Hello, I just started to use an ADSL line with PPPoE and want run a firewall between it and my local network. What I am wondering about is that even if I only have the default everything-blocking rule (deny ip from any to any) I still see incoming packets on tun0 with tcpdump. Is this, because the firewall rules get checked after the packets leave the tun0 interface? On what interface should I run tcpdump then to check if my rules are working as expected? Dirk
