Configure custom network channels

Before you begin

The server instance for which you configure a custom network channel does not need to be running.

A network channel is a configurable resource that defines the attributes of a network connection to WebLogic Server. For instance, a network channel can define:

The protocol the connection supports.
The listen address.
The listen ports for secure and non-secure communication.
Connection properties such as the login timeout value and maximum message sizes.
Whether or not the connection supports tunneling.
Whether the connection can be used to communicate with other WebLogic Server instances in the domain, or used only for communication with clients.

For more information on network channels, see Configuring Network Resources.

To configure a custom network channel from the Administration Console:

If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the left pane of the Console, expand Environment and select Servers.
Select the server whose network channels you want to configure.
Select Protocols > Channels.
Do either of the following:
- Click the name of an existing channel and edit the configuration, as desired. Click Save when you have finished.
- Create a new channel, as described in the rest of this topic.
Click New.
Enter the name of the new network channel and the protocol it will use, then click Next.
Enter the following information:
- Listen address
- Listen port
- External listen address
- External listen port
The external listen address and port are used to support Network Address Translation (NAT) firewalls. These should match the IP address or DNS name that clients use to access application on the server.
Click Next.
Configure any additional properties for this network channel.
For more information, see Configuring a Channel.
Click Finish.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
Not all changes take effect immediately—some require a restart (see Use the Change Center).
