VLAN Setup

[heyjim]

Hi,

I'm looking to setup a VLAN on my router (which has DD-WRT on) for my lab to keep it separate from the main network.

If the main network is 192.168.0.* and my lab is 192.168.1.*, will I still be able to access the router from equipment on the lab network (the router will be 192.168.0.1)?

Thanks

No,since it is a separate broadcast domain.

You would need to set up trunking, router on a stick, etc. so the different VLANs can communicate. You'd also need a management VLAN.

Thanks for the reply.

Sounds complicated - do you know if all that is possible through DD-WRT or would I be looking at some form of managed switch?

In one sense its good that the lab network wouldn't see the router so I could have a separate DHCP, DNS etc. but would also would like to login to the router to make changes.

if you have a router you should be able to route traffic. What router do you have? You don't necessarily need a management VLAN. It's a good idea to put management on it's own VLAN though with multiple devices.

Many home devices can do RIP routing. There is usually a tab or superuser option for it.

I have a Netgear WNR2000 v2 running DD-WRT.

On a bigger network I assume a management VLAN would hold routers, switches etc?

A management VLAN is just a subnet that contains the IP addresses of the interfaces that you would manage each device with.

Got it, thanks!

I'll have a play around and see what happens 🙂
