Abstract
The Oracle WebLogic Server configuration wizard permits configuring a listening address as well as SSL and non-SSL port numbers for each server instance in a domain. Even when administrators do not specify listen addresses, WebLogic Server instances will by default accept incoming requests through all configured network interfaces in the host where they reside, including the loopback interface and using the localhost string.

Notes
- 1.
Reaching a WebLogic Server instance from outside the host where it is running also depends on whether or not traffic destined to the network address specified in the configuration is permitted.
- 2.
Custom network channels inherit values from the default network channel for properties that are left undefined.
- 3.
Be aware that when multiple network channels are created on a single network interface, there will be some overhead due to context switching.
- 4.
The external listen address and port number must be specified for scenarios such as when running asynchronous web services that expect a callback.
- 5.
Replication channels for clusters are not configured with SSL protection by default.
- 6.
Enabling the administration port requires a full domain restart to become active.
- 7.
This may also be configured using WLST by editing the properties of the UnixMachineMBean, using methods setPostBindUIDEnabled and setPostBindGIDEnabled.
