RT-AC68U

How do I create multiple DHCP servers on my ASUS RT-AC68U Merlin router for my VLans?

 

[ColinTaylor]

You wouldn't typically create multiple servers but modify the current one to have a different scope for each VLAN.

Use a custom config file to modify dnsmasq.

How do I assign a LAN port 4 to a different VLan so that it will get a different IP address from 192.168.4.1 subnet automatically?

Search the forum for examples using the robocfg command.

This is what I see when I go into the CLI of my router:

How do I configure my router on LAN port 4 to use a different DHCP server on a different VLAN?

 

[ColinTaylor]

I don't know the specific commands because I've never need to to do it. But there are already numerous posts about this, including examples. Search the forum.

Help setting up VLAN on ASUS RT-AC68U

Hi everyone! I'm trying to setup a VLAN om my ac68u to separate my IoT-devices. I've been scanning the forum for clues but I just don't get it working :( So if someone could give some assistance it would be much appreciated! What I have: ASUS RT-AC68U running Merlin 384.7 192.168.1.1...

Does anyone know how to put LAN port 4 into a different VLan as right now all LAN ports are on Vlan1 by default on a Asus RT-AC68U merlin router?

@ColinTaylor

Currently on my Asus RT-AC68U merlin router, the default settings are being used and when I look at the VLan configurations, VLAN1 is where all lan ports are and VLAN2 is the WAN port. How do I create different subnets for each lan port after I created the VLAN 103?

 

[ColinTaylor]

Sorry, I don't know as it's not something I've ever wanted to do. As I said previously, there are numerous posts that already cover this so I suggest that you search for those.

I tried looking for some clear instructions on how to accomplish this on the forum but I didn't seem to find anything. The only thing I found was how to create a VLan but not assigning a physical port
