SNC enabled RFC not working. please help

[Former Member]

I have set up a READ RFC from Solman(on NON DMZ) to managed system(on DMZ zone) named SM_<SID>CLNT<client>_READ with SNC enabled.

When I click on SNC as "active" in Satus of SNC protocol in Logon & Security area. It is throwing the below error when I do connection test.

Logon	Connection Error

Hello Anand/Divyanshu,

I have followed the links mentioned by you but no luck. I checked the settings of my system as per the links mentioned by you, but no luck.

Raised a request to open port no 48XX from Initiator system host to acceptor system host. Once this port will be opened, I shall again check the RFC and update you the result.

Hello Anand/Divyanshu,

I have followed the links which you have mentioned and checked all the settings in my system and found everything is OK. Only 1 thing I found that in link http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/4e515a43-0e01-0010-2da1-9bcc452c2... , 4800 / 48XX is mentioned as SNC Secured Gateway port which in my case is not opened.

I have raised a request to open the port. Let's cross the finger once that port is opened if the connection works or not.

Anyways, thanks for your prompt response.

Regards,

Sourav
