Hello, First of all I would like to say that my English is not good. but I hope someone understands me. I bought a GL MT300N v20 and installed my CyberGhost data on it. everything was accepted and the VPN icon lights up green. my TV (samsung) is connected to the mt300n v20 via lan and everything runs via the VPN. Likewise, if the TV is connected to the mt300n v20 via wifi, everything runs via VPN. so far so good But as soon as I connect to my tablet, cell phone or PC I can't access the internet. Without an active VPN on the mt300n v20 everything works wonderfully. Can someone tell me which settings I need to change. My main router is an ADB VT5920 connected with cable from port1 to wan (mt300n v20) My internet provider is Brennercom. I live in Italy. Can somone help me? ---

Please do a `ping forum.gl-inet.com` and `nslookup forum.gl-inet.com` from your PC while connected to VPN. Send the results back to this thread. ---

Can you explain to me step by step what exactly I have to do? Unfortunately, I'm a noob when it comes to networking. I have to in cmd Enter ping 8.8.8.8? and then nslookup? ---

Exactly. You can use the commands in `cmd` just like I wrote them. ---

Ok, so the issue with your devices is that there is no DNS server they can talk to. Please execute `ipconfig /all` and show the result. ---

Ok, the issue is that your DNS server is failing. * * * I'm not quite sure how you installed CyberGhost. Is it WireGuard or OpenVPN? Which DNS server have you stored in the router? ---

Can you post the OVPN config here? Please omit the keys or passwords if they are included. I am talking about the MT300n. The ADB isn't relevant for this issue. ---

In that case, I can't really help since I am not familiar with CyberGhost. The only thing I can tell for sure: DNS resolution on your MT300 is failing as soon as you are connected to CyberGhost. I am not sure why this happens, but maybe it will help you to figure out what to change. ---

Thanks for your help. Maybe another member of the forum who works with cyberghost will get in touch. The only strange thing is that everything works on the TV, but the devices (tablet, phone and PC) don't connect ---

Just out of curiosity, please try this. Go to Network \> DNS and change your DNS to - mode: manual and select cloudflare for example, click apply. Now change back to automatic and apply. See if that helps. [Next page](https://forum.gl-inet.com/t/cyberghost-on-mt300n-v20-ot-works/44201.md?page=2)
