AP goes offline after dhcp change on customer site. Can`t reconnect to scg public ip

[christoph_pittn]

Ok. We use vsz-h with multiple customers connecting to it.

If you have vsz-h, confirm two point.

First, 
show run lwapp2scg    
LWAPP2SCG Configuration   
   --------------------------------------------------   
   ACL Policy                              : Accept all   --------------> Have to Accept All.
   Dynamic Data Transmission Port Range    : Not specified   
   NAT IP Translation in FTP Passive Mode  : Yes   
   ACL APs

Second, check whether the AP is located on staging-zone.

[christoph_pittn]

show run lwapp2scg shows "Deny all" on the controller.
I changed to "Accept all" and reconfigured the AP. But it still does not appear in Staging Zone.
