboot and it will allow broadcasts, which are probably whaT that HMI is using, so it it’s not wokring over the VPN.
