Are you BGP peering with them or ? What is the other range of IP's you are using...are they private? Do you have more than 1 IP? How is your routing and IP address scheme setup? Yes, you can setup nat to work with this setup...but why? unless you have only 1 IP. If so, request a small subnet like a /30 or /29 from Qwest. Believe me, you may need it. Have them staticly route it to your BSD machine. Hell...I'll do secondary for ya if you ask nicely ;-) Problem is, who's IP's are those? Qwest's? Someone has to delegate them to you in DNS for you to do primary on them. Nick Rogness <nick@rogness.net> - Keep on routing in a Free World... "FreeBSD: The Power to Serve!"
