Understanding Requirements for Communication Between vGW Series IPv6 Components and Juniper Networks IPv4 Servers
When a vGW Series component with an IPv6 address must communicate with a Juniper Networks server that is on an IPv4 network, an incompatibility exists. To overcome the IP protocol incompatibility, the following capabilities and implementations must exist:
- Connectivity to the IPv4 Internet.
- An address translation mechanism such as NAT64.
- A DNS solution such as DNS64 that provides an authentication, authorization, accounting, and address (AAAA) record with an IPv6 address through which the server can be reached.
The Juniper Networks servers that vGW Series communicates with that could be affected by this compatibility issue are:
- updates.altornetworks.com—Update server.
- anubis.altornetworks.com—Log collection upload server.
- update.juniper-updates.net—vGW AntiVirus signature updates server. This server is accessed only by the vGW Security Design VM.
