Players of Call of Duty Black Ops 2 on PlayStation are encountering persistent multiplayer connectivity problems due to NAT type conflicts. The game’s peer-to-peer system requires UDP port 3074, but when two consoles share the same home router, port conflicts force one player into a "strict" NAT type, preventing them from joining friends. Despite extensive troubleshooting, the issue remains unresolved. Attempts to secure refunds have been denied by PlayStation, which states the developer is actively working on a fix. This ongoing problem affects players seeking smooth multiplayer sessions and highlights challenges in legacy network architectures.
- Issue stems from UDP port 3074 conflicts on shared residential routers.
- PlayStation denies refunds while developer works on a solution.
