PPPOE dial
Subnet mask is 255.255.255.0,but interface wan is no correct,so need to check.
Maybe upgrade to deal with ISP hijacking or ISP servers have loophole or leak.
Thank you!

Sry. What do you try to tell us with your post?

Example: The gateway address 223.156.140.1 obtained by dial-up Internet, the subnet mask is always 255.255.255.0, but the client address becomes 223.156.143.82, this is a problem, the normal client address should be 225.156.140.2- 255.156.140.154, sometimes it is a normal address, but most of the time the address obtained is offset, 140+2 or 140+3, this is wrong, I don't know how to solve it, the OPENWRT system also has this problem , Please check to see if the upgrade can be resolved, thank you!
With many different devices, OPNSENSE can dial correctly occasionally, and I hope it can be resolved.

The subnet mask is set up during LCP from the provider, you have to get in touch with them if you think this is an error.
