Change wan ip on flint

Hi all

I have a flint router and have wan set to pppoe

How can I change the ip of the WAN?

I don’t understand what you mean.
In PPPoE mode, the router obtains the IP address by negotiating with the PPPoE server. If you want to change the IP address, you should talk to your operator.
If you need to set the IP manually, you should use the Static IP mode.

If I have a range of IP addresses associated to my broadband then I need to be able configure my wan address. Using static won’t work because I need to authenticate with credentials
