I have a legit steam game installed on my PC. Which is having issues with connecting with co-op game mode. So is there any way to exclude those game files or change some options to ensure that Norton firewall is not conflicting with it. Any idea about such option to ensure that Norton firewall is completely allowing that game and has no issues with it. I am not 100% sure that its conflicting but it might be the case. Appreciate your response to this query of mine.
