ethX is a port of br-fixed, eth1/eth2 are NICs of my VPN instance,
which connect to br-int through tap-XXXX.
Flow tables uses to transfer traffic between br-int and br-fixed.

Hi,
I'm using OpenVswitch and Openstack to build an instance with two NICs
named eth0 and eth1, both NICs get IP by DHCP of DNSmasq.
I also build a SoftEther VPN serice, eth0 is as management IP for SSH,
while eth1 as IP assignment when VPN user dials in.
Eth0 is 105.6/24 and eth1 is 108.7/24, when user dials in, eth1 cannot
get an IP for him. I use ` tcpdump` to find that phsical NIC(name ethX)
which eth2 of this instance attach to does not receive any dhcp request at
all.
I use `dhcpclient eth1`, ethX gets dhcp reqest and reply.
I guess `flow table` or something may drop requests sent by users when
he dials in. But it's hard to debug.
Any ideas? Thanks.
