Hi all.

Got my PS3 and tv set up at my house however my sisters bf also sometimes sets his up and we tried to play online last night and I could connect however his ps3 got stuck at "setting up game" on COD WAW.

I have set up a static ip on my ps3 and no difference.

We are using a Netgear DG834g router and I think its a 5mb/s connection from TalkTalk it usally runs at about 3.3mb/s

any ideas?

NAT issue.

No matter how many machines are on your network, the internet sees it as one machine, then the ports get sent to the right machine from your router. So PSN traffic will get sent to your router, and your router will send it to the PS3. Because it's not a normal port (like HTTP) it doesn't function well with two machine effectively requesting the same data.

There may be a way around this, check on the Sony forums.

Thats about it in a nutshell, However I dont think NAT is the problen. You get the same issue if you try and connect to Xbox360s to one router and go online, so its not limited to just PS3's. I think the issues are from the server at the other end, be it for XBL or PSN. The server at the other end cannot deal with 2 incoming connections from what is in effect a single IP/Mac address trying to do different things. For example one PS3 logs on, so PSN does its stuff, then hold on that same PS3 is trying to logon again(thats what PSN sees), so it does its stuff, sees that there is a user with that IP already online and drops/discards the 2nd connection. Most people only have 1 PS3 or 360 connected, so the situation rarely arises.

I have 2 PS3's on line at home and they both work fine at the same time.

The connection problem could just be WAW having it's usual hissy fit

That's what I meant to say

But the outbound traffic will have a different port number for each machines traffic, so it shouldn't matter that they share the same ip address.

I'd be looking at which brand of routers work with two ps3s and which don't.

i cant believe that its not possible for this to work. what have you tried ?

im not sure how techie you are but what i would do is to assign both ps boxes a staic ip in a dmz. then try each one individually to see if you can connect. it might help / work

I've got exactly the same router, and manage to share the internet connection between 2 360s quite happily.

What is you NAT setting? I think you need to leave it as open.

Well after setting up both PS3 with a static IP it now works.

Played against each other last night for a couple of hours, it did freeze up once but generally it seems to work ok with little lag.
