Yes, you do need the ,NONE. But I’m not sure if it will impact stats. Try it and let us know.
I found this rpt.conf document from K5TRA.
Here’s the revenant bit…
PS. While the K5TRA document says to use the [nodes] stanza for nodes “…not registered with allstar link”, it should also be used for public nodes on the same network to prevent problems with hairpin NAT on some routers. The thing to understand about the [nodes] stanza is that it works like the host file on a PC. That is, node number resolution first looks for the node number in the [nodes] stanza. If not found the ext_rptnodes file (or DNS if you node supports it) is searched.
