Ok, re wrote 2 cards to start clean.
booted up then updated both units (only doing a 2-node setup until some success to keep it simple)
Went into  rpt.conf on each device and added this node info only. Nothing else like you suggested.
Node 1 = 1000   192.168.10.10
Node 2 = 1001    192.168.10.11
rpt.conf
[NODE]  ;Node 1
1000 = radio@127.0.0.1:4569/1000,NONE
1001 = radio@192.168.10.11:4569/1001,NONE
rpt.conf
[NODE]   ;Node 2
1001 = radio@127.0.0.1:4569/1001,NONE
1000 = radio@192.168.10.10:4569/1000,NONE
Went into Interface tune CLI and tested rx and tx in the menu with no issues. Verified COS signal on rx both nodes.  Toggled PTT and Tone on each node and both TX as they should.
To this point I have never had success with Echo ever working. The only way I’ve been able to get 2-way comms was from using iaxRPT connected to the node. I did not go this far because i didn’t want to touch the iax.conf at all.
So, I assume my audio card is fine to some extent. I’m using URI100’s connected to an HT with a COS modification which seems to be working well.
ran core set verbose 10
ran  rpt cmd 1001 ilink 3 1000    from node 1001 with no error output but no connection unlike before I wiped out and started over.
Same results from node 1000
I’m not moving forward from here as to not “booger” up the configs. Done for now so if you have some recommendations on what to do next, I can get back at it tomorrow.
You stated to not worry about setting up the node yet so i only assumed i had to because running node1000*CLI> rpt cmd 1000 ilink 3 1001  only gave Unknown node number 1000 until i setup the node.
after setting up the node this error went away but still did not connect or give any errors.
What are your suggestions?
