Hello,
An user with ePMP 1000 on SM kindly informed me that he's having some issues on online gaming on PS4. Connection speed works fine, it is also stable . The problem comes with the following game, "Destiny 2". The problem consists of being costanly kicked from the game with a networking error called "cabbage".
By doing a quick research, actually this problem affects a lot of people with differents operators, some of them fixed by setting their connection on PS4 with NAT Type as "1" (open). User NAT Type is 2 (moderate).
However, an user that works for an ISP wrote on their forums that the error is caused by the ALG (application layer gateway) also called application helper.
To be more specific, the CONE(UDP) connection helper which is bound to UDP port 3074. Actually, it seems that by accessing via telnet on default gateway, it was possible to fix it by unbinding it from port 3074.
Now the problem is, that on ePMP maybe this isn't possible, since the commands via telnet are different, or, I don't find anything that can do this "unbind" trick.
Hope you can help me in someway.
