Getting an Open Nat for xbox live

[theevilnarwhale]

In the apartment I live in we have 3 xbox 360s. We have been trying to do open nats for all of them, but because you have to open up the specific ports of 88 and 3074 we are unable to do all three. Are we doing something wrong? Can ports not be opened up for multiple IP addresses?
fyi: router is NETGEAR WGT624v3

Static IPs, or DHCP? I know it's dumb, but despite having it set up properly, having a static IP on my 360 screwed with NAT, and switching to DHCP for it fixed things.

EDIT: Nevermind, I need to read posts closer. For your problem... I dunno. Port triggering would allow the ports to be dynamically forwarded to an IP, but that would only work if only one XBOX were in use at a time.

You can't have the same port pointing to multiple IP addresses, no. You might have some success setting up a DHCP and UPnP so they might be able to specify whatever ports they want to use.

I'm googling DHCP and UPnP and I am just getting more confused. Can anyone shed some light on this situation?

on my wrt54g me and my roomate have been able to hook up two xboxes successfully, and play online together. I've got default settings using DHCP and UPnP.

DHCP is a method of leasing IP's to clients that is automatic and doesnt require you to go into the router and set up someone's IP every time you hook up a new machine.

UPnP is sorta tricky
first, think about what a router is, it sits inbetween your computer and the internet, when data comes from the internet it has to figure out who it's supposed to go to. Sometimes you want the PC to provide a service over the internet so that someone can come knocking and your computer will reply. usually to do this you would have to set up port forwarding, so that the router knows, if data comes accross port 2345 that computer A should get the data. UPnP allows a computer to ask the router to set up temporary forwarding for it, so that you dont have to go into the router and manually set it up.

We are able to play online together no problem, Its just that we have a lot of trouble connecting to games sometimes. Unless a game just came out it can be pretty difficult to find a game. We are just trying to find a solution.

UPnP is the devil as far as I'm concerned.

it's fantabulous when it works right =D
I do reccomend looking into updating the firmware of your router if you have issues with it. But as always when updating firmware, be very confident you've got the right upgrade version.

UPnP looks like the key to your problem.

My network knowledge is limited but try a search for "multiple xbox UPnP".

My problem with it is from a security and engineering perspective. I don't like it.

yeah there is that, but i'll be damned if I cant stand constantly tweaking forwarding on the router :P

So going into my router and turning UPnP on should do the trick? Thanks for your help guys I really appreciate it

UPnP is the devil as far as I'm concerned.

They fixed most of the Live UPnP issues a dashboard or update two ago. With up to date firmware on a non-shit router it should "just work".

I don't see the security issue. If they are on your internal network they are already "inside". Then again, I don't run a wide-open wi-fi network. If I did and I still wanted to try to put some security around UPnP I would filter protocol based upon IP and only let "trusted IPs", which would be static, to use any/all ports. Any trusted host would be locked down to the basics like http/https, etc.

Ultimately, it seems to me that your security has to already be compromised for UPnP to make it any worse.

So far its looking like it didn't do the trick. crap.
