OpenVPN Connected but no internet

Hi,

I have recently bough VPS from @Abdullah (webhorizon.in)

Earlier I was using dedicated VPS for openvpn. Now I am switched to NAT VPS. The problem is when I am connecting to OpenVPN through mobile or desktop app. It is connecting to VPN but no internet is working. I am not expert in VPS so need help!

Please let me know if any screenshot or log to be shown here.

    Do you have iptables installed on your VPS? If so, you may need to add these lines to your config:

    iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -o eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -p tcp -i eth0 -d $eth0_addr --dport 80 -j DNAT --to 10.8.0.3

    Substitute with your IP and interface names.

    Yes, tun is enabel. For the port I am using from my given 20 ports. Like my internal IP is ending with 180 so I am using 18005 for OpenVPN

    But why are you using OpenVPN instead of wireguard which is faster than OpenVPN
    @Abdullah had linked both in his thread
    OpenVPN: https://github.com/Nyr/openvpn-install
    Wireguard: https://github.com/Nyr/wireguard-install

    Both scripts are well proofed , why not use them ?
    there is no problem in NATs as i am also using them at 2 locations . No issues faced

    Are you using your allotted ports ?

    Check your client.conf it should look like below,

    [Peer]
AllowedIPs = 0.0.0.0/0, ::/0
Endpoint = YOUR_NAT_IPV4:CUSTOM_PORT

    Could be your ISP. Try using v2ray. It works even if your ISP is blocking VPN traffic.

    If you are sure that the vpn is connected successfully (able to ping the server over the vpn) just no internet access, then sounds like iptables not set up correctly.

    I also bought a NAT VPS from @Abdullah recently and both of @Nyr scripts worked flawlessly for me. Did you use those or some other way? If you haven't tried those already I highly recommend reinstalling fresh using those scripts instead. Takes away a lot of the iptables/routing config issues that I used to struggle with in the past.

    I don't know why but I had this issue once, too. It had to do with which DNS I selected during Nyr's setup. I think only system resolvers option worked for me. Try this and/or change your end user device's DNS manually to Google DNS or Quad9/CF..

    You are missing NAT rules in iptables/nftables.
