SAP Logon error: Connect from SAP gateway to RFC server failed
When you try to login to SAP through Winshuttle software, you get an SAP Logon error message about the partner *IP address* not being reached.
This issue can be caused by a firewall between the client and gateway that converts external IP addresses into internal addresses.
The gateway host and the actual target are usually identical. In this case, you can use parameter gw/alternative_hostnames to indicate to the gateway than the external IP address received identifies the host.
Please see the attached SAP note: 148832.
