VLAN tag on more than 1 interface

@JKnott said in VLAN tag on more than 1 interface:

I suspect he's talking about one VLAN on the WAN interface and one on the LAN

Is that what your talking about @ncm-com.. Vlans outside of pfsense have zero to do with pfsense..l

Please explain exactly what your wanting to do... Your statements as of now don't really make any sense..

You can not place the same vlan on 2 different interfaces in pfsense.. You can't.. You could create a bridge or lag if you want 2 different physical interfaces to be in the same vlan.

As to what your wanting to do with esxi? Do you want it to handle the tags or pass those tags on to pfsense? 4095 vlan id in esxi will pass the tags, any other setting will strip tags.

Thee would be be zero point to creating multiple vnics in esxi and handing them to pfsense and putting them in the same vlan..

I am more than happy to try and help you - but currently have no idea what your trying to accomplish..

Many thanks
You can not place the same vlan on 2 different interfaces in pfsense.. You can't.. You could create a bridge or lag if you want 2 different physical interfaces to be in the same vlan.

So I think I have to create a LAGG in order to sent traffic through both interfaces? any idea how to do this? I guess I have to create the firewall rules as I can't add the existing VLAN to a new LAGG interface

Thee would be be zero point to creating multiple vnics in esxi and handing them to pfsense and putting them in the same vlan..
there are physical switches connecting outside the esxi so it would be an advantage to untag/tagged traffic to another port

You can place the same VLAN number on more than one interface. I just did that. I created VLAN 3 on my WAN interface, which I already had on my LAN interface.

Why do you want to send traffic through 2 virtual interfaces that are the same network - that serves no purpose...

Perhaps you'd better describe what exactly you want to do.

That is not the same vlan... that is the same vlan ID.. Not the same vlan.. And even if pfsense doesn't stop you from doing that.. Its a horrible IDEA..

@johnpoz

Yes, I am aware of that and know there is no data connection between them, unless set up in routing. However, the way you wrote what you said left the question open. Regardless, we still need to find out what he wants to do. Earlier on, I got the impression he wanted VLANs on more that one interface, which is certainly possible, even with the same VLAN ID.

@johnpoz

Please see the above scenario,

I can use LAN1 interface goes to VLAN switch and LAN2 interface to the non-manage switch so the bandwidth will use both interfaces?

JKnott

@ncm-com

So, you want the unmanaged switch to be on VLAN 20? If so, then you'd have to create a bridge between LAN 1 & LAN 2. However, the better way would be to just configure a port for VLAN 20 on the managed switch, which would then connect to the unmanaged one.

But your pfsense is virtual... You handle the physical interfaces in esxi... let it do the tagging.. All pfsense needs to know is that its the "lan" and on vnic x

vmx is internal and would be 10ge interface to pfsense..

Forgot about that.

@johnpoz
I actually connect them to physical adaptors from the esxi

they are gigabit interfaces

johnpoz

Also what is the bandwidth getting you? Is where this traffic going more than 1 gig? Your wan, multiple other vlans?

Traffic between devices on the same network traffic doesn't even flow through pfsense... So why do you think you need more bandwidth and more than 1 connection into pfsense to leverage that more bandwidth?

Connect both of the physical nics to the same vswitch/port group..

This makes ZERO sense to setup..

What exactly do you think that accomplishes???

Connect your physical nics to same vswitch, and then break out your different vlans via port groups.

@johnpoz
the pfsense is a VM on the host, and I'm trying to send traffic out to different physical adaptors let say vmnic 2 and vmnic 3

Connect both of the physical nics to the same vswitch/port group..
I tried the above but no luck

I got it, I could untag VLAN 20 using the Vswitch connected to the vmnic2,

but let say if the traffic between VLANs reaching 500mbps it will create a bottleneck on one interface that would not be the case if the traffic using two ports?

For what purpose? The connect vmnic2 and 3 to the same vswitch and setup whatever load balancing or load sharing you want in esxi..

And how does putting 2 interfaces in the same vlan solve that problem?

Use different uplinks for your difrerent vlans.. vmnic 2 vlan X, vmnic 3 vlan Y... Putting vlan X on both vmnic 2 and 3 does what?? Put all your vmnics into same vswitch.. Use your port groups to break out the vlans. setup lagg of these 4 nics to your switch from esxi
