# Using SUM with IPv6 networks

You can deploy to remote nodes in IPv6-based networks for Windows and Linux node servers.

For Windows-based servers to communicate with remote node servers, SUM uses either existing credentials or the user-provided user name and password to connect to the admin$ share. This share is an automatic share provided by Windows Server. After SUM connects to the admin$ share, it copies a version of the engine to the node server for the duration of the installation. After this engine starts, SUM uses this engine to communicate between the local and remote node server.

Open the firewall ports SUM needs for communication. After the installation is completed or canceled, SUM stops the remote engine, removes it from the node, closes the port on the Windows firewall, and then releases the share between the node and the local system.

For Linux-based servers to communicate to remote node servers, SUM starts by using the user-provided user name and password to create an SSH connection to the node server. After it connects, SUM copies the engine to the node server for the duration of the installation. After this engine starts, SUM uses this engine to communicate between the local and remote node server.

During this process, SUM opens ports in the iptables firewall to enable SUM to communicate with the SUM engine over SSL to pass data between the local and remote systems. When the installation is completed or canceled, SUM stops the remote engine, removes it from the target server, closes the port in the iptables firewall, and then closes the SSH connection to the node server.

To set up IPv6 networking, refer the documentation for your operating system.
