DNS Issues



  • Hi,

    I've installed pfSense on a Mini PC, completed the wizard and then followed the vpn.ac tutorial on how to install OpenVPN client on pfSense:-

    https://vpn.ac/knowledgebase/63/OpenVPN-on-pfSense.html

    However I'm having intermittent DNS issues where some sites will not resolve over the VPN, if I disable the VPN all works OK.

    Here is a typical result when the VPN is enabled.

    C:\WINDOWS\system32>nslookup google.com
    Server: pfSense.localdomain
    Address: 2401:a400:2303:b000:2e0:4cff:fe68:1bb3

    Non-authoritative answer:
    Name: google.com
    Addresses: 2404:6800:4006:804::200e
    172.217.25.142

    C:\WINDOWS\system32>nslookup dnsleaktest.com
    Server: pfSense.localdomain
    Address: 2401:a400:2303:b000:2e0:4cff:fe68:1bb3

    DNS request timed out.
    timeout was 2 seconds.
    *** Request to pfSense.localdomain timed-out

    C:\WINDOWS\system32>

    Does anything need to be changed in the DNS Resolver setup as I've left this at the default?  Or, maybe some other issue.

    TIA
