Pfsense 2.7.1 killed all my IP Cameras

After upgrading to Pfsense 2.7.1 from 2.7 I cannot access any of my Hikvision IP cameras anymore, I cannot even ping them. Hikvision’s SADP utility to see the cameras on your network lists no cameras now.

Everything was fine under version 2.7, how do I get my back access to my cameras?

Shut down my entire network and restarted all switches and firewall and now they work again. I guess firewall needed to be restarted which never occurred before after previous updates when in 2.7 Beta.
