Hi chaps, in the interests of mailing one answer, everyone being on the list, I'm only mailing this to the list... Thanks for all the hlepfull comments by the way. Everything becomes clear now as well. I don't see anything specifically related to this in the Nutshell books, but found an example in a Stallion Easy Communications Server - a type of serial router. Basically what Telstra are asking works. Although they are only insisting so that their fault tracing is easier. I can undestand that I guess... If only we had networks without users life would be easier. I also studied the Ascend docs. It has examples there as well. If you can translate them. Anyway, the long and the short of it is that the example below will/does work. However, just as an aside, I have my ppp link configured with it's own address. It's still one of my numbers, but it is not the same number as the frbsd box. The ethernet interface in the box is 5, the ppp 'interface' that talks to everything else is 1. I called it 'gateway' in the DNS tables, and I note with interest that often mail that bounces will be returned via gateway.chalmers.com.au. Nothing seems to refuse it though, same domain after all. The box is a gateway with ip forwarding So logically, I suppose Telstra's method works. It just comes down to being irked because I would have one of their addresses polluting my side of the network connection :-) not to mention being told that that's how it will be - like it or lump it. Does this come under the heading SAPS in the dictionary? (System Administrator Personality Syndrome) Interesting discussion I think. Thanks also to to the couple of people who are running their networks according to the Telstra decreed method. Seemingly without problem. Although they didnt' say I don't think, if they also ran their own IP liscence set, or used only the telstra assigned number(s) cheers Robert W Gerald Hicks wrote: > From: Greg Lehey <grog@lemis.com> > [snips] > > > > The correct answer is that your end of the PPP link should have an > > address in your IP domain. > > > > I don't understand that; He would have an IP address in his > domain on the ethernet interface of his router.
