saprouter config with RFC on tcp port 33xx

I have a customer who has configured saprouter to allow remote (from the Internet) connections via the SAP GUI. These connections work great. However, when they try to add entries to the route tables for TCP port 3300, 3301, and 3303 the external application they are using (a gateway connection on these ports) fails. Is there some special configuration which needs to take place to allow the RFC connections vs. the regular SAP GUI connections on ports 32xx?

Kind Regards,

Eric J.

I was able to fix the problem by configuring profile parameter "gw/alternative_hostnames" to the public IP of the SAP system.
