SAP PI - access third party files over SSL VPN

[Former Member]

Hi Guys,

We are to develop interface in SAP PI 7.11. The requirment is to access a third party system and fetch files from there.

The issue is, the third party network can be accessed over SSL VPN.

I have implemented FTPS and i understand SFTP. But how is SSL VPN different from these two?

Thanks and Regards,

Sudeep

All VPN I have worked with are VPN over IPSEC, what is transparent for software, because the secure network is stablished at MAC layer, and thus is transparent from the transport (TCP, UDP).All connection management, stablishment, etc. is performed by the operationg system. 

SSL VPN seems to be a VPN a transport layer, so you have to setup TLS. I don't know if PI is ready for that, but it looks like if you need to develop special communication channel in java or similar.

Hi Sudeep,

As far as i know, to work with SSL VPN  you would need to configure FTPS in PI, check Raja Sekhar Reddy's blog  http://scn.sap.com//people/rajasekhar.reddy14/blog/2010/04/13/how-to-configure-ftps-in-file-adapter

With FTPS you will have the secure SSL channel to use the VPN.

Hi Vila, thanks for replying.

I have read the document, but nowhere it mentions anything about SSL VPN.

I have implemeneted FTPS in a company network (no VPN). But i dont know what the change or significance a SSL VPN network has.
