Simply what you need is allow your filrewall for traffic (5246 & 5247) from AP6 & 7 vlan to your WLC management.
If you already sent these to branch then you can configure DHCP option 43 under Vlan 30 to advertise your WLC IP to your AP. Otherwise if you have AP console access you can simply configure WLC IP address statically on the AP using below command.
LAP#capwap ap primary-base <controller_name> <controller_IP_Addres>
If it is still in your main office you can put it to vlan 1 & register them to your 2504. Once register, you can go to AP (Wireless ->Select AP -> High Availability ) & put your WLC name & IP address in Primary controller information via GUI as well.
So then AP will always come & register to your WLC as long as it has IP reachability to your WLC.
Refer these post for more understanding about AP registration.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
