<h4><a name="faq18"></a>18. Is there any way to use <b>aliased ip addresses</b>
with Shorewall, and maintain separate rulesets for different
IPs?</h4>
<b>Answer: </b>Yes. You simply use the IP address
in your rules (or if you use NAT, use the local IP address in
your rules). <b>Note:</b> The ":n" notation (e.g., eth0:0) is deprecated
and will disappear eventually. Neither iproute (ip and tc)
nor iptables supports that notation so neither does Shorewall.
