iptables and device aliases

["Dave Warchol" <Warchol@harthosp.org>]

Hello:
         I am new to the list.  I am currently using iptables to
redirect traffic on eth0 for ports 80 and 443,  to ports 8080 and 8443,
respectively.  I have request to set up another DNS name for this server
and to redirect entries coming to port 443 for this new DNS name to port
8444.  I think that one way of doing this would be to define a device
alias, say eth0:1, assign it a new IP address and associate the new DNS
name with that new IP.  I could then use iptables to redirect traffic on
eth0:1, port 443 to port 8444.  I was just wondering if iptables
recognizes/supports device aliases or if there is a better way of
accomplishing the same thing.

Thanks very much,
Dave
