According to the devs of this software there is no such option to specify the outbound IP. Can I create an ipfw rule that will reroute/rewrite requests from one of these secondary IP into my main IP? This will help make setting up firewalls on machines that receive this traffic more predictable... Is there a name for what I want to do so that I can Google this sort of thing in the future? -- Joe Auty, NetMusician NetMusician helps musicians, bands and artists create beautiful, professional, custom designed, career-essential websites that are easy to maintain and to integrate with popular social networks. www.netmusician.org joe@netmusician.org
