  • 1.  DNS client lookups not working

    Posted 06-03-2020 06:18

    I think I'm having one of those days!


    I have Windows PCs. I've just changed some clients to use only their respective SRX for DNS lookups. However, the clients cannot resolve anything. As soon as I flick back to for example they are fine. The SRX devices all have the following config (only) relating to DNS:


    system {
        name-server {


    What really obvious thing am I missing? Configuration of a client DNS service somewhere?

    This configuration is for DNS lookups performed by SRX itself such as name resolution for domain names in the config, or when pinging/tracing.

    If You want SRX to return DNS answers to Your clients, You need to enable DNS proxy

    Simple it was, as follows:-


    # set system services dns dns-proxy interface ge-0/0/0.0
    # set system services dns dns-proxy default-domain * forwarders
    # set security zones security-zone Trust interfaces ge-0/0/0.0 host-inbound-traffic system-services dns
