Information in this document applies to any platform.
Using Oracle API Gateway version OAG_18.104.22.168.0_SP3 as an SFTP security layer, there was a need to use the default TCP port for SFTP (port 22).
The system uses SSHD for remote management of the operating system, which also uses the default port for SSH (22).
In order for these to coexist, the SSHD has been reconfigured to listen explicitly on a unique interface.
The corresponding configuration is then required for the SFTP service, to listen only on a different interface.
When using Policy Studio to implement this configuration, an error "You must enter a binding address. Use * to bind to all available network interfaces." is returned.
The same method is used to specify the Bind address for some HTTPS services without issue, so the assumption is that the value or format of the IP address has been correctly specified.
An attempt was made to use the default '*' value for the Binding address and change the port value. This works as expected. The port value works for those both above and below the system default ports number (> 1024) which indicates the issue is not permission related.
Trying any value in the Binding address field (other than '*') produces an error condition.
