DNS traffic always send to WAN interface ?


  • Hello everybody,

    we are testing pfsense in our network (as a VM), we have only 2 interfaces WAN and LAN, it our effort to test DNS, we tried to use DNS lookup command to reach our internal DNS server which is in the same subnet as the LAN interface ( I'm doing this command from pfsense itself),
    so we started troubleshooting, I can safely ping the internal DNS server and can do lookup from any external server.

    the next step was packet capture, we found out that the dns queries are always going to the WAN interface, even though it is in the same subnet as the LAN interface and even though the ping goes to the correct interface, also when we type the command route get for the dns server we get the correct route.

    anybody faced this issue before ?

    Thanks in advance
