U Linksys WRT54GL sam ubacio DD-WRT firmware, v24 preSP2 [BETA] Build 12188.
Vazno je samo da se pocetno flashiranje obavi sa mini_generic.bin pa tek nakon toga nadograditi na standard generic.

DD-WRT mi djeluje malo buggy ali radi dobro.

Prije flashiranja, obavezno procitati:

Prije flashiranja trebalo bi preuzeti orginalni najnoviji firmware u slucaju problema s DD-WRT, trebalo bi preuzeti i Tftp.exe upgrade utility:

Ako nesto ode u krivom smjeru i primjetite da lampica power stalno blinka cak i nakon resetiranja:

The WRT54G Revival Guide

Naravno, ovo sve koristite na vlastitu odgovornost i mozda ce te izgubiti garanciju!

Došlo je vrijeme za promjene.

U 10 mjesecu, sada davne, 2007 godine na P1 Siemens Nixdorf SCENIC PRO C5 (CPU 133MHz, RAM 64MB, HDD 1.2GB), ubacio sam dva NIC-a (RED + GREEN) te instalirao IPCop 1.4.16, ubacio nekoliko addona (Advanced Web Proxy, URL filter, Banish),
malo podesio i radio je kao sat. Malo je ta konfiguracija slabija ali cist dovoljno. 8 portni switch GREEN, RED ADSL modem.

Odlucio sam ubacit i wireless te zamijeniti postojeci hardware.

Slozio sam od starih dijelova jedan stroj,
Celeron 900 Mhz, RAM 450MB, HDD 20GB, 3 x NIC (GREEN + BLUE + RED).

Ubacio bi Linksys WRT54GL, Linksysa bi zakacio u BLUE, switch bi ostao GREEN a RED na ADSL modem.
IPCop 1.4.20 je podignut na ovom Celeronu, ovo sad leti u odnosu na P1.

Sad ce bit vise mogucnosti za addons.

Slijedi umrezavanje i podesavanje.

Jos jedan zgodan addon za IPCop: http://www.ban-solms.de/t/IPCop-wlanap.html
