From openPMA

Contents 1 hardware 2 build the software 2.1 iptables/netfilter 2.2 setup 2.3 dnsmasq

[edit] hardware

• the pma has a prism wifi card that can work in ap(acess point) mode
• you need an usb wired card, the compatibilty list is avaliable here

[edit] build the software

• first we can test the ap mode:

cardctrl insert # that brings us the card because it's disactivated by default
iwconfig # get you the name of your wifi card
ifconfig eth0 up # if your card is eth0
iwconfig eth0 mode master
iwconfig eth0 channel 1 essid "test"

then you can on your desktop use your favorite wifi tool in order to see if you can see your pma 430

[edit] iptables/netfilter

we need iptalbes and netfilter in order to transfer the connection comming from one interface to the other: so we need:

• an aimage.img with netfilter inside
• iptables compiled for the pma

iptables is the userspace tool and netfilter is the kernel part
