Objective

The Internet Protocol (IP) is responsible for delivery of traffic across a network. The CVR100W uses both IPv4 and IPv6 IP modes. These protocols do not require the two end points to confirm connection through a "hand shake" security procedure, which makes them quick and efficient. They also use the best effort delivery methods to direct the packets. This article explains how to configure the IP mode on the CVR100W VPN Router.

Applicable Device

• CVR100W

Software Version

• 1.0.1.19

IP Mode

Step 1. Log in to the web configuration utility and choose Networking > IP Mode. The IP Mode page opens:

Step 2. From the IP Mode drop-down list, choose one of the following:

Note: IPv4 is the older, but most common, protocol version used that gives an address to each device connected to the Internet. However, these addresses will eventually run out, so IPv6 was created to succeed the IPv4 and will eventually upgrade the Internet Protocol all together. These two protocols are very similar and can be used for any IP mode specifications below.

• LAN:IPv4, WAN:IPv4 — The LAN and WAN ports both use IPv4.

• LAN:IPv6, WAN:IPv4 — The LAN port uses IPv6 and the WAN port uses IPv4.

• LAN:IPv6, WAN:IPv6 — The LAN and WAN ports both use IPv6.

• LAN:IPv4+IPv6, WAN:IPv4 — The LAN port uses both IPv4 and IPv6 and the WAN port uses IPv4. Both IP modes on one port will work together simultaneously, but packet traffic will still only use one protocol.

• LAN:IPv4+IPv6, WAN:IPv4+IPv6 — The LAN and WAN ports both use IPv4 and IPv6. Both IP modes on one port will work together simultaneously, but packet traffic will still only use one protocol.

Step 3. (Optional) For all modes, besides the LAN:IPv4, WAN:IPv4 IP mode, the Show Static 6to4 DNS Entry drop-down arrow becomes available. 6to4 is a tunneling feature that allows the user to send IPv6 packets from an IPv6 LAN over an IPv4 WAN network. Click the Show Static 6to4 DNS Entry drop-down arrow. The Static 6to4 DNS Entry fields appear:

Step 4. Enter no more than 5 domain-to-IP mappings in the Domain and IP fields. 6to4 mapping is when a domain name is mapped to an IPv6 address.

Step 5. Click Save.

Step 6. The Information window appears.

Step 7. Click OK.

Caution: The device will be assigned a new default IP address in order to change the IP mode.
