Is it possible to create a guest network for other users by setting filtering on the poppy address on the router?

Question

network hardware

A question. There is a TP-Link archer c20 router. An adsl modem promsvyaz h208l is connected to it. As I understand it, I can create 2 access points: one for the office, for example, and the second for a guest (as it is called in the settings). I need to have access to the first subnet devices poppy addresses which are set. I implemented this by filtering poppy addresses in the settings of the router itself. But after that, access to the guest network is denied. Did I do something wrong? Or can't it be done? If it is possible, please explain how this can be implemented, otherwise I was busy with this for a very long time. Thanks

Answer 1

nothing protection, almost like poppy filtering on an open network =)
This is done through iptables, but on standard firmware it is most likely impossible to manually set rules, try open-wrt or the like.

Answer 2

Tp-Link has such a feature that it is impossible. That's it with the routers of this manufacturer, I always came across this.

Answer 3

There is no point in such filtering, do not fool yourself with this function, since it is a rudiment.
