Amazon.com not resolving when using rules for NordVPN OpenVPN setup
so I have NordVPN setup to allow my whole network to access the VPN tunnel via OpenVPN and Pfsense. The weird part is when I set the firewall rules to allow only certain PCs to access the VPN, the machines which are not set to access the VPN are not able to access sites like Amazon.com. Now I could understand if this was happening the machines using the VPN but this is the machines that are not set to use the VPN via the firewall rules.
My setup is pretty straightforward, I have the client setup as per NordVPN guide, I then have an interface assigned to the vpn client using DHCP as per the NordVPN guide. From there I have NordVPN DNS servers added to the existing google DNS servers in the general settings and also DNS resolver set to use the NordVPN interface. After that I set the outbound NAT rules and set an Alias which is then set to access the VPN via a simple firewall rule.
The only piece I am wondering about is, is the DNS resolver set for the NordVPN interface causing none VPN machines issues in resolving a DNS path?
Is there anything else which would cause DNS issues like this? (At least I presume it is a DNS issue as everything else seems to be working fine) I don't have any DNS leaks.
So as an update, the reason it seems that I could not get to certain sites was due to the machine involved had not been assigned an IP by the Pfsense DHCP server and so it was not routing correctly. I ended up assigning a static IP to the machine and then forcing it to a new IP which resulted in the machine now working as expected.
