IPSEC ERROR while creating private multiplayer session

I believe that is a superhub 2 , this is from the "known issues" page...

Known Issues

This Gateway will sometimes cause issues connecting with cloud based games, resulting in a timeout with "Unable to join session" status message. This is due to the Gateway being configured to disable IPSec Pass-Through by default. IPSec Pass-Through is required
to establish multi-player sessions. To resolve this issue, you must enable IPSec Pass-Through on the Gateway..

There is a current known issue where the SuperHub 2 will cause constant disconnections in multiplayer-based games if on Wireless.

The issue is currently being investigated by Xbox and Virgin Media.

Super hub 2 are known for this very issue on wireless , this is from the page on that router ....

if wired is not an option , you will probably need a different router ....

Are you able to join someone else's Multiplayer game, can they invite you?

Is it possible, that you are participating in a private lobby that someone else created, and the game won't allow you to invite someone?

What game are you playing exactly, and are you the one that initiated the Multiplayer session?

The best way to get into the multiplayer game is to go to single player first then to multiplayer private. Once in private session, transport to Mexico then join regular multiplayer. One of the reasons it is difficult to fix the game is because the sessions
keep getting corrupted when people transfer to new sessions after being in a infected session. If you see someone getting a lot of xp points at one of the hideouts you need to kick them. You can also try starting a private session then invite others to your
session but have them leave the game first then when they join your session they restart their game fresh. I cannot guarantee it will work all the time, but it will sometimes. You can also go to public sessions then shut your game off. Restart your game in
a private session and send invites with those instructions to your recent players list. Just don't let anyone into your session straight from a public free roam. That should keep your session clean and fun. Good luck and hope to see you all there. I love this
game.

The Superhub is the problem here , they are notorious for disconnections while using wireless....you may have luck if you hardwire it , but I would get a separate modem and a cheap netgear router....this issue seems to just pop up , some say theirs is fine
, most others not

you can try this below as a few said it has helped but I would toss it....
