Debian NAT via iptables - Won't work!!

Hi guys

I'm running on debian on a small embedded system. I have a ppp interface that is connected to the internet (and works). My unit also has wifi access point (which works and I can connect to it).

I want to allow connections to the wifi to be able to use the internet from ppp0 interface. So basically want to set up a router type system.
right now, when I connect to my device with my phone, I cannot use the wifi. But on the shell of the embedded system, I can ping, I can load pages, i can do all sorts of things.

Here is what I have set up for my IPtables:

Quote:

echo 1 > /proc/sys/net/ipv4/ip_forward

/sbin/iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
/sbin/iptables -A FORWARD -i ppp0 -o wlan1 -m state --state RELATED,ESTABLISHED -j ACCEPT
/sbin/iptables -A FORWARD -i wlan1 -o ppp0 -j ACCEPT

But i still can't browse internet on my phone.

Any ideas?

Thanks!

To do routing, you'll probably want to either set up routing (not the same as iptables), or bridge the two interfaces into one pseudo-interface (also not the same thing as iptables).
