TomatoUSB

When running a connection test with a PS3, the result comes up with something like:

"Your router may not support IP-fragments and communication features of some games may be restricted."

If you disable QOS, the problem goes away and the connection test reports back complete. Some users have had this issue off and on through the various tomato versions. It SEEMS related to QoS.

Anyone experience anything similar?

What Tomato version(s) have you personally tested and confirmed to have this problem?

What if you keep QoS enabled, but only turn off the inbound QoS?
You can do this by setting all inbound limits for all classes to "None".

I will test your suggestion and report back in a short while…

So far I have tried changing "reduce packet size," and "prevent DNS rebind attacks" settings, but it occurs either way. I have seen this bug PERSONALLY on ver49 vpn, and 48ext.

Thanks, Teddy!

Hey, Teddy!

Based on your suggestion, I examined my QoS settings. My game consoles have a class of their own. My QoS rules place all other traffic in other classes. So, instead of turning off the inbound QOS for ALL classes, I simply turned it off for the class that the game consoles are in and voila! The problem disappeared!

The setting was at 80% for the console class, when I changed it to none, once again, the problem was gone. I left all the other classes as they were.

Does that shed any light on the situation?

Thanks!

I have a somewhat similar issue. I downloaded the Slingplayer client from Slingbox.com and installed it. I got everything set up and it all loads up. But when I try to connect to any of my slingplayers it won't. I get an error.

If I disable QoS, it connects fine. If I enable it again, it won't connect.

I've tried setting up port forwarding as suggested on the Slingplayer site but it's not an inbound connection issue. My request is being sent out to establish the connection so the forwarding should really be the issue.

Also if I drop my computers IP in the DMZ it connects as well.

Any suggestions? Or any additional info you need?

I'm running 2.4 Lite ND on a WL-520GU.

SeaburyNorton,
Do you actually have any problems when using your PS3 with QoS enabled, besides the failing connection test?

Jimbo,
Your SlingPlayer issue may or may not be the same… Have you tried to activate UPnP on the router? Have you tried to do what SeaburyNorton did, and disable inbound QoS for one class only, the one your SlingPlayer falls into? Or just disable all inbound QoS (if you can't setup a class for the player), but keep outbound enabled?

If it doesn't help, please provide your detailed port forwarding settings (basic and triggered) and qos settings, enable logging of connections blocked by firewall, and provide the system log during the time slingplayer is trying to connect.

To be honest, I didn't have the problem long enough to say. I had recently re-done the qos settings and that's when the problem came up. I do know that the issue would primarily be the voice communications through headsets.

Well, what inbound QoS does is dropping packets when the number of arriving packets exceeds the bandwidth limit set by QoS rule.

I suspect that the connection test is trying to transfer the data at a high speed, and when it sees lost packets (caused by QoS kicking off), it complains that "communication features of some games may be restricted". In reality, it may not be a problem during the game - IF allowed bandwidth is enough for voice communications.

However, it's always a good idea to not restrict the inbound bandwidth for the classes you want to have the highest priority.

You can find a lot of discussions on linksysinfo forums about the usefulness of inbound QoS and whether or not it makes sense to utilize it at all - because you can't control how fast packets are arriving to your network from the WAN, the only thing your router can do is to drop packets if they are coming in too fast, effectively slowing the TCP traffic down (but not UDP though).

Personally, I only restrict the inbound bandwidth for the lowest priority class (P2P traffic).

Teddy,

I suspect you are 100% correct in your assessment. The very last phase of the ps3 connection test does an upload/download speed test. :)
