Hello,  I am looking to bridge my YSFReflector bridge to my friend DMR TG52007.  Not sure what information I need to provide here to get started.

I have YSFReflector up and running and I have DVSwitch server up and running on the side.  Followed some instruction but got confuse at:

in DVSWitch config

Not quite understand and not really what port number or IP to put here.
