So its only goodness that all three can borrow, or at least look over each other's shoulders.

Oh yeah, its (currently) got an 802.11g card in it, and boots from a CF slot. :-) Behind that, I've got a 1U 2.8GHz P4 appliance coming with 3 GigE and 3 10/100 ports. It also boots from a CF card. Soekris has some crunchier boxes coming out as well. Dismissing performance issued because m0n0wall is typically used on low-end embedded hardware (where such issues aren't as visible) is a poor argument. The WRAP/Soekris 48xx/45xx boards have their place. They're inexpensive, and deal with the realities of serial BIOS, etc quite well. I doubt anyone expects to be able to forward through them at wire-speed. OpenBSD, NetBSD and FreeBSD bring different mindsets to the table. I'd not bother with NetBSD except for the OpenBSD's "security uber alles" was originally a fine thing. Now its essentially marketing hype, since the playing field on that front is essentially level. Performance will soon level out, except where FreeBSD's VM continues to dominate on Intel hardware (and then only for applications that are sensitive to VM performance issues.) OpenBSD's legacy challenge remains the issues encountered when dealing with Theo, and the wireless HAL damage. YMMV. |
