Hello! It seems to me there is a bug in recent DFBSD snapshot.
#ifconfig
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
inet6 fe80::6631:50ff:fe22:18d0%re0 prefixlen 64 scopeid 0x1
inet 10.172.31.120 netmask 0xffffff00 broadcast 10.172.31.255
ether 64:31:50:22:18:d0

10.172.31.120 127.0.0.1 UGHS 0 16 re0
127.0.0.1 127.0.0.1 UH 1 0 lo0
As you can see, system thinks 10.172.31.120 is reachable via re0 not
via lo0, so I can't ping myself.
When I try to ping myself by real IP such messages appear on ttyv0:
