RED at a remote network

Question

I have RED device deployed at a remote network in a standard/split configuration. When I tried to connect a Sophos access point to the remote network, it never appears in the pending access point list on the XG Firewall.

Am I missing any configuration change for the RED connection?

Is it configure a split DNS server address or Add the IP address of the access point to the split networks?

Cebu_XG, 
 make sure you define the networks that must go to the XG tunnel and add 1.2.3.4 as additional network. 
 Sophos APs search their AP controller on IP 1.2.3.4. Once that request reaches XG, you will see the AP and then the AP will receive the proper IP.
