Two PPP interfaces
01 Jun 2000 05:40:24 +0000
I currently administer a LAN gateway system running netfilter which
performs NAT and firewalling for an outgoing (dialup) PPP
connection. I have now been to add the capability of having a dial-in
PPP connection, which will need completely different netfilter rules.
As I understand it the PPP interface number is allocated dynamically,
so it will not possible to always have ppp0 as the dial-out interface
and ppp1 as the dial-in. Currently all my rules for the PPP interface
use "-i ppp+" to identify them.
Can anyone offer advice as to how I can associate the correct
netfilter rules with the appropriate interface?
