Configuring Access Appliance in IPv4 and IPv6 mixed mode
Access Appliance supports both IPv4 and IPv6 addresses. You can configure the Access Appliance cluster in an IPv4 environment, or an IPV6 environment, or in a mixed mode environment where you have both IPv4 and IPv6 addresses. You can use the Access Appliance services from the client by using IPv4 as well as IPv6 addresses but there are some limitations for specific services. When you configure Access Appliance in mixed mode, you are required to add both IPv4 and IPv6 physical IPs to the NIC(s) of all the cluster nodes.
Note:
If you want to use the Access Appliance service over an IPv4 address, then you must configure the IPv4 address on both Access Appliance and the client. Similarly, if you want to use the Access Appliance service over an IPv6 address, then you must configure the IPv6 address on both Access Appliance and the client. Access Appliance does not convert IPV4 addresses to IPV6 addresses and vice versa for communication.
You can use the below mentioned steps to convert an IPv4 Access Appliance cluster to mixed mode.
To convert an IPv4 Access Appliance cluster to mixed mode
- Install a Access Appliance cluster with IPv4 addresses.
- Connect to the cluster using the master user credentials using the physical or master IP of the cluster.
