I have dumped the entire config so others can use this as template for their own PF setup or to shout OMGWTFBBQ u freakin' n00b you should do it like XYZ.

In the latter case either drop me an e-mail (psychic [monkeytailthingie] ackspace [lowerroundthingie] nl , join ACKspace and help out or simply STFU =D


MEUK

Meer devices maken anders breekt DHCP enzo.... gewoon genoeg aanmaken, hier worden er 20 extra bijgemaakt. 

`cd /dev;for i in {10..30}; do ./MAKEDEV bpf$i ; done`


Pad toevoegen om packages te downen
