2 Xbox's 1 Router - Solutions

I'm guessing it requires multiple IP addresses from your ISP. People using NAT port forward to the internal IP of the xbox and you can't port forward 1 port to 2 internal addresses from the 1 external IP simultaneously.
That may be true if you have to manually open ports and forward them to a single IP but if the router supports UPnP then it will NAT traffic back on the relevant ports to the right Xbox.In plain terms, make sure UPnP is turned on in your router and set the consoles to auto everything. It should just work.

woosh!English?
People with ADSL routers connected to that real address use NAT (Network Address Translation) to provide their home network with the ability to have more than 1 device use the internet. NAT works by assigning multiple (private - not valid on internet) IP addresses to the kit on the home network.
You end up with 1 external IP and lots of internal IPs (generally in the range 192.168.1.1 - 192.168.1.254)
When something wants to talk to the internet the router keeps a record of the internal address of the request and then recreates the request with the external address ( the valid one) and sends it on to the internet. When the reply comes back it comes back to the external address of the router which then using the records it has it figures out which internal address requested the data in the first place and recreates the data on the internal network for your PC or whatever to pickup. Its slightly more complicated than that but its roughly how it works. This is fine for outgoing stuff that was initiated from inside as the router will build the table of source and destination request dynamically.
You get into trouble when a packet of data arrives at the external side of the router which wasn't initiated from inside. The router has no entry in its table to say which PC/network device its destined for (XBOX live does this amongst other things MSN etc). You need to setup some rule (port forwarding) in the router that basically says if you get a packet on port x then forward it to the internal IP x.x.x.x on port x. These rules can be set manually or you can allow UPNP which basically allows devices to automatically ask the router to setup port forwards that they require to work.
The problem the OP has is you can't forward the same port number to multiple internal IPs simultaneously. So you need multiple external IP addresses
external1 port 3074 to internal 1 port 3074
external2 port 3074 to internal 2 port 3074
would work
Hope thats english enough for you

according to MS, XBOX live requires UDP 88,3074 and TCP 3074. You can't have both XBOXs at the same time having those ports forwarded to them from a single external IP address.

except I think both xboxen will fight over the same port number. UPNP is just an automatic port forward request instead of the user manually setting it up.In plain terms, make sure UPnP is turned on in your router and set the consoles to auto everything. It should just work.

True, but I still think it will work with DHCP, NAT and UPnP enabled. I can't believe they wrote the software in such a way that only one 360 can be used on a private network. That would be short-sighted in the extreme, no other sensible application works that way. I'll stand to be corrected but it will scupper some plans I had for a 360 get together on an office LAN sometime.http://support.microsoft.com/kb/908874

do you run UPNP on the router?
do you run them both at the same time?
do they both show OPEN on the NAT when they are connected at the same time?
You can do some stuff on XBL even if it show MODERATE or STRICT. Theres a table somewhere but can't find it at the moment. Might be you can't host a game unless it OPEN????

Used to be moderate (according to halo3) and i have had 2 xboxs playing halo3 at the same time quite happily, either playing on the same game or playing on 2 seperate games. I was able to host games no problem (i guess this would have requested port-forwarding to accept incoming requests).
I now have one xbox in a DMZ (just for experimentation) and again, no difference in quality and no connection restrictions at all.
To make matters more interesting, i have 2 routers connected back to back, again, no issues (i have good reasons for doing this btw).

Multiple addresses from ISP (does a router not eliminate the need for this anyway ?), NAT port forwarding, UPnP, NAT traffic, manually setting up routers ????.................... OMG, this is like a foreign language to me
Just to talk you thorugh my install :
1/ Take router out of box, follow instructions on box to install it.
2/ Plug 2 Xboxes and 2 PC's into the router.
3/ Switch on Xboxes and PC's, all connect to the internet/Xbox Live with no issues
4/ Let out big sigh of relief after being given nightmares by posts on PH
Spot on :J:, I was actually surprised when i set mine up, i was expecting hell but it worked with no configuration at all.
NAT sorts everything out, the point about hosting games is a good one, i think UPnP sorts that out in that the 360 asks the router to forward a port to itself.
The only problem i can imagine is that you might not be able to host games on 2 xboxs at the same time. From the top of my head though i think it can use more than one port anyway, so maybe it will work, i haven't tried myself.

I don't like scaremongery (is that a word?) but take a peek at this, then at least you can then decide whether you want to use UPNP or not

I don't know if we have both hosted games at the same to tbh, he does his thing, I do mine. He is not happy lately though as I have been unplugging him so I can make use of the full 30mb for COD4 nights NAT sorts everything out, the point about hosting games is a good one, i think UPnP sorts that out in that the 360 asks the router to forward a port to itself.

No need to be so harsh, no host (randomly chosen player) has an upload speed of 30mb to fill your bandwidth with anyway.Gassing Station | Computers, Gadgets & Stuff | Top of Page | What's New | My Stuff
