So before I type out this long post, I just want to introduce my post in one sentence: I have tried different routers, and different tomato builds (and custom builds as well), and different systems. So here we go! My gaming problem here is specifically with my PS3 and 360. When I setup my wifi and my router, I goto Internet Connection Test. When I do the test I get the following: Obtain IP Address: Succeeded Internet Connection: Succeeded Playstation Network: Succeeded UPnP: Succeeded NAT TYPE: Type 2 Connection Speed (Download): - (never does this for some weird reason,though it works when i use DDWRT) Connection Speed (Upload): - (never does this for some weird reason,though it works when i use DDWRT) and on the bottom of the screen it says: "Your router may not support IP-fragments and communication features of some games may be restricted" Now im a HEAVY modern Warfare 2 player, in the game it says i have a STRICT NAT, so i have a hard time connecting to other players. on ps3, it says i have a strict nat on 360, it says OPEN on pc it says OPEN i have tried putting my ps3 in a DMZ, as well as forwarding the ports manually. The question is, how do i fix the "Your router may not support IP-fragments and communication features of some games may be restricted" error. This is what i have tried: (on both routers and ps3's) 2 different routers (Asus WL-520GU and Buffalo WHR-G54S) Official Tomato Firmware (v 1.25, v 1.26, v 1.27) on both routers Other (unofficial) Tomato mods (hardc0re,Teddy Bear, and Victek) a different PS3 Putting my ps3 in a DMZ Enabling UPnP Manually forwarding the ports needed for Modern Warfare 2 and the ps3 Temporarily disabling all the firewall features of the router Changing the MTU if anyone could please help me, that would save me months of testing/configuring. the only thing i have tried that worked (on both routers, and ps3's) was DDWRT i dont really like DDWRT, and would rather have tomato, especially with my Asus WL-520GU router (tomato works great with the teddy bear mod) if there is any more information needed to help me out, i sure wont mind getting the info! Thanks!
