Multiple cod mw games wont connect trough openwrt

Installing and Using OpenWrt
1

My activision/blizzard games working but cod mw I and cod mw III wont connect to the internet. Many other games working but not this games. Tried to ping activision blizzard domains, ang ping working. Im using adblock and banip but when i disabled and rebooted router and flushed dns in windows 11 games still wont connect. I also got vlans fpr separating subnets. But many of my games working but not cod mw. Cod mw I is on battlenet, and cod mw III is on steam. Problem started when i switched from opnsense to openwrt. Im using it on x86.Everything working but not cod games.

Please help me solve this issue.

P.S.: Im using openwrt 24.10.2

EDIT: Restored default configuration with no banip and with no adblock. Now everything works fine. Disabling banip and adblock and rebooting router must left something.

So, we need to see your banip and adblock configs.

Decided to not use any blocklists. There was only ads/malicious/malware/phishing/scam/attackers blocklists. There was nothing related to gaming. And everything worked but not multiple call of duty games. Other activision-blizzard games, and many other games just worked. Without any blocklists call of duty workng properly.

Some of blocklists are paranoid blocking sites with google or facebook federated login button.
