Problem with Billion 7402X and Xbox LIVE NAT

[BaTouSai]

Hi

I have a problem with my Billion 7402X Router.

I have two Xbox 360s on my ADSL.
Gave each xbox a static IP.

Found UPnP on my router and enabled it, it then needed me to specify a port and I used 3074.

Enabled port forwarding but I can't open the same port twice.

I opened the needed ports for the one IP (Xbox 1)

But I can't open the same ports for the second Xbox's IP.

 

[BaTouSai]

Is there any other way to get both Xbox 360s to have an open NAT?

Hi BaTouSai,

Please check if you can change the port number on your second Xbox. If so, then you can add a port forward rule for the other port.

Sorry for the noob question, but where do I change the port number?

The port numbers cannot be changed - thanks Microsoft! Great forward planning.

Here is another way around the problem.
If your ISP allows concurrent connections configure your ADSL modem to allow PPPoE pass-through.
Then on each XBox set up a PPPoE connection.
That way each XBox gets it's own public IP directly on the Internet.
No more NATting or firewalling issues.

Alternatively use a separate ADSL account for each XBox if your ISP only allows a single concurrent connection.

How do I set up my router to allow PPPoE pass-through?

I am with WA and they allow 4 concurrent connections so this should work.

You may find that your router is already configured to allow PPPoE pass-through (PPPoE bridge connections).

RFC 1483 Bridged Connections
Page 40 in the manual : http://www.billion.com/_Internet/usermanual/7402WUM071304154c.pdf

You can also set it up so that your ADSL router still establishes it's own PPPoE connection like you currently have but also allows PPPoE pass-though.
So you'll end up with 3 connections. One for the router which serves your LAN and two for the XBox's.
