tested on ZyWALL 110 with V4.33(AAAA.0)ITS-WK19-r88384

This is the config for OPT without unicast or Metric

interface opt

upstream 1048576

downstream 1048576

mtu 1500

type external

ping-check 194.168.4.100 method icmp period 5 timeout 5 fail-tolerance 5

igmp version 2

no ping-check activate

use-defined-mac

mac 00:24:1D:xx:xx:xx

ipv6 enable

ipv6 dhcp6 client

ip proxy-arp 192.168.254.0/24

ipv6 nd ra accept

ip address dhcp


This is the config for OPT with unicast without Metric (after inactivate and activate of OPT)

configure terminal

interface opt

ip address dhcp unicast


interface opt

upstream 1048576

downstream 1048576

mtu 1500

type external

ping-check 194.168.4.100 method icmp period 5 timeout 5 fail-tolerance 5

igmp version 2

no ping-check activate

use-defined-mac

mac 00:24:1D:xx:xx:xx

ipv6 enable

ipv6 dhcp6 client

ip proxy-arp 192.168.254.0/24

ipv6 nd ra accept

ip address dhcp unicast


This is the config for OPT with unicast and then Metric set to 2

interface opt

upstream 1048576

downstream 1048576

mtu 1500

type external

ping-check 194.168.4.100 method icmp period 5 timeout 5 fail-tolerance 5

igmp version 2

no ping-check activate

use-defined-mac

mac 00:24:1D:xx:xx:xx

ipv6 enable

ipv6 dhcp6 client

ip proxy-arp 192.168.254.0/24

ipv6 nd ra accept

ip address dhcp metric 2
