Hi Jeremy,

try

iptables -L -v

this will give you additional information about your rules!

I don't think iptables checks if the interface exists on rule
insertion time. Which makes sense in my opinion, so you can add
rules e.g. for device ppp0 (or even all devices beginning with 'ppp'
as expressed by 'ppp+') before the specific device has been created.

hope that helps!!


have a nice day :-)
