I need to block communication with one IP address (especially SMB). But simply blocking all communication with this particular IP will suffice. I have created the rule prohibiting all UDP and TCP communication with this IP, but the rule has no effect. PC, which I need an access to be restricted to, is still completely accessible from that remote IP. Strangely, ICMP blocking, which I used for testing, works correctly. Any advice is appreciated.
