I ran into a similar problem. In my case I am only running a caching nameserver on my end of the ppp link. To get things up fine, I deleted my namerserver entries from rc.conf and made sure I had a good list of the root servers. However, I did also see the unwanted PPP traffic. You might consider adding a static route from and to your box that does not use the loopback interface. i.e. one that uses the PPP interface. I had to do this because I noticed that if I pinged my ppp IP the ICMP packet went down the PPP link and then back. The static route short circuits this loop. My machine is called lorax. Here is what I added to rc.conf: static_routes="lorax" # Set to static route list (or leave empty). route_lorax="128.143.244.37 127.0.0.1" Honestly, it seems that pppd ought to set this route by default. Anyone else agree?
