Hi guys,

            I am trying to get SAP connection via JCO for a public IP.Here is my jco parameters,

jco.client.gwhost - 111.11.111.111

jco.client.ashost - 111.11.111.111

jco.client.sysnr - 00

jco.client.gwserv - sapgw00

jco.client.client  -800

jco.client.user - xxxxx

jco.client.passwd - yyyyy

I am getting this exception.

Caused by: RfcException:

Hello Chelladurai,

Is there any firewall between the systems?

If the firewall allowing the connection to the SAP Gateway port, from the server where your JCO is running?

Besides the above, the RFC connections on “NATed” environments - ABAP Connectivity - SCN Wiki page might help as well.
