How-to Discussions / Re: VLAN DHCP In OPNSense?

« on: May 06, 2021, 02:00:36 PM »

Is your computer that you are logging into OPNsense on the same default LAN network? By default OPNsense runs on 192.168.1.1. When working with VLANs, the default untagged VLAN ID is usually 1. So that means all ports on your switch that do not have any VLANs set will be on that default untagged VLAN 1. Make sure the computer you are connecting to OPNsense is on an untagged port.

Also, you will need to sure that the port on the switch that the OPNsense box is connected to is set up to allow all VLAN tags to pass through. Different network device manufacturers use different terms. Some call it trunk ports. The port the router is plugged into needs to be configured to allow all VLAN and untagged traffic if you are using the default VLAN 1 as the management VLAN. I think it's easiest to use the default VLAN.

I know some people prefer to change the management network to a different VLAN since it's easy to make the mistake of plugging a device on an untagged port and have access to the network management network. If you set all of your other ports to be in different VLANs (or may another default unused VLAN ID), then you would not have to worry about that issue as much.

Yes, that should be adequate to give you basic VLAN support. Unmanaged switches will often pass along VLAN tags, but you can't configure any of the ports to participate in VLANs, which is why you need a smart/managed switch. Once you have the switch, you will set up the same VLAN IDs on both the switch and OPNsense (or whatever router software you are using).

Are all of your switches VLAN aware? Also when you daisy chain your switches, you will need to make sure that the ports connecting each switch are configured to be as a "trunk" so that it will pass all of the VLAN IDs between the switches. The terminology for VLAN "trunks" can vary between vendors, but the concept is the same. You need to make sure the VLAN tags can propagate between all of the switches. That is my first thought on why you are not getting any DHCP addresses assigned if you are following the guide without knowing any other information about your configuration.

This how-to would include examples of writing a WAN firewall rule and using a NAT port forward firewall rule. Also, explaining the difference of when you need to use a WAN rule rather than a NAT Port Forward rule.
