The case with UPnP setup? @vMACUnder firewall rules, make an IPv4 allow LAN to any rule with the advanced option checked "Allow IP options". Test again after and see what happens. @Marc05 said in Test Request: UPnP Fix for Multiple Consoles playing the same game / static port outbound NAT:@vMACUnder firewall rules, make an IPv4 allow LAN to any rule with the advanced option checked "Allow IP options". Test again after and see what happens.Still STRICT You tried playing the game?Try following the steps in this guide: test again, first without the outbound NAT rules, and second with them. Make sure the test involves playing a game, and not just doing a network test in the console. Upgraded today to 2.5.0DEVELOPMENT and getting this error miniupnpd 80987 setsockopt(udp, IPV6_RECVPKTINFO): Invalid argumentAfter looking at the redmine, it did't look like i needed to update miniupnpd.Any ideas or more info needed? Tested today with a base installation of 2.5.0DEV and two PS4s.Base config, just UPNP enabled and Pure NAT.I get NAT Type 2 on one console but always type 3 on the second.I can see the following:miniupnpd rules/nat contents:nat log quick on ix0.10 inet proto udp from 10.XX.XX.XX port = 9308 to any keep state label "10.XX.XX.XX:9308 to 9308 (UDP)" rtable 0 -> XX.XX.XX.XX port 9308rdr pass log quick on ix0.10 inet proto udp from any to any port = 9308 keep state label "10.XX.XX.XX:9308 to 9308 (UDP)" rtable 0 -> 10.XX.XX.XX port 9308So UPNP seems to be working but for some reason only allowing one console, any additional debugging I should do here? It seems that static ports on outbound NAT is still necessary. Make sure to create that rule as well. @Marc05 static port NAT is a workaround, and not a nice one.The implementation we hope for is that two.

Been fighting with it for days. Lightbulb42, Feb 24, 2014 #6.Every web services must run on a port or else the service will be inaccessible. For example, when you visit a website, your web browser automatically connects to the web server using port 80 because that is the standard port registered in the IANA organization. It is also possible to configure a web server to run under a different port number such as 8080 and since the web browser connects to port 80 by default, you’ll need to instruct the web browser to visit the URL using the different port by adding the port 8080 at the end such as if you are trying to host a temporary game server, connect to a CCTV, remotely access your router configurations, download media files using a BitTorrent client such as uTorrent, all of the actions mentioned above requires an open listening port for optimal usage and in some cases it won’t work at all if the port is closed.Fortunately most modern routers already support UPnP whereby the router automatically opens and forwards the required port when it is triggered by the software, saving you the trouble of manually accessing your router settings to forward a port. The only problem is, how do you know whether the port forwarding either manually created by you or automatically through UPnP worked? Here we have 5 web services which you can use to test if the forwarded port is open or closed.1. YouGetSignal Open Port Check ToolThe open port check tool by YouGetSignal is a fast and easy to use port forwarding tester. Upon visiting the website, it detects your external IP address and automatically embeds it to the remote address box for your convenience. You can find a list of commonly used ports at the right hand side and clicking on it will instantly check the status of the selected port. You can also quickly scan all of the provided common ports by clicking on the “Scan All Common Ports” located at the end of the list.Visit YouGetSignal Open Port Check Tool2.

UPnP is intended primarily for residential networks. No special device driver support is necessary, common network protocols are used (TCP/IP, HTTP, XML, SOAP). UPnP uses UDP port 1900 and TCP port 2869.The UPnP technology is promoted by the UPnP Forum. Formed in October 1999, the UPnP Forum is an industry initiative of more than 1000 leading companies in computing, printing, networking, consumer electronics and home appliances. A huge library of UPnP resources is available at the website of the UPnP Forum.UPnP was published as an international standard, ISO/IEC 29341, in December 2008.The foundation for UPnP networking is IP addressing, either by DHCP or by AutoIP (zero configuration networking). The next step in UPnP networking is discovery, based on the Simple Service Discovery Protocol (SSDP). SSDP allows a device to advertise its services to control points, for example to media servers (Serviio) on the network. The next step is to learn more about the discovered device and its capabilities by retrieving the device’s XML description from the URL provided by the device in the discovery message. Now the control point can send actions to a device’s service using the Simple Object Access Protocol (SOAP).An additional capability of UPnP networking is event notification, or eventing. The event notification protocol defined in the UPnP Device Architecture is known as General Event Notification Architecture (GENA). The final step in UPnP networking is presentation, usually by providing an URL of a webpage loaded in a browser.UPnP AV is an audio and video extension of UPnP, referenced in specifications published by other organizations, including the Digital Living Network Alliance (DLNA).Problems with UPnP are lack of authentication and vulnerabilities with the risk thatUPnP Certification Test Tool Download - UPnP
@Marc05 Thanks for getting back so quickly.I do have multiple Xbox Ones with the same game (note that some people including myself have been having issues with Ghost Recon Wildlands) and some time to provide some testing. My knowledge is not 100% but I can certainly give testing ago.Before I upgrade to v2.5 can I just confirm how best to conduct the testing:I have successfully gained Open NAT via the use of Outbound NAT rules and static ports as well as UPNP ACLs. My xboxes are contained within their own specific VLAN.Do I just need to remove all UPNP ACLs and Outbound NAT rules and then test to see if I get open NAT across consoles as well as seeing if I can play online in games I have previously had problems with? @jonathanjadamsIt's important to first get a baseline of what works/doesn't. The basic configuration that should be currently in place is:System / Advanced / Firewall & NATNAT Reflection mode for port forwards: Pure NATEnable automatic outbound NAT for Reflection: CheckedFirewall / NAT / OutboundRule with the following: Interface: WAN | Source: Alias with console IPs | NAT Address: Interface IP | Static Port: CheckedFirewall / Rules / LAN (or whichever interface the consoles are on)Rule at top with the following: Protocol: UDP | Source: Alias with console IPs | Destination: Any | Allow IP options: CheckedServices / UPnP & NAT-PMPEnabled with UPnP & NAT-PMP both checkdExternal Interface: WANInterfaces: LAN (or whichever interface the consoles are on)Default Deny: CheckedACL: (e.g.) allow 0-65535 10.0.5.0/24 0-65535TestAfter these settings are set, power off the consoles, reboot the firewall (to clear states, old mappings, and ensure a control state for testing), then power on the consoles. Now test the same game at the same time on two consoles.Does it work?What is the output.
