Do you have the FORWARD rule which allows eth1 to forward to ppp0?
I assume, along with the other posts, that you are referring to this:
echo "1" > /proc/sys/net/ipv4/ip_forward
Which I did. Forwarding from eth1 to eth0 works. I just can't forward from eth1
to ppp0.
Does anyone know how to debug this? Is there a way to enable verbose iptables
logging? I tried wiresharking but couldn't see any data on my wireless network
(I didn't try it when I had a working NAT to eth0 though). My walking access
point (a.k.a., friendly office mate) has gone home for the evening, so I'll
have to try other things tomorrow.
