Add reference to Bridge-NF

I had issues setting up the bridge, before I realized that bridge-netfilter filtering must be turned off.
Symptoms
- Can ping external server from host
- Can ping DHCP server (in Docker) from host
- Cannot ping host from external server or vice-versa
Solution
Disable bridge netfiltering on the host.
# sysctl -w net.bridge.bridge-nf-call-iptables=0
# sysctl -w net.bridge.bridge-nf-call-ip6tables=0
Could you add this as a hint to the README?

Wow, I never ran into that :-o
Are you sure that it was the problem, and that it wasn't a side-effect of something else?
Can you indicate which distro you are using, which kernel version, and which version of Docker?
Thank you!
