Hi @Priya Naveen,

For OutSystems Cloud:

  • OutSystems provides outbound IP ranges

  • These IPs must be allowed in:

    • Firewall

    • DB security group

    • Network ACL


But you can try below secured way of accessing the same:

  • Create Site-to-Site VPN

  • DB is never exposed publicly

  • Firewall allows traffic only from VPN


Regards,

Sandeep

Hi @Priya Naveen 

When connecting Outsystems to external databases protected by firewalls, there are several network, security, and database considerations beyond just creating the connection string.

The Typical Enterprise Flow:

  1. Obtain Outsystems outbound IPs
  2. Firewall team whitelists them
  3. Open DB port
  4. Verify routing/VPN
  5. Configure SSL if required
  6. Create restricted DB user
  7. Configure connection in Outsystems
  8. Test connectivity, Monitor logs/timeouts
