I need to change LAN ip-addresses from 192.168.10.xxx to 192.168.100.xxx

I haven't been able to find a spot where to do it?

    If you have 50 devices with DHCP set for x days and you change the LAN subnet on the flex you have to reboot devices or wait x days for them to get the new IP in that subnet or change lease time to 3mins wait x days on the old lease then change the IP subnet and your devices will get a new IP in that subnet in 3 mins

    I don't recommend 192.168.100.xxx if you have a modem thats on 192.168.100.1

    Hi @MattiS ,

    Please see PeterUK's recommendation firstly.

    If you still want to change your LAN IP addresses from 192.168.10.xxx to 192.168.100.xxx, you can follow these steps:

    1. Navigate to: Configuration > Network > Interface
    2. Select the LAN interface you want to modify (e.g., lan1)
    3. Update the IP address
    4. Adjust DHCP configuration if necessary

    I want the LAN ip addresses to be 192.168.100.xxx. F.eg. Printer address is in the old firewall 192.168.100.200, so I want the printer to be the same address in this new Flex50.
