Personally, I've always felt this to be a bad idea, but I can't come up with a compelling reason to convince people not to do it. Is there a reason not to? or is it just a matter of keeping apples and oranges in their respective baskets? The only thing I can come up with is that you can ping the routers in question from outside your own net if you use 'real' IPs. -Adrian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
