Hi guys, my vpn server is being attacked by a /24 subnet, not just a single ip. i created a filter rule which is input, and source address is the whole subnet 92.63.194.0/24 and the action is dropped. Few hours later the same person still tries to connect with failed attempts, so i changed the action to reject with network unreachable message. He can still access the server. i would really appreciate if you can help me with blocking them!
