You can do some funky address aliasing with (for example) pf or ipfw, but it gets rather complex. So, the answer is, "No, you don't need multiple IPs, but the setup gets rather complicated if you don't have multiple IPs. As a result, most people who do this will have multiple IPs." -- Bill Moran http://www.potentialtech.com http://people.collaborativefusion.com/~wmoran/
