The problem is that I don't have static IPs. all the machines on my internal net need to grab their IP information over a DHCP server on the other side of the ADSL modem. If I go with an IP router solution i'll have to go with NATd/IP Masq which means no connections incoming from the outside world. I believe when A sends to B an Ethernet packet is sent which contains the MAC addresses, and this is "below" the level of IP networking. I want to analyse that packet and not pass it on to the modem based on that criteria. Other than that, the diagram below is what I had in mind. --- Troy Compton wrote: Andrew: I can't respond to question #1 as I have no experience with Linux, but as for question #2 perhaps you could get by with something like this: A (WinNT) | ADSL --- FreeBSD --- HUB --- B (Win95) | C (whatever) With this scenario you would be using BSD as an IP router. This would block internal traffic from hitting the ADSL at all which, I think, is what you were trying to get accomplished. This takes one PC with two NIC's and a couple of hours. If this comes close to what you want I can give you some more info. I'm using a similar setup at my place with ISDN in place of ADSL. Troy ( BTW Troy : sorry for emailing this to you twice. The first one didn't go back to the list and had typos! oops. ) === "Binaries may die but source code lives forever" -- Unknown SkyHawk Andrew Fremantle starslab@yahoo.com _________________________________________________________ Do You Yahoo!?
