<pre>Hello,
I find physdev match is not working.
I am trying to drop tcp traffic on bridged port but it shows no effect:
I run on machine with bridge:
~# brctl show|grep tap40
tap40
~# iptables -I FORWARD -m physdev --physdev-is-bridged --physdev-out tap40 -p
tcp -j DROP
Then from other machine I am trying to reach the IP behind tap40 interface with
telnet and getting connected.
~# iptables -nvL|grep phy
0 0 DROP tcp -- * * 0.0.0.0/0 0.0.0.0/0
PHYSDEV match --physdev-out tap40 --physdev-is-bridged
I find the physdev match has no effect.</pre>
