All EA series routers filter traffic from '0.0.0.1', breaks system link compatibility for Xbox 360.

There seems to be an issue with the firmware in all EA-series issues where traffic from the invalid IP '0.0.0.1', which is used for system link on all games on both the Original Xbox and Xbox 360 is filtered. LAN game traffic from two consoles on the same network (sent from 0.0.0.1 to 0.0.0.1) can't be sent to each other, while broadcast traffic (sent from 0.0.0.1 to 255.255.255.255) from them can be put on the network, resulting in an issue with being able to see LAN games on the Xbox, but not join them. I've confirmed this issue with at least 3 different people who have EA-series routers. One of them had his linksys router connected to another, and setting his linksys router to bridge mode fixed the issue.

Is there anyway to disable this filtering in the default firmware?

Mind sharing us your network setup and how it was tested so we can look into it further.

It's the same situation with everyone I know who has this issue.

Basically two Xbox consoles (Original, 360, or One[for 360 games]) are connected to the router. When using 'system-link' mode in a game (which is the unique LAN mode for Xbox systems that use the 0.0.0.1 IP instead of one assigned under your subnet), the consoles can't directly communicate with each other, and thus can't play games in LAN mode. The broadcast traffic is sent, which handles match listings, so it's listed in the system link menu, but the consoles can't join a match hosted by the other.

When the two consoles are connected directly, or when one console is connected to the ethernet port of a PC running a LAN tunneling program that's sending system link traffic across a WAN via UDP, the mode works, indicating that the router is filtering the traffic.
