[?] How to attach 2 PPPoE accounts to one ethernet card.

Hello guys

Could you please tell if it is possible to have two 2 dsl connection from 1 ethernet card ?
For example now I have only one: ppp0->eth0 , but I want to attach second accout from the same provide and route unprivileged users though another pppoe channel. something like ppp0:0->eth0. I need it because I as administrator want to have separate ip (visible to the world) then users behind the NAT. Currrently I use RP-PPPoE and I can not find any settings for ppp interface in config files.

Thank you for attention
