TomatoUSB

Hey Tomato Community,

Long time listener, first time poster.

I have recently upgraded from an old router to a… less old Linksys E1000. I have the newest version of Tomato USB installed on her as well.

I have tried anything, every bloody site can throw at me, but for the love of the flying spaghetti monster I can NOT get an open NAT on both consoles at the same time.

I have trigger the proper ports, enabled and disable UPnP, set the MTU 1364 and any other thing I can find on these here interwebs.

I'm about ready to pull my hair out. Any help would be fantastic.

You can't if you have one public IP, one port, going to two internal machines at the same time. How does your router distinguish traffic between both?

There's a lot of mis-information about this on the net, even the definition of what Microsoft mean by "open-nat" is unclear.

BUT some folk claim it works with miniupnpd (which is what is used in tomatousb).

You must not use static ips on the xboxes (static reserved via router fine), since apparently Microsoft don't enable upnp unless they also use dhcp (no doubt a clause in an obscure spec somewhere).

The only way I can imagine it does then work is that the xboxes understand each other exist via upnp communication with the router and agree to use different ports or somehow timeshare the key ones!

Maybe it never really works, just at the moment you test the connection upnp sets the port forward?

You can't have open NAT on both Xbox as you cannot port forward one port to two IP's on the same network. But you can try this:

1) Assign static IP's to XBOX 1 and XBOX 2
2) Assign XBOX 1 to the DMZ
3) Port forward 3074 (UDP and TCP) and 1863 (UDP and TCP) to XBOX 2

This will not give you an open NAT but should help with connection issues

Well, good news and bad news then, I guess.

I really appreciate all the info you guys took the time to post. I guess i'll play around with a few of the thoughts here and see what gets me the most stable and usable results.

Thanks again,
Miltor

It can be done. I used to have 2 xboxes with open NAT using a WHR-HP-G54 running DD-WRT with minupnpd.
