Smoothwall - VLAN

[DDR5]

After a little help if poss.

 

I'm wanting to get a guest WiFI onto it's own VLAN and want to use Smoothwall to do this. 

 

I've created a new interface and given it an IP and the 'parent' is port 3 on the Smoothwall and have tagged it.

I've created the DHCP scope and enabled it and I assumed that if I connect a laptop straight into port 3, I'd get a DHCP address from Smoothwall, but I'm not. I can't even ping the gateway when putting a static IP in. I untagged the interface and still get nothing. Anything stupid/obvious I'm missing?

 

Thanks

what kind of interface have you created? if port 3 is just a regular untagged port not being used for anything else you should add the ip address onto port3 interface not add an interface on top of it?

I've just been revisiting this as Smoothwall support assisted me. I haven't delved into VLANs before but slowly getting my head around it. In school, port 1 on Smoothwall is the basic interface for our LAN. Then we have port 4 for external which is for the Internet. Smoothwall configured port 1 so the new VLAN sits on that and they confirmed all is setup as it should be.

 

My problem still remains though and I can't figure it out. I've created a VLAN (VLAN 9) on the switch that Smoothwall is connected to, and configured the port so it is untagged for VLAN 1 traffic and tagged for VLAN 9 traffic, and I then connected my laptop to port 2 on the switch and untagged it for VLAN 9 and removed it so it's not a member of VLAN 1. In my head, that should work??

Netgears have a nasty gotcha which you need to edit the PVID too. The port you are untagging needs the PVID changing aswell, usually the PVID is set to 1, you will need to chnage port 2 to PVID 9.

Ah, thank you that now works. I was just wanting to test on a wired connection.
