      @yupq6wlc79ts Hey
      See my rules
      The order of the rules is important
      I hope the picture will help you to understand how to do it

          I showed you an example of how you can implement what you need
          When part of the traffic goes to the tunnel and the other uses the default gateway

            Looks somewhat similar to what I already did, trying to figure out what I did wrong there!

            Also, it would have helped to understand "What you did".

              Can you explain what needs to be implemented ?
              What ip addresses should use the default gateway or use a VPN ?
              What traffic should not get into the tunnel ?
              What I see now from You is that all IPv4 traffic from Lan Net goes to the Internet through the NORDVPN gateway.

                Sure.

                Can you explain what needs to be implemented ?

                I have three Gateways:

                WAN - Only 5 specific devices should go via WAN.
                (Default Gateway) VPN-IPv4 - All devices should go via VPN IPv4
                VPN-IPv6 - Disabled

                What ip addresses should use the default gateway or use a VPN ?

                All devices should use default gateway VPN-IPv4, expect 5 devices which I want to send via WAN.

                What traffic should not get into the tunnel ?

                Not sure.

                What I see now from You is that all IPv4 traffic from Lan Net goes to the Internet through the NORDVPN gateway.

                Yes. That's correct, all IPv4 traffic goes to Lan Net to Internet via NORDVPN. All I want now is, 5 specific devices should go directly to the internet without VPN.

                So I started with 1 example of 192.168.1.253, and selected WAN_DHCP as a gateway. I don't get any internet via this rule, so I disabled it for now (screenshot). How can I achieve this?

                  Rules for 5 devices must be first
                  and the last one should be the rule for NORDVPN

                  A deny rule for IPv6 does not need

                    That's exactly how I setup my 1 device to test the rule but when I do this, I don't get any internet connection on my single device. That's the issue.

                      I understand your problem.
                      NORDVPN - OPENVPN ?

                        Yes, OpenVPN.

                        (sorry for late reply, since I am a new user with no reputation, I have to wait 120 seconds before I can reply, lol)

                            It wasn't checked. I checked it and tested the device by enabling the rule, No Internet on that device.

                                        The reason was, It kinda acts as a kill switch. If the VPN goes down, no devices will be able to connect to the internet.

                                        But my 5 devices aren't on VPN, so they should still be connected. What do I need to add/change here?

                                          Add a nat outbound rule for the 192.168.1.0/24 on the wan interface as I showed in the picture
                                          and 5 devices will be able to access the Internet via wan
                                          Do not delete anything

                                            Tada!

                                            @Konstanti - Thank you so much. That worked. I think I get now what you were saying earlier (no nat rule for wan), makes sense now that I get it. Lol.

                                            Appreciate it.

                                            So now, for each device I want to connect to WAN, I'll have to manually add the entry in the Firewalls - Rules? Any way I can combine all 5 of them in 1?
