This is going to be a bit of longshot, but here it goes.
A friend of mine is playing an MMORPG, and it has been proven that the game benefits quite a lot from changing the MTU size to 576. However, this adversely affetcts most other activities on the internet, as you would have guessed.
Seeing how most mobos nowdays ship with more than a single NIC, someone posted a quick guide to dedicate one of them to play the game with a lower MTU size, while maintaining the other one for general use intact. The only thing he is suggesting there is manually changing the metric to a lower value, then executing the following in command prompt to add a persistent route:
route -p ADD <game's server address> MASK <subnet mask> <router's local address> IF <device ID> METRIC <lowered metric>
If done correctly, this should route all the traffic going from and to the server to the specified NIC in the command string. Apparantly many others have been successful at this, except this guy is only able to send packets through the dedicated card, and receive through the general one.
What could have possibly caused this anomaly? Where would be a good place to start diagnosing it?
