Configuring the network devices

Previous  Top  Next

We will use the network interfaces rl0 and rl2 as our bridging interfaces, rl0 being the internal and rl2 being the external interface. To tell OpenBSD that we want these interfaces up yet do not want an IP address we create two files:

·

/etc/hostname.rl0

·

/etc/hostname.rl2

that contain only one line:

up

This is equivalent to typing ifconfig rl0 up. We will however configure interface rl1 to be our management interface that we can connect to in order to perform administrative tasks.
