How to connect to a other clients in the back end system via HANA cloud connector / HANA cloud platform approach

Hello Experts,

I am trying to access a on premise gateway system within out VPN using the HANA cloud connector approach. I went through all the steps successfully as per the instructions.

Here is the tricky situation I am in right now:

I would like to access the client 400 on our on premise gateway system. But after all the configuration steps, as shown in the pop up below, I am asked to login to the default client which is 100. And I don't see an option to change the client.

is there any option to reroute my system to access 400 client by default ? 

Thanks for your help in advance.

Regards,

Vinay
