Not able to connect to SAP over extranet

[Former Member]

Hello,

Our customer's SAP server has an intranet IP address and an extranet IP address. To use the intranet IP address, I just VPN into the customer's site.

After I VPN into the customer's system, I am able to connect to the server, from the SAP GUI as well as from my java code.

I prefer using the extranet IP address. I am able to use the SAP GUI to connect to the system over the extranet. However, when I use the extranet IP address within my code, I get a "connection timed out" error message.

I am wondering if someone can enlighten me on what could be going on? I would imagine the SAP GUI is internally using the same RFC as my code does to connect to the system. Then why does my code fail?

Thank you in advance for your help.

Hello Sunny,

you can use Ethereal to sniff the Ports the Java client is using when he connects sucessfull to the Server. There must be a different Firewall setting to the Extranet IP.
