UPnP Fix for multiple clients/consoles playing the same game

[whiteshadow]

No fix here.

playing COLD WAR or VANGURD. Both PC players. Applied the patch and restarted pfsense box. Shows open for one and the other pc gets connecting to finally, unable to connect. I collected tcpdump collected will review

Tried on my Sons pc as well and same issue.

Trace shows conversation over port 3074 so it "seems" like it worked but doesn't always show under "status > upnp" or under states (see rst pckt so expect state to be clear).

Settings:
running: 2.6.0

System > Advanced > Firewall & NAT >
"NAT Reflection mode for port forwards" : Pure NAT
Enable automatic outbound NAT for Reflection : checked
Enable NAT Reflection for 1:1 NAT : unchecked

Nothing in "port Forwarding" for these pcs just my "calibre and minecraft server"

Firewall > NAT > Outbound
Hybrid : set
Mappings: alias name for my PC's set to static port <-- is this what is killing me?

Snip:
https://drive.google.com/drive/folders/1rPumILNl6trWzYoMOh_d-Id1dJ8_O2pC?usp=sharing

plug my netgear router and no issues.

update:
Error for Cold War: Negative 345 Blazing Gator | Which leads to port forwarding and all that

Interesting I use to see COD try and open other ports, but I no longer see that behaviour. A

update 2: Disabled and rebooted :
Firewall > NAT > Outbound > Mappings: alias name for my PC's set to static port

get strict now

@whiteshadow
as far as i know: "static port mapping" does NOT work with multiple players on the same game, even with applied patch. you should delete this manual created outbound nat rule.

for me right now, cod warzone tells me "open nat" so far so good. with anno 1800 i still get "strict nat" but possible matchmaking. i think there is somehing else wrong with anno 1800.

@m0nji
I have already moved the static port option in my "Firewall > NAT > Outbound"

This didnt resolve per update 2. just get strict on every game and pc now. Making things worse

so create a output mapping rule for every pc (for games)for ports 3074?
So we are saying UpNp is opening allowing in (even though nothing in UpNp Or states to say that is working" but im not allowing it to go out?

Anyone who has any COD game what are your settings to get both to show open? did u have to create outbound rules for each PC and if so and u didnt use static what is your NAT port?
I thought having "pure NAT" and "Enable automatic outbound NAT for Reflection" would create the outboud rule?

NOTE: removing my static rules for my PC's and now all games are strict, vs one being open and one being strict.. and nothing in UpNp anymore either and no states.

@pcross616 : what are your settings at that everything is showing as open?

In Thread: https://redmine.pfsense.org/issues/7727

@Jon8RFC . : Did you have to create outbound rules?

[whiteshadow]

Looking into game "Pummel Party" u can hoist and choose a port to use. So I went ahead and launched game on both pc's and tried creating a match. It only worked on pc and teh nother never saw the state for the port show or in UpNP.

If I go to game and change port from 14242 to 14243 then both pcs show up. It seems it wont allow to clients using the same ports. It seems like the same issue as before, not sure what fixed but none of my games can we have more than 1 person playing at a time.

Please share how your configs are that allow multiple games using the same port to work?

both pc's using same port:

Telling the another pc to use another port for same game (game thankfully gives me this option) :

@rivageeza : I see you tested with COD and it uses the smae port 3074, what does your UpNP status show when both are running and showing open? What is your config look like? are you using "pure NAT" ?

Going to disable "hybrid" and try "automatic". Rebooted after this change and still every pc is STRICT..

[rivageeza]

Had already tested the patch with Call of Duty Warzone, PC and PS5. Post patch we both get open NAT, can join the same lobby and play in the same game. Both platforms are using port 3074.

Saw some people having difficulty with PC and PC, I've just finished testing and happy to report the fix is working for this configuration too.

2 PC's on the same LAN, both playing warzone using 2 different battle.net accounts, both open NAT and was successfully able to start a duo and loaded into a game together. Again, both PC's used port 3074.

@rivageeza : What are your settings?

