The firewall is not recognizing your outbound rules.
The firewall is not recognizing your outbound rules.
After much effort trying to understand why Rainbow Six Siege and Modern Warfare beta wouldn't start, I realized certain ports weren’t working. In my case, UDP 3074 for Call of Duty was open on my router but blocked by Windows Firewall. I managed to fix it by adding an inbound rule that allowed the connection. The challenge now is figuring out why the rules stay closed despite being added. I usually delete them, restart the PC, and try again—sometimes it works about half the time. If not, I repeat the process until it functions. My main concern is that the firewall is still preventing access to the online services needed for the games. Even after adding the right rules, they don’t stay open. Why do I have to repeatedly delete and re-add them? Thanks, Kev.
Because you should focus on outbound rules first. Before any packet is sent by any server, you must request that packet by sending your packet - then and only then server answers. Is possible that you get some packets only because you start your game and gameserver sends you some data usinf opened inbound ports, but then your game is unable to respond and you loose that communication. Anyway, you may try disable windows firewall and install comodo free firewall, set it to custom mode with some paranoid settings and check how it really works. Strange for me is that your method works, even sometimes.
Thank you for your message. I've updated the outbound rules and encountered the same problems. Regarding your questions, Avast and Malwarebytes are common choices, but other options may suit your needs better. Comodo is also a viable alternative. Let me know if you'd like more details!
Comodo isn't a substitute. It's a firewall, Avast is an antivirus. Surely a firewall can catch some malicious activity—most viruses trying to reach the internet—but it's not meant for that kind of defense. YET... modern firewalls like Comodo offer many features aimed at safety against viruses (even with AV modules). Comodo merely highlights connection alerts; you can then identify issues.
