IP OVERLAP



  • I have this issue on my pfsense

    WAN is DHCP with the following adress 192.168.90.47 comes from Mikrotik

    I wanna set up my LAN with 192.168.89.1, since my of the services that we have use 89.X

    But I keep getting this error:

    IPv4 address 192.168.89.1/24 is being used by or overlaps with: WAN (192.168.90.47/22)

    Any help please

    You need to change your LAN subnet.

    192.168.88.0/22 uses up the following ip address space :-

    192.168.88.1 - 192.168.91.254

    It's a very large subnet mask for a WAN interface.



  • Thanks for answering, I'll look into it, because the place where I am installing this, has a server with a fixed 192.168.89.2 IP, and that can't be changed, since it's the domain server, any idea here?
