I have an outward facing server (call it server 2) for GW Webaccess,
Virtual office, NetStorage, etc. It also has iFolder loaded on it,
however iFolder needs to reside on server 1 .. as that's where the
clustered volume lives 99.999 percent of the time.

Will server 2 forward the iFolder requests to server 1? What firewall
changes do I need to make to get iFolder working from the Internet?
