hi people.. i have question regarding ipfiltering and pppoe..

here at the office we have a pppoe connection.. i'm using ipfiltering to 
block packets, etc.. now.. my question..

when ppp connects via pppoe, my nic (rl1) is not assigned an external ip 
address.. however, the tun0 interface is.. when i'm designing my 
ipf.rules file, should i set the rules to block and/or pass on rl1, or 
the tun0 interface?

same goes for my ipnat.rules file.. should i map the rl1 interface or 
the tun0 interface?

any help would be appreciated..
