UPNP broken on 21.05?

a_wein

Hi,

it seems UPNP is broken on 21.05-RELEASE.

I'm unable to see any active sessions from my PS5 and games fail to connect.

Logs:

On what platform?

It works just fine for me on 21.05-RELEASE on multiple amd64 devices, but I haven't checked on some of the others.

Sorry - forgot to mention I'm using a SG-3100

jimp

I do see that error on an SG-3100 in my lab, but it's not a great test there since it has a private WAN so may be failing for other reasons.

What are the exact settings used in your UPnP configuration? Either a screenshot or the contents of /var/etc/miniupnpd.conf would be helpful.

Do you have an address set for the Override WAN address?

a_wein

Very basic config. WAN is public with dynamic IP via PPPoE so I don't have an "Override WAN address".

/var/etc/miniupnpd.conf

ext_ifname=pppoe0
port=2189
listening_ip=mvneta1.32
secure_mode=yes
presentation_url=https://192.168.32.1/

OK, I tried it on a few different systems and the only ones which fail are 32-bit ARM (SG-3100 and SG-1000). I opened a Redmine issue for it:

@jimp Thank you!

I'm a bit disappointed that something like this happens on a release version and on quite popular official Netgate hardware without being noticed by pre-release testing.
I hope that the fix will not have to wait until 21.09. Unfortunately, it seems like Netgate tries hard to steer people away these days.

Prior to upgrading I never had any issues, but ever since this upgrade my logs are filled with the following:

Jun 15 16:31:36 miniupnpd 98249 Listening for NAT-PMP/PCP traffic on port 5351
Jun 15 16:32:30 miniupnpd 98249 could not find redirect rule to delete eport=3074

Jun 15 16:33:48 miniupnpd 98249 ioctl(dev, DIOCGETADDRS, ...): Device busy

The error about port 3074 is of my xboxes. If I want an open NAT, I have to flip the port every time I turn my xbox on. Otherwise it stays moderate. This was working fine before the upgrade.

I also see this constantly:

Jun 15 16:31:36 miniupnpd 98249 setsockopt(udp, IPV6_RECVPKTINFO): Invalid argument

on a 3100?
https://redmine.pfsense.org/issues/11995

behemyth

@steveits Yep, that would be my problem. Is there an ETA for when this will get fixed? I have to imagine this is a huge problem for a lot of people. I work in Networking so I can build port-forwards, but I have to imagine there are a lot of people that don't know how, or don't want to.

bcodd

Yup, I'm seeing the same thing. Disappointing after spending 400 bucks on the appliance only to no longer be able use this basic feature...... :(

jimp

I merged together two threads about this since it's the same issue for both.

We are aware and have been actively working on solving this and other SG-3100 issues.

For those who are affected, was this working on 21.02.2?

behemyth

@jimp Yes. I had UPnP sessions on 21.02.2.

When I upgraded to 21.05 it stopped working.

behemyth

@bcodd Just make manual port forwards. It's pretty simple using the GUI. I manually port forwarded my Xbox and its been working fine.

You'd be pretty surprised how much stuff doesn't need UPnP. I disabled the service and now all my iphones currectly use wifi calling too.

I think this is causing my SG1000 router to hang...

jimp

It looks like this may be from a change in the FreeBSD kernel between versions that required a new build of miniupnpd, but the version number of miniupnpd didn't increase so it didn't get reinstalled.

You should be able to fix this with:

killall -9 miniupnpd
pkg upgrade -fy miniupnpd

And then click Save on the miniupnpd settings. Or run the pkg command and reboot.

@jimp Appears to be working :) I have now got rules being created.

It'll be interesting to see if my router hangs in a few days time.

Thanks.

sdm900

there still appears to be a problem.

miniupnpd is still using a LOT of cpu time - doing AFAIK nothing.

I restart it and everything goes back to normal.

behemyth

@sdm900 Are you running 21.05 or 21.09?
