11.4 ipr0 Setup in /etc/rc.conf
The configuration of the ipr0 interface is done at system startup time using the normal FreeBSD mechanism using the /etc/rc.conf database. The section for my gateway looks like this:
- network_interfaces="ed0 lo0 ipr0"
# List of network interfaces (lo0 is loopback).
ifconfig_ed0="inet 22.214.171.124 netmask 255.255.255.0"
ifconfig_lo0="inet 127.0.0.1" # default loopback device configuration.
# => provider
ifconfig_ipr0="inet 126.96.36.199 188.8.131.52 netmask 255.255.255.255"
This all looks quite usual - with one exception: the ipr0 interface gets the same IP address as this machine's Ethernet interface. This is a legal thing to do and very convenient because it simplifies things very much.
