Hi,

Please read:-
forums.xbox.com/.../811997.aspx

And post back your details in full (the bits that are in bold on that post) so that people may help

If you are wireless can you also state whether you are using the white or black external adapter or the Xbox 360S Internal adapter

Thanks

Your "modem" appears to be a gateway (modem+router), which if so creates a problematic double NAT situation. To verify double NAT is the issue, please log in to the web interface of your Netgear router and note the WAN/Internet IP it reports (WAN IP, not
the LAN IP!). If that IP differs from the one reported by
http://www.tracemyip.org, then your Xbox is behind multiple layers of NAT (double NAT) and getting open NAT will require special steps.

Based on some information I am finding online, your Visionnet DSL "modem" may actually be a gateway (modem+router), which if so creates a problematic double NAT situation. To verify double NAT is the issue, please log in to the web interface of your Cisco
router and note the WAN/Internet IP it reports (WAN IP, not the LAN IP!). If that IP differs from the one reported by
http://www.tracemyip.org, then your Xbox is behind multiple layers of NAT (double NAT) and getting open NAT will require special steps. (And any reports by either Xbox that it has/had open NAT were false,
which does sometimes happen in a double NAT situation--the One seems more accurate than the 360.)
