Start at Shorewall FAQ 18 (http://www.shorewall.net/FAQ.htm#faq18). That
will lead you to this article:
http://www.shorewall.net/Shorewall_and_Aliased_Interfaces.html. That
will tell you how to use the alias IP address for ALL outgoing traffic
from the LAN. It is a simple task then to restrict that rule to apply
only to TCP port 25.
