Class a network not working well?



  • Hello pfsense buddies! I'm trying to set up a class a network in our office but we're only a small company. When I first setup pfsense I reach for help in this forum and it worked! Thank you!

    My previous setup is


    WAN - DHCP (Obtain IP address automatically)
    LAN - DHCP Server (to give IP addresses) 192.168.1.1 / 24
            IP range 192.168.1.100 - 192.168.1.150


    Everything is working in the above setup. Diagnostic > DHCP Leases also works and lists everything in the network.

    But when I setup


    WAN - DHCP (Obtain IP address automatically)
    LAN - DHCP Server 10.0.0.1 / 8
            IP range 10.0.0.100 - 10.0.255.254


    It works when I setup it for the first time I have internet but does not show DHCP Leases (I don't know why it won't show), but after a few restarts the LAN dhcp server stops working and I had to revert back to my previous setting which is LAN DHCP Server 192.168.1.1 / 24

    Anyone know why it isn't working? I really like pfsense and I started to use freebsd to learn more about it. :) Sorry for the trouble



  • Probably a smaller but equal version of this.

    Not a good practice to use a /8, and you probably don't have enough RAM for 65000+ DHCP clients, make your range something reasonable.



  • Thank you cmb! I will remember that, thats why it was not working :)
