This howto is a very brief summary of configuring a router to route between a home Ethernet LAN and a campus network via a Wavelan wireless link, using the OpenBSD operating system.
Most of this is a straightforward router setup, as described in the OpenBSD documentation. An extra step is necessary to patch the OpenBSD 2.8 kernel to correctly address the Cabletron PCMCIA - ISA bus adapter. The OpenBSD 2.8 boot floppy has the correct addressing, but the generic kernel does not.
