Integrate ADSelfService Plus with IIS?

Is there a way to integrate ADSelfService Plus with IIS?  Typically we use host headers on all our external sites and I can't find a way to do that natively within ADSSP.  If it is not possible, how can I change the IP address that ADSelfService Plus uses?  I found an old post from 2009 with instructions but they were for an older build and were fairly confusing.  Any ideas?
