In o= rder to make this happen, an audit is needed for FreeBSD to check for 240.0.0.0/4 assignment. When assigning a class-e ip to FreeBSD-12, it works except for ICMP. Example, when pinging the FreeBSD machine: ping 240.0.1.199 PING 240.0.1.199 (240.0.1.199) 56(84) bytes of data. ^C --- 240.0.1.199 ping statistics --- 6 packets transmitted, 0 received, 100% packet loss, time 5088ms However, SSH is accessible: nc -v 240.0.1.199 22 Connection to 240.0.1.199 22 port [tcp/ssh] succeeded! SSH-2.0-OpenSSH_7.8 FreeBSD-20180909 This attached patch removes the check for experimental/class-e range address and allows ICMP to work. ping 240.0.1.199 PING 240.0.1.199 (240.0.1.199) 56(84) bytes of data. 64 bytes from 240.0.1.199: icmp_seq=3D1 ttl=3D64 time=3D0.664 ms 64 bytes from 240.0.1.199: icmp_seq=3D2 ttl=3D64 time=3D0.860 ms 64 bytes from 240.0.1.199: icmp_seq=3D3 ttl=3D64 time=3D0.740 ms --=20 You are receiving this mail because: You are the assignee for the bug.=
