If anyone knows >where I could read more about this could you please post. Maybe a FAQ or >RFC??? Thanks Correct. One system can have more than one IP address assigned to it, but it is utterly WRONG to have more than one machine with the same MAC or IP address. That Linux would allow this is no suprise to me :-) Perhaps he's talking about "IP Masquerade" where a Linux box can "hide" several machines behind it, using it's IP address for connections to/from those machines? Handy for cheap users whose ISP won't provide them with additional addresses. -- David Richards Ripco, since Nineteen-Eighty-Three My opinions are my own, Public Access in Chicago But they are available for rental Shell/SLIP/PPP/UUCP/ISDN/Leased dr@ripco.com (312) 665-0065 !Free Usenet/E-Mail!
