Use the downtime to set up your network the way you want it, with the FreeBSD machine connected to the CM. - Once the lease expiry time has come and gone, power up the CM and (new) gateway box. With a bit of luck dhclient will be able to get a lease. This definitely works with my cable provider (ntl) but will obviously fail if your provider caches MAC addresses more persistently. Probably still easier to just swap the NICs, or call them up and say "My NIC broke. Here's the MAC address of the one I'll be using from now on". When they ask what OS you're using, say "Windows". :-) Cheers, Scott -- =========================================================================== Scott Mitchell | PGP Key ID | "Eagles may soar, but weasels Cambridge, England | 0x54B171B9 | don't get sucked into jet engines" scott.mitchell@mail.com | 0xAA775B8B | -- Anon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
