How to setup SSH+NETCAT across a firewall?

Hi everyone

So I have setup a replication task on my TrueNAS Core system (V13 - Latest version). PUSH configuration, sending the data over by ssh to the other truenas system. It works AMAZING using the SSH protocol, but how could I setup the SSH+NETCAT? I tried setting it to that and Local but it doesn’t seem to transfer anything. My primary server is on vlan 1 ( and my backup server on vlan 135 ( how could I make it work. (All traffic is allowed between those 2 nodes across the firewall)

Thanks in advance!
