Created network on systemA inside my LAN. sysB & sysC inside LAN joined the network. Remote SysD and SysE joined the network.
I do not run any firewall code, but my router and one of the remote systems use port forwarding to access port 22 with a 5-digit port number. This all works 100% among all the zerotier clients outside and inside my LAN except for systemA, which fails to connect to remote zt clients (“No route to host”) 25% of the time and, when connection succeeds, soon drops the connection 100% of the time.
SysB and SysC have 100% connectivity with remote systems SysD & SysE, but systemA cannot connect 25% of the time (“No route to host” errors) to remote SysD or SysE and, when sytemA does connect to a remote system, the connection drops in short order.
I have a simple script that reproduces this problem on systemA and demonstrates 100% connectivity among SysB,C,D and SysE.
All I want is for the system that created my ZT network (systemA) to behave like all the other systems that have joined the network!
