Cannot connect through SSH on 2nd nic

I got 2 networks: 192.168.0.0/24 for 1G, 192.168.2.0/24 for 10G

I got 2 TrueNAS scale machines, 1 physical, 1 VM.
Machine 1: 192.168.0.100 (1G network), 192.168.2.100 (10G network)
Machine 2: 192.168.0.200 (1G), 192.168.2.200 (10G)

The issue: I cannot ssh from machine-1 to machine-2 using the 10G network. I can ping, and check http, everything works. I can also SSH from to the 2 machines using the 10G network from other machines who are in the 10G network

The only thing that I cannot do: ssh from 192.168.2.100 to 192.168.2.200, and vice versa.

I checked iptable rules, nothing. I checked SSH binding (added, removed) - nothing. There are no firewalls in this 10G network.

Any suggestions?
