I have no idea what should come after #9 in this list. You could go back to port 22 and check.
Your others could be on a different network. But, I haven’t used CFS in years so I don’t know what’s going on with that end.
I know at one point CFS used some sort of masquerading. Shut down the firewall and I’d lose ALL connectivity.

It is possible that #10 is a firewall appliance.
