"ip addr list" shows the IP's *ASSIGNED* to the interface, not what's
listening to them. To see your port-forwards, run "net ipfilter
list"...you'll get an output of your ipchains firewall rules, followed by
port-forwarding information.
Also note that ${EXTERN_IP} is your *PRIMARY* IP address, and does not
include any secondary IP's...
It looks like your additional IP is correctly assigned, so to get port
forwarding to work, you simply need to allow packets through the firewall
rules, and setup a port-forward for them. In the examples below, I'm
assuming 64.113.72.219 is your secondary IP, and 64.113.72.222 is your
primary IP...if not, switch the statments below as appropriate...
To allow the packets through the firewall, you need to use the indexed
lists, which allow an extended format that specifies the destination IP:
EXTERN_TCP_PORT0="0/0 www 64.113.72.219"
And to port-forward this port to an internal system, you need to use
INTERN_SERVERS:
INTERN_SERVERS="tcp_64.113.72.219_www_192.168.1.1_www"
