Bypassing VPN for HANA to connect ECC.

Hi All,

I have ECC in the client network accessing it through VPN. I have HANA DB in the external network. I am connecting a HANA table to an ECC Table.How can I connect by skipping the VPN Connection or Can I make one time connection to an HANA table from ECC to make the HANA table realtime. Kindly suggest.
