[CentOS] sshd: listen on ip1:port1 and ip2:port2

Hello,

with CentOS 6.2 - is it possible to configure OpenSSH
daemon to listen on different IPs _and_ ports?

I have received a 2nd IP address for my server
and have successfully configured by adding the new
"/etc/sysconfig/network-scripts/ifcfg-eth0:1" file.

I'd like SSHd to keep listening at the_old_ip:22
but also at the_new_ip:443.

The 443 on the_old_ip is already taken by Apache,
so I can't just write "Port 22" + "Port 443" to sshd_config.

Thank you
Alex
