    Hi,

    I have been running my n66 for a good couple of years now and love the merlin firmware. Now since i have updated to a new version (378.55 in my case) i thought i would have a go at using the selective routing with openvpn.

    I have my openvpn cilent via AirVPN up and running and i have selected it to only route one of my devices via the VPN. It seems to be working but i have a couple of questions regarding DNS.

    1. Can someone please tell me the difference in the vpn dns options of: Disabled,relaxed,strict,exclusive?

    2. How can i get all my normal devices to use comodo dns as it does now and then my one vpn device to use the airvpn dns?

    I could be wrong, but these would be my answers:

    A. 1
    Code:
    Disabled = DNS servers sent by VPN-provided DNS server are ignored
    Relaxed = DNS servers sent by VPN-provided DNS server are prepended to the current list of DNS servers, of which any can be used
    Strict = DNS servers sent by the VPN-provided DNS server are prepended to the current list of DNS servers, which are used in order (existing DNS servers are only used if VPN-provided ones don't respond)
    Exclusive = only the VPN-provided DNS servers are used
    A. 2

    Just to let you know that worked.


    But today i had no internet connectivity, long story short i did not have the openvpn client running and for some reason all my clients decided to use the vpn dns even thoe via parental control i selected just the one device to use this.

    i can not work out why this would happen?
