Description
Enter a description (name) for the interface here.
IP configuration
Bridge with
IP address /
IPv6 mode
Choosing 6to4 on an optional interface will make it use the next available /64 prefix within the WAN interface's 6to4 prefix (which is determined by its current IPv4 address).
IPv6 address /
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.
> Managed address configuration
If this option is checked, other hosts on this interface will use DHCPv6 for address allocation and non address allocation configuration.
> Other stateful configuration
If this option is checked, other hosts on this interface will use DHCPv6 for non address allocation configuration, such as DNS.
 
  Note:
be sure to add firewall rules to permit traffic through the interface. Firewall rules for an interface in bridged mode have no effect on packets to hosts other than m0n0wall itself, unless "Enable filtering bridge" is checked on the System: Advanced functions page.
Optional has been disabled because there is no OPT interface.
