find /usr -name ipguard
pkg install ipguard
/usr/local/sbin/ipguard -xz -u 300 bge0
or
PATH=$PATH:/usr/local/sbin; export PATH
ipguard -xz -u 300 bge0
Remove it. There's a proper rc(8) script in /usr/local/etc/rc.d/ipguard.I tried to start ipguard at boot time on /etc/rc.local with content
# Add the following lines to /etc/rc.conf to enable ipguard:
#
# ipguard_enable="YES"
# ipguard_interface="iface"
# ipguard_flags="-u 300 -xz"
