OCI: Still Cannot Connect to Ports XXXX Even After Adding to VCN Security Rules and IPtables Rules on Oracle Linux 6 (Doc ID 2557732.1)

Last updated on JULY 15, 2022

Applies to:

Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64


Connections to certain ports still fail even when they are allowed in VCN security list/rules, and are also added to IPTables rules for target ACCEPT.

In this particular example, TCP ports 5500 and 5501 are intended to be open to traffic, but are still blocked.
