EDIT: Solved this retarded problem by clicking a link to 192.168.1.100/Gateway Mode. I'm going to see if simply leaving the EPC2425 in bridge mode as a modem will fix the two xboxs closed NAT problem. If not I'll get a router and attach it.
Just going some research here, i don't think you're going to be able to have multiple xboxes online at any one time due to a limitation with NAT. YOu will probably find you will require multiple public IP addresses which home broadband providers don't genreally give.
the two xboxes will be published on the internet with one IP address, when data comes from the internet to your broadband modem/router it will generally ship all that traffic to the first xbox that connected over upnp or if you have a static dmz host it will send all traffic to that.
there may be a possibility to change the cisco to bridge mode and add in another router that is xbox live compatible
here is a guide that may help: http://www.techknowlogy.jigsy.com/
i thinkt however though that the limitation will lie with UPC and the cisco modem, you may find a workround with static DHCP, Portforwarding & Port triggers but im not overly sure.
