imho, this is a normal problem for multi-homed boxes. (multi-homed being multiple IP addresses on one or more cards). When a multi-homed box sends something, it defaults to using its primary IP for that interface. This causes all manner of problems, particularly in a multipath environment or otherwise complex/secure setup where things like VPN, ftp, masquerading and even ping can break. One solution in unix-land uses source-routing. I don't know of similar solutions for Windows, except to only use one interface... This issue always makes me wonder if Microsoft really understands networking at all.
