Never had problem with any hub currently hh2 or other devices though I don't change settings from when its lifted from the box just to suit a poorly put together online game experience. You wont convince many as Bt and Sony xbl and PC's have this master plan to ruin its customer base.
Same problem as the original poster...
HH2. Win7 on a relatively modern PC. COD MW3 NAT type Strict and cannot change it no matter what I do.
I've tried just about all the sensible 'fixes' that I've come across on the web (including this place!) and had no luck whatsoever. I have 3 friends all with HH2s and all 4 of us have the same problem... which leads me to think that it's certainly a HH2 issue.
As previous posters same problem withMW3 on PC Nat strict tried all the suggested fixes but to no avail been in touch with BT Tech desk they suggested trying PF Config already been there done that worn the t-shirt reckon next thing is toi take A Big Hammer to the dam thing.
I have the same problem however i managed to fix it just now. give it a try and let me know if it works. The way to open your nat is to set 3 different port forwarding's to your home hub 2 for your ps3/xbox 360. first you will need to know the mac adress if you havent assigned a name for the console. then apply the 3 different port forwarding the three that i put in was playstaion 3, XBOX live and Call of duty. i then reset my router and bam i have an open nat type. Im not sure if the XBOX live one is needed as im using a ps3 but even with all 3 assigned it opened up the nat type. I do have a static ip adress so assign a static ip adress before attempting let me know if i have solved this problem
YES! I tried your method, thinking it wouldn't make a difference after changing settings on the hub and PS3 for countless hours, but I can't believe its worked. I registered to this forum to thank you.....
....Although, It hasn't been tried and tested and I have yet to see if I can host parties on MW3, but so far, so good.
Just for fun, I thought I'll try another router I have (dlink-2680).
You plug the cable in, put in the bt username, enable upnp.
MW3 nat type now: OPEN (was strict before).
This is how it should be on home hub 2 😞 No messing about with dmz, open ports etc... upnp sorts it all out.
