Guest network pro

[jsn2233]

I'm looking to get one of these routers and would like to know what are the possibilities with VPN/DNS and guest networks. I currently use YazFi and am able to put multiple guest networks through different wireguard tunnels, is this possible with guest network pro? I understand the firmware for these routers are unable to use YazFi at this time.

Would I be able to use my Pihole on my LAN as DNS for these guest networks in combination with a VPN? I always use Merlin, so would this make things easier or more difficult? Are there any other limitations I should be aware of?

@jsn2233, if you haven't done so already, use the forum search feature to search for the many past discussions on the Guest Network Pro feature and how it works. (https://www.snbforums.com/search/1880148/?q=Guest+Network+Pro&o=relevance) YazFi is not supported on the 3006.102.x firmware. There are various past discussions showing how to setup Pi-Hole on Asus routers including how to setup DNS Director on the 3006.102.x firmware to route Guest Network Pro clients to Pi-Hole. For example see this link: https://www.snbforums.com/threads/guest-network-pro-pi-hole.94392/#post-977343

Example of the Guest Network Pro IoT profile VPN tab (from a RT-AX86U Pro) with existing VPN Client configurations (currently using Proton VPN and Nord VPN).

Edit to add: One can use YazDHCP to configure manual IP reservations for Guest Network Pro clients. See the YazDHCP GitHub page for more.

For certain YazFi options like one-way or two-way to guest one will likely have to use custom IPtables scripting to accomplish the same/similar under Guest Network Pro. There are a number of past discussions on IPTables and Guest Network Pro that can be found using the forum search feature.

Ok cool, thanks man. Will do a deeper search next time as kind of did a surface search to see what was possible and didn't see much I understood, so wanted a definitive yes or no.

Good to hear I can do that with DNS director still. So it is possible to still route different guest networks through different VPNs by using something like VPN Fusion or those screenshots you just posted? It's hard for me to understand as I don't have hands on experience yet.

I always hear things are possible and then find the dumbest bugs that stop my use case so just wanted to be sure.

Asus Merlin firmware has a VPN Director which is similar to VPN Fusion in the stock Asus firmware. A very quick and dirty test assigning one of my IOT Guest Network Pro profiles to a active VPN Client does appear to route those Guest Network Pro clients through the correct client VPN even though the VPN Director is not configured to route that Guest Network Pro's IP address subnet through a VPN tunnel. Someone who has more experience with Guest Network Pro and VPN will hopefully chime in with their experience. For more on the basics of Guest Network Pro see the following Asus support document, and the various links within it, if you haven't already.
