Hi,
Our database server which is out of DigitalOcean is configured to allow incoming connections from fixed Floating IPs reserved in DigitalOcean.
We have a load balancer (out of DigitalOcean) and few app/web nodes having floating IPs attached. Load balancer is using floating IPs of app/web nodes within it’s backend configuration and all of this is working great except the database connection from app/web node to our database server which is being rejected as it will not come via Floating IPs.
So, A) How can we configure our droplet to use assigned Floating IPs on outgoing connections for all ports & protocol? B) Or, how to use same IPs for outgoing connection? Like “Incoming via Main IP > Outgoing via Main IP” OR “Incoming via Floating IP > Outgoing via Floating IP”
We are using Ubuntu 18.04

Floating IPs are not seen by the droplet they are added to. Instead the droplet sees a local IP that is the Floating IP’s anchor IP. This allows communications back through the floating IP by routing the communication on an internal network out to the Floating IP. For any services that you need to listen or communicate on the Floating IP you’ll want to configure them to use the Anchor IP.
