Hi, I know that they were several threads about this, but they are so far away in the forum now that I think its better to start a new one in hoping to helo solve the issue. Today I installed a new router and with my previous one I never had any connection problem with Crysis 2. With my new one I was getting kicked right in the middle of a game and it was showing me this message : Your connection to your host has been lost. The only way that I could fixed this problem was enabling DMZ on my router for my computer. I saw that people that were sharing my problem have a D-Link has a routeur just like my new one. My new router is a DIR-665 and I hope that Crytek will be able to contact D-Link to try to fix this issue, because I dont really like enabling DMZ. I only do it when I go play Crysis 2 and then I turn it off. Hope these informations will help to fix this problem.

In the link below, this is me checking my crysis 2 log files on how many times I've been disconnected. I also show that I let Crysis 2 through my firewall and is port forwarded through my router.

In this link below, I show a sample video of me getting auto disconnected during a game

NOTE that This only happens in Crysis and Crysis 2. This problem does not happen in any other pc games that I own
