To configure an IPv6 VNE provider, you must meet the following requirements:

You must complete the following configurations:
1. An IPv6 WAN interface with a public IPv6 address. See Configure physical interfaces.
2. An IPv6 DNS server. See Configure DNS servers.
3. An IP tunnel depending on your VNE provider. For example, Cross Pass (XPass) uses an IPv4-over-IPv6 (4in6) IP tunnel. See Add an IP tunnel.
4. The necessary routes to your VNE provider's gateway. See Add a unicast route.
You must obtain the following details from your VNE provider:
- The FQDN provided by your DDNS provider
- DDNS server URL
- DDNS ID
- DDNS password
- Username
- Password

Configure dynamic DNS

Configure an IPv4 DDNS provider or an IPv6 VNE provider as follows:

Go to Network > Dynamic DNS and click Add.
Enter the hostname you received when you registered with your DDNS service provider using the following format:
```
<accountname>.<DDNS provider>.com
```
Some providers may use a different format. For example, you may need to specify the domain and subdomains for some providers and use just the domain as a sign-in name. Check with your DDNS provider.
