Hello , I'm struggling from some days on a strange issue trying to replicate snapshots from a source system ( TrueNAS-13.0-U5.1 ) that is in a natted network , to a destination system ( TrueNAS-13.0-U5.1 ) that is in a public network accessible from the public ip of the source system.
The replication task ends always with this error:
- I check for MTU issues, but both of the systems are set at 1500 .
- I check trying to connect via terminal from source system ( via SSH ) to the destination system, but also in this case, I was unable to SSH to the destination: after about 30 seconds the connection was "closed by remote host" . I managed to solve this issue setting
Nothing to do for the replication task, instead.
After about 30 seconds of run , it ends reporting error ( the debug log is attached ) .
The strange thing is that I have other replication tasks pointing from different source systems ( both same and different TrueNas Core versions, both natted or public ip networks ) to the same destination, and they work without issues.
I hope someone could help, because this is going over my capabilities.
Thanks
Piero
