Hans Rosenfeld ported EtherIP support from OpenBSD to NetBSD 2.0. Today I’ve committed that work to NetBSD-current, to be included in future releases of NetBSD.
EtherIP (RFC-3378) makes it possible to bridge Ethernet networks using tunnels over the Internet. While you could already use tunnels for IP traffic, now they can be used for any Ethernet traffic. I’m looking forward to using the Internet with my friends to play legacy networked games that only use IPX for LAN communication.
To setup a bridged network using tunnels, you need to create gif(4) interfaces for the tunnels, and a bridge(4) interface to connect the tunnels and the Ethernet (LAN) interfaces. (more…)
