Hi@debutantrout,

May I confirm whether your problem is that after you set up Private VPN, the network works normally but IPTV does not work properly? How did you know that it does not work properly? Can you provide a screenshot of the relevant error message?

Please provide the configuration information, such as the relevant protocols and ports used (if it involves personal privacy information, please cover this information).

In addition, Archer AX73 supports VPN client and VPN server. You can also refer to the following instructions to confirm your needs:How to Establish a VPN Connection on TP-Link Wi-Fi Router?

Hi@debutantrout,

Do you get any error messages on your TV? Please send me a screenshot of the error messages.

Did the TV work properly when connected to the SFR.NB6? Is the working mode on the NB6 wireless router mode or bridge mode?

Please try the following suggestions:
1. Please contact CyberGhost customer service to confirm whether their service supports IGMP/UDP multicast protocol?
2. Try to switch the VPN protocol to WireGuard or OpenVPN UDP (to avoid TCP protocol interfering with streaming). It is best to consult your VPN service provider for support.
3. Connect the TV directly to the LAN port of the SFR.NB6, completely bypassing the AX73 VPN.
4. Enable IPTV function on the AX73: set the path to Advanced Settings → IPTV → Enable IGMP Proxy/VLAN Tagging.
