I have the Xbox connected via wired. The router just doesn't seem to want to give out an IP. DSL /w router PPPoE. I have DHCP enabled, it works fine for my desktop computer and for my laptop via wireless. UPnP is also enabled and works fine on the computers. Nowhere in the DD-WRT control panel can I see any status signal of the Xbox connection, so it's not giving out the IP (right?) Well I'm not sure, and I don't know what other settings to check. I did try with the router firewall disabled, still the same thing. I have also tried manual settings on the Xbox like these: (These are the settings according to the Status -> Router tab in DD-WRT for WAN) IP 192.168.1.102 (100-101 is desktop and laptop) Subnet Mask 255.255.255.255 Gateway 188.8.131.52 DNS 184.108.40.206 DNS2 2220.127.116.11 Tried "Automatic" settings on Xbox as well. Would not work. I have also tried switching the Xbox to LAN settings: Subnet Mask 255.255.255.255/255.255.255.0 Gateway 192.168.1.1 DNS 192.168.1.1 DNS2 192.168.1.1/0.0.0.0 Same results, no go. I have tried plugging wire directly to DSL modem and it works fine, so I don't think the wire is the problem. It never gives out the IP. NAT is "open", UPnP enabled, DMZ enabled for the Xbox IP, router firewall on/off, etc. It's baffling me why it won't work and I'm beginning to think there might be some sort of bugs in DD-WRT v23 SP2 that is preventing me from getting this to work.
