iptables not working for pppoe interface

Reported by: cz <chengzhicn@…> Owned by: developers
Priority: highest Milestone:
Component: base system Version: Barrier Breaker 14.07
Keywords: iptables Cc:


I'm running BARRIER BREAKER (14.07, r42258) x86 on vmware, configured with two nic, eth0 for lan and eth1 for wan.
here is my /etc/config/network:

config interface 'lan'
        option ifname 'eth0'
        option type 'bridge'
        option proto 'static'
        option ipaddr ''
        option netmask ''
        option ip6assign '60'

config interface 'wan'
        option ifname 'eth1'
        option 'proto' 'pppoe'
        option 'username' 'abcdefg'
        option 'password' '123456'

after pppoe-wan is up, I run

iptables -I INPUT -i pppoe-wan -j LOG

to log every packet INPUT to this router
but when I run

wget -O /dev/null

I got nothing in kernel log

From /etc/sysctl.conf:


Change it to 0, run sysctl -p and see if your rule gets called again.
