Virtual IP Is Used for Outbound Connection Instead of Real IP in WLS 12.1.2
Last updated on FEBRUARY 11, 2017
Applies to:Oracle WebLogic Server - Version 22.214.171.124.0 to 126.96.36.199.0 [Release 12c]
Information in this document applies to any platform.
When the system is configured with a virtual interface and the virtual IP is configured in the listen-address WebLogic 12.1.2 uses this virtual IP instead of the real IP.
The behavior is different in previous releases: in previous releases, although the listen address was configured with the Virtual IP, the IP used for the outbound connection was the real IP address.
- Set an interface and virtual interface
You can observe that the IP used as the source IP in the case of WLS 12.1.2 is the virtual IP (in this example 10.163.245.107) while the source IP in the case of WLS 10.3.6 is the real IP (in the example 10.163.245.106).
It can cause connectivity problems when the Virtual IP doesn't have internet access.
