6in4 Tunnel
The 6in4 tunnel mode utilizes explicit IPv4 tunnel endpoints and encapsulates IPv6 packets using 41 as the specified protocol type in the IP header. A 6in4 tunnel broker
provides a static IPv4 server endpoint, decapsulates packets, and provides routing for both egress and ingress IPv6 packets. Most tunnel brokers provide a facility to request
delegated networks for use through the tunnel.
Tunnel Server IP – Input the tunnel server IP address provided by your tunnel service.
Local IPv6 Address – Input the local IPv6 address provided by your tunnel service.
Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if the default global DNS setting on the Network
Settings → DNS page is "Automatic".
Additional IPv6 DNS Server – Secondary DNS server.
Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this may be required. Prefixes specified here only
take effect if those supplied by the connection are insufficient to configure your LANs.
Delegated IPv6 Network – Additional network available for delegation to LANs.
Example Configuration:
6rd Tunnel
IPv6 Rapid Deployment (6rd) is a method of IPv6 site configuration derived from 6to4. It is different from 6to4 in that the ISP provides explicit 6rd infrastructure that handles
the IPv4 ↔ IPv6 translation within the ISP network. 6rd is considered more reliable than 6to4 as the ISP explicitly maintains infrastructure to support tunneled IPv6 traffic over
their IPv4 network.
6rd Prefix – The 6rd prefix and prefix length should be supplied by your ISP.
IPv4 Border Router Address – This address should be supplied by your ISP.
IPv4 Common Prefix Mask – Input the number of common prefix bits that you can mask off of the WAN's IPv4 address.
Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if the default global DNS setting on the Network
Settings → DNS page is "Automatic".
Additional IPv6 DNS Server – Secondary DNS server.
Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this may be required. Prefixes specified here only
take effect if those supplied by the connection are insufficient to configure your LANs.
Delegated IPv6 Network – Additional network available for delegation to LANs.