[jimp]

If it's not working for someone, first check that the patch is actually applied. This is what it should look like in the system patches package:

Next, check the ruleset and make sure the nat anchor is there:

$ grep miniupnpd /tmp/rules.debug
binat-anchor "miniupnpd"
nat-anchor "miniupnpd"
rdr-anchor "miniupnpd"
anchor "miniupnpd"

If you have more than one WAN, make sure UPnP is using the same WAN the clients exit.

[whiteshadow]

@jimp : Only one WAN

[iculookn]

Not related to multiple devices/games, but I applied the patch, removed static port mappings and changed outbound mode to automatic and I can still get open NAT on XBOX.

well done to all involved.

[whiteshadow]

@iculookn : what are your setting for this:
System > Advanced > Firewall & NAT:
NAT Reflection mode for port forwards ?
Enable NAT Reflection for 1:1 NAT ?
Enable automatic outbound NAT for Reflection?

[iculookn]

@whiteshadow
System > Advanced > Firewall & NAT:
NAT Reflection mode for port forwards ? DISABLED

Enable NAT Reflection for 1:1 NAT ? UNCHECKED

Enable automatic outbound NAT for Reflection? UNCHECKED

[whiteshadow]

@iculookn :

Thank you for posting those settings. I went ahead and applied them and rebooted pfsense, and boom it all works all is open.

Currently NAT is set to automatic and then the above settings iculookn pointed out. With those set it seems this patch fixes the issue.

thank you for the fix, and think this piece should be documented. Even though it sounds like a bug to me, when "pure NAT" enabled upnp doesnt work as expected.

"pure nat" disabled and it works perfectly.

@marc05 said in UPnP Fix for multiple clients/consoles playing the same game:

@donzalmrol That's certainly odd. Try rebooting the computers/pfSense and then test again. Make sure to remove any manually added Outbound NAT rules.

It seems that I have now a different issue when I upgrade to v2.6.0
https://forum.netgate.com/topic/169884/after-upgrade-inter-v-lan-communication-is-very-slow-on-hyper-v-for-others-wan-speed-is-affected/16?loggedin=true

So I'll test the UPNP again once my main issue is resolved for Hyper-V.

[whiteshadow]

Yea there be some oddness going on. As we switched from Cold War to Vanguard and all the upnp went away for our PC's and we are all strict again. If we switch to Cold War again we are strict.

rebooted pfsense box again and all 3 PC's and still all strict.. Really strange switching game types breas it and then after everything rebooting.. still no resolve. really odd

@DonZalmrol : What are your outboud settings like? automatic or hybrid? what is :
System > Advanced > Firewall & NAT:
NAT Reflection mode for port forwards ?
Enable NAT Reflection for 1:1 NAT ?
Enable automatic outbound NAT for Reflection?

my settings:

[whiteshadow]

Upgraded to 22.01: rebooted, reinstalled the patch and rebooted after install.

Seems to have resolved my issue.

[rivageeza]

@whiteshadow My settings are as follows.

"pure nat" disabled and it works perfectly.

I tried last night without success, but when i disabled "pure NAT" and rebooted firewall. It says open nat in Warzone/PC, but in PS4 it says NAT type 3 and not type 2 for some odd reason.

[whiteshadow]

@coraze
can you post matching screenshots that I posted above covering settings

[whiteshadow]

@rivageeza
hmm so u have outbound like i did with alias with static set... Then u have 1:1 with pure NAT while i didnt...

I want to try that, but I have 2 out of 3 PC's showing OPEN. Third always strict... might change to what I had before and add the 1:1 for the pure NAT..

reinstalling on 3rd pc as it was DEV channel windows 11 and couldn't get it working... waiting for small game "cold war" to download to test

-- tested and its working on 3rd pc with "Cold War"

• Haven't changed back to similar settings as @rivageeza : yet

[jimp]

Interesting the the NAT reflection options appear to make a difference. I wouldn't expect that to be a factor unless there were also port forwards or 1:1 NAT which overlap what UPnP is trying to do. Something in the reflection rules must be redirecting the traffic as it enters the LAN, while the UPnP rules would only translate traffic as it exits a WAN.

Would be nice if we can narrow down which of those options specifically is interfering and if it is related to port forwarding. If there is a potential for conflict there we can add it to whatever docs we make to cover this.
