NAT for use with OpenVPN

eth0 is your external interface so try:

# tcpdump -ni eth0 icmp

Then ping 8.8.8.8 from your VPN client and see what shows up.

br0 is a virtual bridge interface. This is what they use to connect your 
internal interface and your wlan interface together (and maybe some 
more) so they look as a single entity and one physical network. This way 
they can have a single subnet spanning both those interfaces instead of 
multiple subnets which would probably confuse most regular users. :)
