Hi All,

I'm having a bit of a blank moment. 
 

Client has omada system, OC200 ER7206, with a TL-Sg2428p connected via fibre to an sg2210p. Several VLANs setup with switch ACLs to keep all separate, all VLANs have access to WAN. 
 

NVR is connected to the 2428p, port is configured for VLAN 12 which is the clients 'home' network.  
CCTV is setup for remote viewing via a P2P service from the NVR manufacturer. P2P servicing working correctly, externally. Once my client is connected via Wi-Fi to VLAN12, it fails to connect.  
 

I have added another SSID that belongs to another VLAN (15) to my clients local EAP and the P2P service works correctly when connected to a different VLAN. 
 

what am I missing here? Usually it ends up being the opposite way around with CCTV clients and it's not accessible externally, which is usually down to port forwarding failure. 
 

Any help would be much appreciated. 
 

Thanks, 

Sam
