Hi Ankush,

I believe you can do this by running a different sshd for each unique
port (using ListenAddress, Port) that you wish to allow ssh connections
to, then use the "AllowUsers" configuration property for each respective
sshd to limit the logins on each port to given users. You will need to
modify or duplicate the sshd service script to cater for this, and have
multiple sshd_config files, one for each unique port.

Have a look at /etc/hosts.allow and /etc/hosts.deny for this one. Use of
these files will affect all connections, not just those via ssh.

Cheers, Ben
