Single Wan and Multi Lan Issue

  • PF Sense.jpg
    Hi all,
    I'm newby to PF Sense and I want to create this senario and the main hurdle is that and can communicate with each other. Can some one help me with it

  • You have to pay attention here on the network mask. Both nets in the 10. range need to have at minimum a 24 bit mask to make this work !
    Otherwise you have overlapping ip nets !
    Keep also in mind that you have to setup the right firewall rules on these interfaces !
    For first tests you should setup a "shotgun" rule with Source any to Destination any on both interfaces to check the allover connectivity.
    Later you can narrow that down to striker rules if you like or need to.

    Yup, what he said. 😉

    A common mistake here would be to use /8 as the subnet on both 10. subnets which would then conflict.

    If they are set as /24 pfSense will route between them by default. You would only need appropriate firewall rules to access hosts from the other subnet by IP address.


  • @lfoerster subnet mask for both 10 series is 24 but they are not communicating with each other

  • Do a packet capture on the pfSense interface, is traffic exiting ?

    Are you sure the subnet mask is correct on the hosts?

  • Netgate Administrator

    Then you only need firewall rules for pfSense to route that traffic.

    The respective hosts may refuse it themselves of course.
