DW> Doug White | FreeBSD: The Power to Serve DW> dwhite@resnet.uoregon.edu | www.FreeBSD.org Doug, thank you for responding. I understand the firewall is blocking the packets. As I mentioned in my original message, the firewall should block them because the machine is trying to send these packets to the address it held during the preceding dial-up session for some reason. I am trying to figure out why it needs to do that. Furthermore, why would the machine need to send them from port 53 when named is not running on it. Natd is already running when a ppp session is set up each time. So is ipfw. Ipfw is configured thourgh its own configuration file. So, it seems I shouldn't have to set anything extra up in the ppp.linkup. I am just trying to first figure out why the machine is even trying to send those packets from port 53, among others, to an address it held during the previous ppp session.
