| 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.
- Ram: 64Mib (PC100 or PC133 sdram)
- Storage: 128Mib compactflash
- CPU: ??? (pentium II or III to be confirmed)
- Network: 6x 10/100Mbit
- Serial Console port (RJ45 on the front panel)
- Powerconsumption: ??? to be measured.
Firewall OS Possibilities
- Default Wathcguard OS (are you nuts?)
- pfSense (current amount of ram and compactflash storage are too small, ideal minimum would be 512Mib ram and 2 Gib compactflash
- other, suggestions are welcome
Installing m0n0wall / flash the image to compactflash
- Long version can be found here: http://doc.m0n0.ch/quickstartpc/index.html
- Stuff you can't do without is here below
(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)
- 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. (so with M0n0wall, 4 out of 6 networkports are unused)
- 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)
- Ram is upgraded to 384 Mib an pfSense is flashed to a 4Gib compact flash (both kindly donated by Firemonkey ) Unfortunately the firebox won't boot of the 4Gib card, or the image is flashed wrong
pfSense and Generic x86 or x64 hardware
pfSense can run comfortably on any x86 or x64 platform, if you observe some minimum requirements.
- Absolute minimum is a cpu with 266 Mhz and 256 Mib ram. This means no extra features, such as snort or squid.
- CPU intensive tasks are (in the order of intensity): VPN encryption, layer 7 filtering, traffic shaping, snort squid, ...
- Memory intensive task are (highest memory requirement first): snort, squid and in lesser degree traffic shaping,
- Recommended is more like 1Ghz cpu and 1Gib of ram, 2 network cards (for easy setup)
Personally I always choose the fastest machine I can get, but power consumption must be less than 20 watts full load and idlleing at even lower power consumption. Here is a more hardware sizing page
Selecting install method
On the pfSense downloadpage you can find 2 categories:
- embedded installs, in the form of a nanoBSD image
- live installs, in the form of an ISO or memorystick image
All install methods have the same features, the only differences are the install method and targeted platform. The ISO and memstick image can be used as a live cd/bootable memory stick, with the option to install to harddisk. nanoBSD images are for embedded platforms and are installed the same way as m0n0wall (see above). The indications of 512mb, 1g, 2g, 4g are the size of the slice and BSD partitions and can not be bigger than the rated capacity of your compactflash card.
Personally, for a generic pc install, I prefer the memstick option, (who still burns CD's?) It's only necessary for really, really, really old pc's that don't have an usb boot option in bios. But those things are mostly or power guzzling, noisy boxes or just plain slow (ie no PCI bus throughput)
If it's the first time you meet with a BSD distribution, choose default or automatic options. So you don't have to wonder what the hell they mean with partitioning a slice means. ;-)
