Actually, there are two issues: 1) dhcpd is listening on random port (UDP) for all interfaces, no configuration option or CLI switch can fix with this situation. 2) moreover, dhcpd is listening for UDPv6 too, even if you include -4 option for dhcpd: $ cat /etc/default/isc-dhcp-server | sed '/^$/d;/^#/d' INTERFACES="br0" OPTIONS="-4" $ ps w 15686 PID TTY STAT TIME COMMAND 15686 ?
