How to get pfSense WAN to accept VLAN 0
-
@stephenw10 Have we made any additional progress on getting this issue fix permanently for those of us using Fiber (AT&T and Frontier)?
-
No. One of our staff uses pfatt and he tested it in a 2.7 snapshot but hit other issues trying to run the script there. The way netgraph handles opening connections changed.
The script here though doesn't require any of auth stuff that pfatt does, it only creates VLAN0 tagged traffic so may work, I haven't heard either way.A better solution there would be to just add priority tagging to FreeBSD. That's not immediately straight forward though because of the security implications.
In order to upstream something like that we would need clear evidence of a real world use case so the more people who can add their names to the open bug report for this the better.

Try to put pfsense into a VM and run VLAN tagging on the WAN interface using VLAN 0.
Then see if it works.

@stephenw10 I can confirm it doesn't work in 2.7 on both igb0 and em0.
I did a clean install to 2.5.2 confirmed everything was working and then upgrade to 2.7.0. (Note: After the upgrade, it asked me for my default WAN and LAN again which were already set to igb0 and em0.)
Received the following error on both when running the vlanzero script:
===groupFatal error: Uncaught Error: Call to undefined function pfSense_ngctl_attach() in Command line code:1 Stack trace: #0 {main} thrown in Command line code on line 1 === -

I hope we get some pfsense developer to work on this prior to 2.7 release. I miss working under 2.6 and would hate to go back to work under openwrt, pfsense is my favorite FW.

There is no longer any need to attach the interfaces like that. You should be able to just remove or comment out these lines from the script:
echo -n "$(getTimestamp) attaching interfaces to ng_ether... " /usr/local/bin/php -r "pfSense_ngctl_attach('.', '$ONT_IF');" echo "OK!"See: https://github.com/MonkWho/pfatt/pull/73/commits/015a8cf91340699fc18f1f54eeef3160e8c2ee9e

@stephenw10 I removed those lines, and I'm not getting the errors anymore. But I don't have any internet.
-
But the script appears to run though and the netgraph interfaces are created?
Are you able to see any and tagged (or untagged) traffic in a pcap on the parent NIC?

Hi Steve,
Did we make any progress last week on resolving this issue for 2.6 and perhaps 2.7? -
Not beyond what's shown here. The script need to be altered to remove the nfctl_attach lines since they are no longer needed. We have one report that it doesn't work still but no packet captures that might show why.
-
Its hard to think that many of us are still dealing with this nighmare of accepting traffic tagged on VLAN 0 at the WAN interface.
Can we please get some traction this item? My $20 bucks router from walmart is able to work just fine, how is it possible that this expensive piece of equipment is not able to get this working under release 2.6.x or 2.7.x, many of us were able to get this working using some hacky way under 2.5.2. Please lets figure this out.
-
There are workarounds. It depends what your ISP actually requires.
If they are sending priority tagged replies to dhcp requests you can just use a switch to strip those tags.
If you need to send and receive priority tagged traffic then you still need the netgraph script to do that and something in the iflib based Intel drivers has broken that. So you ca try using the non-iflib driver or use a different NIC.

Thanks @stephenw10
This post saved my bacon. I have frontier fiber and need the script to obtain an IP on the wan interface due to the vlan 0 issue. When I upgraded I got the same error messages as above and this fixed it for me.
-
Just commenting out the lines from the script?
Can I assume you are using a NIC other an Intel e1000 device? Other NICs should work with that.Steve
-
yep, just commenting out the lines worked for me. Yes, my nic is not e1000 device. The script broke upgrading from 22.01 to 22.05
Upgrading form 2.6.0 was no problem
Upgrading to pfsense 22.01 no problem
Upgrading from 22.01 to 22.05 the script broke with the error message:Fatal error: Uncaught Error: Call to undefined function pfSense_ngctl_attach() in Command line code:1
Stack trace:
#0 {main}
thrown in Command line code on line 1 -
I am using e1000 NICs, are there any solution for those of us or we are to remain in the dark?
-
I wouldn't hold your breathe. Technically its a freebsd shortcoming and pfsense should address it. Negate is basically saying they can do without all the att, verizon, frontier, and all other ISP's that use the vlan zero tag. What a shame. Theirs only a small group of users in this predicament who are technically efficient enough to implement these scripts and changes.
-
This is very sad to hear considering that a $30 walmart router can work just fine with the VLAN 0 from frontier. I also tested using openwrt and those are working fine, but pfsense has been my favorite FW and I would dearly miss it to replace it with something else. I am optimistic Stephen and the team can get something going for those of us using e1000 NICs.
-
yep, i moved on to different hardware..

@michaellacroix What hardware you using now?
