HostAP-mode functionality in Version
3.1. As with FreeBSD, the support comes native in the core operating
system and not through a piece of third-party software. The FreeBSD
and OpenBSD projects share a great deal of wireless code, and the
HostAP functionality is no exception. Generally,
the same capabilities that exist in FreeBSD exist in OpenBSD as well.
When setting up an OpenBSD access point, you should start out with a stripped-down and secured kernel. For a discussion on compiling a locked-down OpenBSD kernel, see Section 6.2. There should be little difference between a client kernel and an access-point kernel. Both devices are in vulnerable locations on the network and should be treated the same.
At this time,
HostAP mode is only available on Prism-based
cards. Be sure you are using a Prism card and that you have the Prism
wi) compiled into your kernel. This
section describes how to make a bridging access point. This will
allow devices on the wired and wireless side of the access point to
be in the same broadcast domain. Most firmware-based access points
work this way and provide flexibility in your network configuration.
You must compile bridging support into your kernel by adding the
following line to your global configuration file:
pseudo-device bridge 2 #network bridging support
The number following the bridge device indicates the number of possible bridges the host will be able to configure. For a standard ...
