How to get pfSense WAN to accept VLAN 0
-
@stephenw10 in 22.05. My thought is just that Frontier isn't using Vlan0 here. But I'm also not entirely sure one way or the other aside from the result. Is there a way for me to check?
-
I took a pcap a couple of weeks ago and the vlan 0 tag was there. I also have frontier in CT. Are you familiar with wireshark?
-
Yes, it would fail in 22.05 if they were tagging. You can run a packet capture on WAN for port 68 and then renew the dhcp lease. If you then view it at full detail you will see any tagging in the replies.

I'm familiar with Wireshark but have only run it once and that was a long time ago. I may need some help to figure that one out.
I'm sure there's some good guides on the web though. Can report back once I figure it out
-
Stephens idea is better to use pfsense built-in packet capture.
-
-
I always enable promiscuous mode to be sure but that shouldn't be required here. I won't hurt either.
-
@stephenw10 Ok. I ran a packet capture and renewed WAN + relinquished my lease. Didn't get an IP back so I had to reboot the ONT, after which I got an IP back. Stopped the capture and got a .cap file. Here's what it says (masked my IP):

-
Yes, now change the detail level to full and hit 'view capture'. Scroll down to the replies and see if there are any tags.
-
@stephenw10 Ah, i didn't set it to full before - good catch.
Apologies for the dumb question but, what does the tag look like? What term should I search for?
-
Like I showed above, here.
Where is shows
vlan 0, p 4,That's priority tagged as 4. -
@stephenw10 I don't see the term "vlan" anywhere in that packet capture. My guess (if I did it correctly) is that it's not tagged.
-
Yeah, I'd be amazed if it was and still worked in 22.05. Good to check though.
-
@stephenw10 thanks for guiding me through it.
-
I'll check my frontier 2gig service tonight and report back
-
@michaellacroix Sounds good.
-
@stephenw10 Steve, do you need me to check something? I am one of those stuck under 22.5 and working, everything else did not work as you can see in all my other posts. :-)
-
I can confirm as of this morning, College Station, TX still wants vlan0.

@cucu007 said in How to get pfSense WAN to accept VLAN 0:

You are seeing it pull a lease in 22.05?
If not it won't work there with VLAN0 without the netgraph script. You'll need to go to 2.7 or wait for 22.11 snaps (which should be any time now).

@stephenw10
I can confirm in my area frontier is still using vlan 0. Thanks
