Wireguard tunnels keep failing

Absolutely rock solid.  I have four where my hAPac3 is the server end and one where my hAPac3 is the client end.
 

Chuck, our county tunnel server has 22 active Wireguard tunnels, and is very stable.   It's running on an ac2, if that makes any difference.

NAT and Firewall Traversal Persistence

FYI, This is from the wireguard forum.   I've had such issues in the past with Sonicwall firewalls & VPN tunnels dropping when they get too quiet.  I haven't yet tested the nightly builds as I'm looking to get a couple more nodes for the lab.  

[By default, WireGuard tries to be as silent as possible when not being used; it is not a chatty protocol. For the most part, it only transmits data when a peer wishes to send packets. When it's not being asked to send packets, it stops sending packets until it is asked again. In the majority of configurations, this works well. However, when a peer is behind NAT or a firewall, it might wish to be able to receive incoming packets even when it is not sending any packets. Because NAT and stateful firewalls keep track of "connections", if a peer behind NAT or a firewall wishes to receive incoming packets, he must keep the NAT/firewall mapping valid, by periodically sending keepalive packets. This is called persistent keepalives. When this option is enabled, a keepalive packet is sent to the server endpoint once every interval seconds. A sensible interval that works with a wide variety of firewalls is 25 seconds. Setting it to 0 turns the feature off, which is the default, since most users will not need this, and it makes WireGuard slightly more chatty. This feature may be specified by adding the PersistentKeepalive = field to a peer in the configuration file, or setting persistent-keepalive at the command line. If you don't need this feature, don't enable it. But if you're behind NAT or a firewall and you want to receive incoming connections long after network traffic has gone silent, this option will keep the "connection" open in the eyes of NAT.]

I have updated my nodes so I can use wire guard and I am struggling on where /how to put in the client credientals on node "2" to be able to conenct to node "1" that is set up as the wire guard server etc.   Any help would be great.  I must not be seeing something and having a mental block.
