This is always CONSISTENT on my CGN3 while testing internet setting on my PS3; When testing the internet settings the UPnP always appears to be unavaliable....... Due to that, I can't join online sessions (e.g GTA V Online) and is why I cannot join servers properly in BF4.
Solved! Solved! Go to Solution.
When you see it’s unavailable it means it’s enabled at both CGN3 and PS3. If it not enable then you would get error – it’s disabled.
Technically, it seems PS3 is not able to open the ports required for GTA and BF4. You may want to obtain the ports required and do the port forwarding manually.
Let the community know if you need help in port forwarding, all the best
Thank you @RogersMoin and @Datalink for your help so far! 🙂 When doing the UPNP test it says that it did not respond to their UPNP probes which means that it is good news. I was surfing the web for situation similar and apparently, in a separate forum, Gdkitty said that the problem was because the CGN3 has more strict firewall.\
sidenote: when Gdkitty was saying the stuff about a more strict firewall on the CGN3, he was comapring the CGN3 to the Cisco DPC 3825.
Thats an interesting result. Not what I expected to see of course. I had thought that with UPNP enabled in the CGN3, the test would fail as it would have shown active or enabled. The result might make sense though depending on the Firewall Security Level. There are three settings, Maximum, Typical and Minimum. You can also define a custom rule set. If your firewall is set for Maximum or Typical, maybe the result makes sense. If its set for Minimum, then RogersMoin indication to set Port Forwarding for GTA might resolve the issue. Port Triggering might work as well, so it might be worthy of an experiment.
Thank you guys 🙂 I will try to port forward based on this page and notify you guys with the results: http://portforward.com/english/routers/port_forwarding/HitronTechnologies/CGN3/PS3_Grand_Theft_Auto_...
edit: After port forwarding I did the internet settings test on my PS3 and it says that the UPNP is unavailiable and the NAT type is TYPE 2. I haven't tried joining a server yet, so let's hope it works 🙂
The router is running in Bridge mode, or the modem is running in Bridge mode? You should see pretty reasonable performance with that router. Can you describe how you had it connected to the modem? CGN3 or CGN3ACR in bridge mode, connected from one of the LAN ports to the WAN port of the TP-Link Router, with the router running in full router mode?
