Can Guest Network Pro (guest network #1) use a DNS server which is located in the main LAN?

[Rici]

Hi,

Since I am not sure about the internal routing mechanisms of the Guest Network Pro towards the main LAN: Can my Guest Network clients use a pi-hole located in the main LAN?

My router is RT-AX86U Pro running Merlin FW 3006.102.6 .

Thank you!

If they are on a separate VLAN, then no - that's the whole point of using VLANs, to isolate networks.

It will all depend on how you initially setup the Guest Network Pro profile. If you enabled the option Use same subnet as main network when creating the Guest Network Pro profile, then the Guest Network Pro profile clients one should be able to use a Pi-Hole on the main network as the client's DNS server.

If you disabled the option Use same subnet as main network when creating the Guest Network Pro profile, it creates an isolated network that generally cannot access the main LAN clients. Not sure if Asus fixed the Guest Network Pro profile Access Intranet option that was broken in early 3006.102.x firmware releases (at least on the RT-AX86U Pro).

If you have disabled the option Use same subnet as main network when creating the Guest Network Pro profile; see the following link/post which gives a general explanation of how to configure the Asus-Merlin 3006.102.x firmware with Pi-Hole so Guest Network Pro profile client(s) use the Pi-Hole. It involves using DNS Director.

Guest Network Pro Pi Hole

Hey everyone, I have an issue with DNS resolution that I'm looking for help with. I have a RT-AX88U Pro using Guest Network Pro and a raspberry pi4 running Pi-Hole. The devices on my LAN can connect to the Pi-Hole without issue, however devices on my guest network (VLAN) cannot. In the guest...
