Apple IP (AppleShare IP) Gateway - Manual (Page 14)

Figure 2 Combining an Apple Internet Router with the Apple IP Gateway lets
you offer gateway services to all Macintosh computers served by the router.
The Apple Internet Router and the Apple IP Gateway software can run on the
same computer, although they do not have to. Putting the two programs on the
same computer is usually the convenient and cost-effective choice. One
machine provides both services; the software is physically located where the
cabling comes together; and there is only one place for something to go
wrong, so errors are easier to find and correct.
