Title: Block private networks - blocks 100.75.* network
Post by: ryp43 on December 09, 2022, 10:44:14 AM

Hi!

My OPNsense is blocking connections from address 100.75.* with labeling "block private networks from WAN" while "Block private networks" is checked under the WAN interface.

though help for this option states: "When set, this option blocks traffic from IP addresses that are reserved for private networks as per RFC 1918 (10/8, 172.16/12, 192.168/16) as well as loopback addresses (127/8) and Carrier-grade NAT addresses (100.64/10). This option should only be set for WAN interfaces that use the public IP address space."

I will appreciate any help.

Thanks in advance

100.75.* is part of 100.64/10.

100.64/10 is 100.64.0.0 - 100.127.255.255
