The cable modem is from Com21, and the cable company can barely understand the Win/{95,NT} that they support. They *sure* don't support/understand anything else. I suspect (and may find out) that the uplink is standard PPP. At least, they didn't give me anything with a special IP driver in it... The cable modem is expecting to talk to 10.0.0.1 . I'd *love* to be able to run this with NATD on a FreeBSD box, so the rest of my network can use this way to get data from the InterNet. For this to work, however, I suspect I'm going to be dealing with asymmetric routing out of the box: a "local network" NIC card a NIC card for the cable modem ( I suspect I could use an IP alias and a single NIC card, but why take the security risk?) at 10.0.0.1 a PPP tunnel (with whatever IP address the cable company tells me it will be, that will probably end up being my default route to the internet) Here's where I have my doubts about NATD - the incoming translation will need to be on the local NIC stuff, and while outgoing packets will be headed over the PPP connection, the returning packets will have a destination IP address of 10.0.0.1. Is NATD smart enough to handle this? H To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
