Seeking for help about UPnP issue. (PS4 Gaming GBONEXT)

[RX-78]

To All Friends,

Thank you for reading my post.

My issue is, why sometimes my UPnP rules are not correctly generated.

I'm a PS4 player who mainly play Gundam Battle Operation Next.

Normally, from openning PS4 until I login the game, it will generate 3 different UPnP rules.

1. UDP 9308

This one usually appears after I tested or retested the networking of PS4

2. UDP 9305 & UDP 9306

They appear when I am logging in the game

However, sometimes I can never have 9305,9306 and 9308. All I have are randomly generated UPnP rules whish will have bad effect on gaming.

I asked other players, when you have UDP 9306, the networking during the game is the best and the most stable one.

Reboot PS4, reboot router, clear and reopen UPnP have no use.

I have to wait, sometimes 2-3 hours and things goes normal again.

Is this the problem of my ISP, or I should do some settings?

If somebody had ever played the game, you will know the game needs strong networking.

If you disconnected during the battle it will have penalty.

Wish you guys can give me some help

Best regards

How do you know that they are bad rules?  The game could be opening additional ports for receiving other traffic.  How fast is your Internet connection?  Maybe it can't handle all of the traffic required to play the game smoothly?

Anyway, you can try disabling UPnP and just go with port forwarding.

If UPnP is not working reliably for you, then you can set up port forwarding rules for those ports.

Note: Set NAT to Open in WAN Setup on your router.

Firstly, thank you so much for your answer.
However, I still have questions after reading your answer.

I`ve set UDP 9306 in post forwarding rules, meanwhile UPnP is not closed.
If UPnP goes bad, my networking still choose bad UPnP rules, not the 9306 I`ve set in post forwarding rules.

Shall I close UPnP if I wish to use post forwarding rules?
I understand that UPnP rules are automatically generated which can not been controlled.
Can I consider post forwarding rules as "fixed UPnP rules"?

If yes, then I think I shall close UPnP and own a everlasting UDP 9306 port.

Can you provide examples of bad UPnP rules?

UPnP is convenient because it's automatic but if it's not working for you, then turn it off and go with port forwarding.

Examples of bad UPnP rules:
UDP 60304
UDP 62285
UDP 54408
UDP 57640
UDP 50509
UDP 59846

They just come from no where, the ip address they serve is the ip of my PS4, they appear sometime when I am logging in GBONEXT, sometime during the game!
They did nothing but mass up my game play. They slow down the log in, player matching and cause disconnection.

Again I appreciate your continue attention to my post.

I can not explain why those UPnP rules are bad, but I know if they appear, my gameplay sucks.

Anyway, if I continue asking here about a specific UPnP port is not wise, I shall ask the game company about it.

Thank you so much for your answer!!!
