DNS server from pppoe does not work with 2.0.2

jimp

The interface status page doesn't have the smarts to split up the DNS servers. They always show up on the "wan" interface.

They always show up on the "wan" interface.

Ok, but why "Allow DNS server list to be overridden by DHCP/PPP on WAN" do not work?
Work fine on 2.0.1 with three pppoe connections (6 dns server).

jimp

I don't know. I didn't specifically test pppoe on mine at home with 2.0.2.

Hi,
I am having the same issue with 2.0.2. I switched my slice mack to 2.0.1. Nothing else changed in config. pfSense is not getting the DNS servers from the PPPoE connection…

Regards,
Alexander

Alexander, did you have one or more pppoe connections?

jimp

Do you have anything showing up in /var/etc/nameserver_* ?

slu

[2.0.2-RELEASE][user@pfsense]/var/etc(7): ls -l | grep nameserver
[2.0.2-RELEASE][user@pfsense]/var/etc(8):

No such file.

Bentrax

@slu: only one connection

@jimp: I didn't look in that file, I only locked at the interface status page and there was only 127.0.0.1 the local host as DNS. May the content of that file be different, then I will switch slices again and have a look…

Install the System Patches package, then fetch/apply this patch to see if it helps:

Sorry not enough time atm to play around… maybe slu can test...

Thank you very much, it work now!
Pfsense 2.0.3 release now?

I must remove the patch before I upgrade to the next version? How to handle it?

jimp

The patch won't reapply itself so it's safe to keep as-is.

There may need to be a 2.0.3, hard to tell just yet.

It is dangerous to upgrade a remote pfsense with pppoe wan connection to 2.0.2, the system can not reconnect without dns server to my openvpn server.

jimp

Only if you have not manually defined DNS servers.

Bentrax

So the solution for me is to note the DNS servers now, then switch slices, enter the DNS server manually, install the package and the patch (think I can't without DNS, won't find the servers), then remove the manual DNS servers?

I think I'll wait for the next maintenance release…

jimp

Or just define custom DNS servers (like 8.8.8.8 8.8.4.4) and don't use the ones from PPPoE.

chpalmer

Yep- I did the upgrade at my office remotely and had no problems. I had defined dns so did not run into this.

timur_dav

Run into the same problem while doing remote update… Had to specify DNS servers manually. I want to see release without need to patch. Expecting quick 2.0.3

shenrich

Had the same problem. The patch solved it. Due to the possibility of locking yourself out when doing the patch remotely, I would prefer a version 2.0.3 of the upgrade too.

Thanks for the great work

There likely will be a 2.0.3 but it may not be immediately, in case someone finds a similar bug in the next few days we don't want to end up having a 2.0.4 so soon either :-)
