IP address /
IPv6 mode
Choosing 6to4 on the LAN interface will make it use the first available /64 prefix within the WAN interface's 6to4 prefix (which is determined by its current IPv4 address).
IPv6 address /
Using a number less than /64 will cause RAs not to be announced as there aren't enough subnet bits. i.e. /48
IPv6 Prefix Delegation /
Select site-level aggregator ID and ISP prefix length (decimal notation).
If ID is 10 and the client is delegated an IPv6 prefix 2001:db8:ffff and prefix 64, this will result in a single IPv6 prefix, 2001:db8:ffff:A::/64 .
IPv6 RA > Send IPv6 router advertisements
If this option is checked, other hosts on this interface will be able to automatically configure their IPv6 address based on prefix and gateway information that the firewall provides to them. This option should normally be enabled.
Flags
If Managed is selected, other hosts on this interface will use DHCPv6 for BOTH address and non address allocation configuration.
If Other is selected, other hosts on this interface will use DHCPv6 for non address allocation only, like DNS.
MTU bytes
Enter the MTU you want advertised here.
 
  Warning:
after you click "Save", you must reboot your firewall for changes to take effect. You may also have to do one or more of the following steps before you can access your firewall again:
  • change the IP address of your computer
  • renew its DHCP lease
  • access the webGUI with the new IP address
