Using LIFX BULB behind firewall?

Hi,
I am looking to use LIFX BULB behind firewall and would like to know which domain are necessary so I can make exception for them.

All I found online is that I need to allow TXP connections to: v2.broker.lifx.co on port 56700. Any other domains are needed (for activation, control, timer etc…)?
