How to get pfSense WAN to accept VLAN 0
-
This is my vlan0 script:

All I changed were the commenting of the few lines that @michaellacroix instructed, and the variables for the IF and MAC at the top, which correspond to my NIC. I assume if I did everything right, I'd still maintain internet after swapping to ngeth0, but no joy.

@schwiing etc...
I would really advise folks who are having issues with the vlan0 stripping to run virtualized under esxi. You can download a free version of esxi from vmware, and it strips off the vlan0 header so pfsense works fine on the virtualized adapter.
And you get snapshotting too, which I can attest is very useful from personal experience. I run pfsense 2.6 on a AT&T fiber connection using the supplicant method and it works just fine.
You can use it as an interim approach until the move to the new BSD codebase is completed if you want, but as I said, I find the virtualization very valuable.

I suppose I could try it...maybe with a dedicated box (spare PFsense) and install ESXi with Pfsense virtualized.
. Is there any performance loss running pfsense virtualized? Any other disadvantage? -

I've seen other people mention this too - how do you configure ESXi to do this? Does it just strip off vlan0 headers by default, or do you have to do something specific? I'm trying to do this by running pfSense under Proxmox, and I see no options to do this.
-
@schwiing I would suggest using a managed switch. Really is nice to put 3 ports in a separate vlan and get 2 public ip's (or more if you wanted) for a lab setup.
Or even a public server completely separate from your LAN or anything else you would want to do with a public IP. -
It strips it by default. I can't speak to proxmox, but esxi definitely does this.
-
I am considering doing this also...albeit it means buying another switch and some transceivers...trying to figure out which switch would be best for stripping vlan0. I'm leaning mikrotik but I'm horrible at both RouterOS and SwOS. They're not terribly difficult but it's just not intuitive to me.

-
Any managed switch should be able to.
I use Cisco SG-300's but there's plenty of posts on here with suggestions for managed switches.
Any switch that let's you assign vlans will work. -
So, if using mikrotik, how would I set it up if put in between the ONT and PFsense?
What would I change here?

@schwiing You'd have to go into Vlans first, create a new vlan. Use an obscure vlan that you won't need, like 4094 since it's the last usable vlan. Then use 2 ports, say 9 and 10, and set them both to vlan 4094. Not sure what the "force vlan ID" is but you might need to check that. Set both to enable, and untagged only.
Then plug the ONT into 9 and the WAN into 10. That's it.
If you want another public IP, set another port to that vlan and plug that port into another router's WAN.I've never used Microtik but that would be my guess. The manual would probably tell more if needed.
-
@jarhead Ah, so even the WAN port will be able to see VLAN0 (on port 9 in your example) despite it being VLAN4094? That's the part that always confused me. I didn't know if you had to trunk port 9 to accept VLAN0 or not. If they're both untagged, that makes it MUCH easier!
-
@jarhead
Oh.. One more thing. What do I set for the IP of the switch? -
@schwiing Anything you want on your subnet. That's just for managing it.
Just to be clear. You can then use ports 1-7 (or 8 if only using 9 and 10) for your LAN devices. You don't need a separate switch for this. That's what vlans do. Turns one switch into 2 or more.
-
@jarhead I was planning on putting pfsense on port 10 and the ONT on port 9. I have switches beneath pfsense so I was planning on leaving 1-8 empty. If I use those ports, how would they be routable?
-
@schwiing If you're adding a new switch between pfSense and ONT they won't be.
My point was you don't need to add a new switch if you have enough ports on your existing switch.So I have my ONT going to my port 26, two WAN ports on 25 and 27, and my pfSense LAN port going to 24.
25 -27 are in vlan 4094, then 24 and all other LAN ports are in vlan 442 (my default).
So 1 switch handles my WAN and LAN connections.So you can use ports 9 and 10 for WAN, connect your LAN to port 8, and use 1 - 7 for LAN devices.
-
@jarhead ah I understand now. My downstream switches are mostly full so I figured this would purely serve in between the ONT and Pfsense. But what you're saying makes sense.
-
@jarhead Apologies for asking again, but I'm trying to wrap my head around this before my install. If I set WAN to VLAN 4094, you're saying that will strip the VLAN0 Tag from the ONT. OK.
But for LAN, if that's also set to 4094, how will PFSense see it?
Do I need to set something on the PFsense side to accept 4094?
Does my subnet need to change from .1 to .4094 or, do I have to trunk the connection on PFsense?That's the part I'm confused on. I'm not sure how PFsense will understand how to receive 4094.
EDIT: Or, will my Global IP (That PFsense understands) become x.x.4094.x due to the VLAN tag? Is there anything else I need to set on the WAN Interface tab (or do I leave it as DHCP) or anything else on PFsense?
-
@schwiing 4094 is only a VLAN internal to the switching Netgate devices (1100, 2100, 3100, 7100) and not presented on your external network as that port is untagged on the interface.
-
@rcoleman-netgate @Schwiing And it doesn't go to your LAN, it goes to your WAN but I'm guessing that was a typo.
