Hello LinksysInfo forums, For the past week I've been digging around online on how to run two Xboxes on the same network without any NAT issues. After asking /r/techsupport on reddit I was led to this tutorial which not only explains the problem, it gives a solution: http://jakebillo.com/two-xboxes-one-router-making-upnp-work-using-dd-wrt-or-tomato/ Apparently I need "Static DHCP" to be able to do this. Both Tomato and dd-rwt are viable options in this tutorial. After going to polarcloud.com I discovered my router (a Linksys E1000) was too new to support Tomato. That's when I found Tomato USB which supported the Linksys E1000, but hasn't been updated since 2010. The Tomato USB website links here to this thread: http://www.linksysinfo.org/index.php?threads/tomato-modifications.26037/ with a list of Tomato mods. So I'm left with deciding which Tomato mod to choose and yet I have no clue. All I need from it is to be reliable and have Static DHCP. Any insight would be beneficial to my situation, Thanks!
