Setting up a reverse proxy server for fixed IP address on Digital Ocean

Axolo, an integration that streamlines code review processes, migrated from Heroku to Digital Ocean. However, one issue they faced was Digital Ocean Apps not supporting a static IP address, which is necessary for some enterprise servers requiring IP address whitelisting. To resolve this, Axolo considered two alternatives: transitioning to a Digital Ocean Droplet or setting up a reverse proxy server. They ultimately decided on the latter and chose to use a third-party service, QuotaGuard.com, due to its simplicity and effectiveness. This solution allowed them to maintain their server's integrity and security while providing a fixed IP address for enterprise communication.
