Hello, I took my old IB and converted it into an AP by following the instructions placed on the post “reusing an old Internet-Box Plus as access point” by @lucaberta.
All is working well except for the guest network.
I can connect to the Wi-fi main network, but cannot to the Guest one.
Any ideas on how to make it work?
Thank you.
Hi @Destauneu27
This is because the IB2 still tries to act as a router for the guest network, and therefore “eats” the packets instead of sending them to the IB3.
You also might experience some DHCP conflicts in the guest network when using this setup.
As there is no way to configure this, this is unfortunately an “unfixable” issue. The only way to make it work is to use other access points, i.E. a WLAN Box 2 or 3 instead of the IB2.

Thank you. What strucks me is that it works as an AP for the main network, but not for the guest one.
DCHP has been disabled to avoid conflicts.
Hi @Destauneu27
DHCP has been disabled to avoid conflicts.
You can only disable DHCP / change the IP for the main network. They are always enabled/the default value in the guest network.

Would it work through Port Forwarding?
Hi @Destauneu27
Port Forwarding is not available for the guest network and would sadly not solve the issue mentioned.

Why they make things so difficult? Not great.
It’s just not designed to do that. It would be nice if it had the functionality to work as WLAN-Box when connected to an existing router. Guest network is on a separate VLAN, port forwarding can’t help you here.
