You should also disable sshd in inetd.conf as there's no need to have 2 of them running. Generally speaking if you don't need to have a listen IP designated. That's really only if you want people to be able to ssh in only on a specific IP. If, in my setup, I'd specify an IP like you have, I would no longer be able to ssh from one machine to the other through the internal LAN. I'd have to specifically SSH to the one in the sshd conf. As far as security goes, If you only accept ssh connections on the sshd u installed from the ports on the Local IP, there's no real problem there, as no one should be able to get into your internal LAN. However, as I previously said, the sshd that is included in inetd is still running...
