Hello, in the last few days the border router has been showing me an alert that the connection tracking table is full. Could this cause the router to experience packet loss? This is because for the past few days this packet loss problem has been occurring even with directly connected routers that work with static routes. Since it is a border router that does not use NAT or packet or connection marking, could tracking be disabled?

Since it is a border router that does not use NAT or packet or connection marking, could tracking be disabled?

AFAIK if firewall filter config is empty, then connection tracking is omitted. Raw firewall rules don't affect it, they don't rely on connection state.
