Configuring Kernel PPP
Kernel PPP is handled by the pppd daemon. The main configuration files for the pppd daemon are located in /etc/ppp. Other than the files located here, you will also need to edit the /etc/resolv.conf file.
The /etc/resolv.conf file determines how FreeBSD resolves hostnames to numerical IP addresses. Each line in resolv.conf contains the keyword nameserver followed by the IP address of the DNS server. In addition, the keyword domain can be used in this file. If the domain keyword is present, FreeBSD will assume that any unqualified hostnames (hostnames that do not have a domain after them) are located in the domain specified after the domain keyword. Here is a sample of an /etc/resolv.conf file:
domain samplenet.org ...
