    Asuswrt Merlin:
    I have a bidirectional OpenVPN connection running on 2 Asuswrt Merlin routers (firmware is current).
    But, I cannot perform a "nslookup pc.client.lan" on the OpenVPN Server?
    What I would like to do is resolve client lan names on the server.
    Does anyone know of a solution?
    [I spent several days searching and trying but could not find a solution]

    server lan: 192.168.0.x
    client lan: 192.168.1.x

    Here is what I can do:
    client> nslookup pc.server.lan
    client> ping pc.server.lan
    server> ping ip-client-lan (e.g.

    Here is what I *cannot* do:
    server> nslookup pc.client.lan
    server> ping pc.client.lan

    Make sure DNSMasq is configured on both sides w/ the following directive.

    This tells the DNS servers to listen for queries from the OpenVPN tunnel's network interface. By default, they will only listen to the default network interface (br0).
