Quote from: meyergru on November 13, 2025, 11:28:42 AMFor OpnSense, you define the WAN interface IP with a netmask of /32 and set the "IPv4 gateway rules" to your gateway, in which you check both "Upstream Gateway" and "Far Gateway" and select the WAN interface and gateway IP.

Quote from: meyergru on September 23, 2025, 02:26:28 PMIf you see traffic that is not destined to your IPv4, it might be so-called "unknown unicasts". Their forwarding is a normal function of an L2 switch.
Quote from: meyergru on September 23, 2025, 02:26:28 PMIt will not help if you configure your interface as /32 and set up a pointopoint route to your gateway ip - although that could/should also be done regardless (I do that). Otherwise, you might not get traffic to your "subnet neighbors".
Quote from: meyergru on September 23, 2025, 02:26:28 PMIf you want to block such traffic before it even hits your OpnSense, you can use Hetzner's Robot Firewall to filter against your own IPv4 (I do that, too, and it works).
