Not quite sure what are you trying to do with above.  You don't need iptables to
set up an alias.  The ifconfig or ip commands will suffice.

What do you want to achieve with iptables command?  What it will do is that all
packets addressed for 192.168.1.23 that arrive into box (not generated on the
box) on interface eth0 will be sent to 161.31.31.23 (with that IP address as
destination).  Is that what you wanted to do?
