When setting up DHCP Server, we need to set up the interface.

I suggest you set up a new interface and change the subnet mask to 255.255.254.0 in the interface, so that we can set the address pool 192.168.2.1 to 192.168.3.254.

I'm just giving you an example of something you can try.:)

good morning and thanks for the reply,

I currently have a GB1 interface (192.168.1.100 255.255.0.0) with dhcp server (192.168.1.2 -> 192.168.1.254) Gateway 192.168.1.1 and it works perfectly.

yesterday I tried to set up a new GB2 interface (192.168.2.2 255.255.0.0) with dhcp server (192.168.2.3 -> 192.168.2.254) Gateway 192.168.1.1 on a new Vlan on ports 3-4.

I assigned a part of the access points to this Vlan.

the result is that, on the GB2 the devices (notebook, smartphone etc ..) receive dhcp but ES: 192.168.2.56 gateway 192.168.1.1 but they are not connected to the internet.

I didn't understand how to get the internet on GB2.

Can you give me some suggestions?

Thanks a lot to everyone

I'm not quite sure what your topology looks like, but I found an FAQ on the official website of tp-link, and maybe this article is helpful to you.
