Are you starting your ipchains rules from /etc/ppp/ip-up ? In my experience, problems result when I have started my firewall rules before my connection is up. I don't have problems when I start my firewall rules from /etc/ppp/ip-up. If I start my rules when the machine boots, I have problems. Do you have some rule that is blocking port 53? -- Andrew
