Firewall
What:
With so many ongoing IT related projects, its always good to have some control over the Network Traffic.

Enable some extra services at the space or block some traffic from outside the space would just be a nice-to-have-toy to play with.

Firewall OS Possibilities

Installing m0n0wall / flash the image to compactflash

(use the -u flag if the target disk is > 800 MB - make very sure you've selected the right disk!!)

physdiskwrite [-u] generic-pc-xxx.img

(you must use v0.3 or later!)

gzcat generic-pc-xxx.img | dd of=/dev/rad[n] bs=16k

where n = the ad device number of your CF card (check dmesg) (ignore the warning about trailing garbage - it's because of the digital signature)

gunzip -c generic-pc-xxx.img | dd of=/dev/hdX bs=16k

where X = the IDE device name of your HD/CF card (check with hdparm -i /dev/hdX) - some CF adapters, particularly USB, may show up under SCSI emulation as /dev/sdX (ignore the warning about trailing garbage - it's because of the digital signature)

Status FireboxV60

The existing compact flash image, with the watchguard has been backed up to the homedirectory of Barputer and is called FireboxV60. Should someone feel the desire to restore to factory defaults.

The compactflash has been flashed with M0n0wall, Base system is recognised, but the specialty nic is not.

Looking to install pfSense (has more features, the kernel is easier to access so installing special hardware has a higher chance off success.

Hardware needs a Ram and compactflash upgrade for pfSense to run comfortably (min 512 Mib ram and 2Gib compactflash)
