.NET Connector Login Problem

I want to generate a SAP Proxy by using the SAP Connector. When starting the wizard, i can use the login information of a account from the SAP GUI.

By doing so, i always get a connection time out, and i am not able to connect to the SAP via the wizard (in SAP GUI it works fine..)

Whats it with the port 3300 ? where does the router string go in the wizard login screen ?

I played around with the router string and i got a 'route permission denied' exception. ( port 3300 was used, but i didn't specified it !!)

any help on this ?

    The .NET Connector uses RFC to connect to the target SAP system. While SAPGUI uses the TCP port 32xx, the undelying RFC always uses the TCP port 33xx, where xx is the system number of your target SAP system.

    The fact that the SAPGUI works but RFC does not inidicates that the TCP port 3300 is not opened on the SAP Router. Please ask your system admin to open the port 3300 on the SAP Router. For deatails, please refer to the SAP Router doc.
