Yes. It is in the [nodes] stanza. Every rpt.conf needs to know where the other nodes are, and vice versa, if they are not registered in AllStar. Even if they are multiple nodes on the same machine (127.0.0.1) they need an entry in [nodes].
There’s a thread with examples here: Nodes connected to each other WITHOUT allstar "server'? - #7 by WQXN966_Jason
