I've a few questions (sorry). Should I be able to delete the default network that is setup during install? Each time I try I get an error "Can't access comms network". Each node I setup also joins this default network, even though I didn't want it too. I setup a very simple network, Netmaker server as ingress server, a spare Pi as a Node & egress server onto my LAN. I then added 3 ext clients. Setup one of these on my iPhone using the Wireguard client. I can see in the phones config allowed IP's are the Netmaker network & LAN IP. But I am unable to ping anything on the LAN. What am I missing?
