Connecting to Postgres database on Amazon AWS RDS

Hello,

We have a postgres database on an Amazon RDS server that we'd like to connect to.

The routing table for the RDS must be updated to allow the IP address of any client trying to connect to it.  But I don't see an obvious way to make this work with domo (since I don't know what IP address it will be connecting from).  What is the recommended method here?

I found chartio accomplishes this with an ssh tunnel ( https://chartio.com/resources/tutorials/connecting-to-a-database-within-an-amazon-vpc/ ) but I couldn't find a similar method when searching through the domo forums or help.

Thanks in advance!
