I think you are going to have to configure the router to `punch through' dns requests to your bsd machine. The man pages on ppp tell you how to do that for ppp, and that might give you the jargon to go digging for in the router's manual. You need to tell it to direct messages on port 53(?) to 10.0.0.102. The only ADSL router I have experiened either doesn't have this feature, or has hidden it very well in the manual. I believe that many do, however. What should my > rc.conf files look like?
