Goal

E-Business Suite 12.2 Applications Technology Stack, Advanced Configurations Demilitarized Zone (DMZ) related issues

When using https servers behind a proxy server in a 12.2 DMZ configuration, the instance calls Web services on the first apps node but no web services are called on the second applications tier node.

For example if the the configuration  includes the following footprint:

1 Database tier in "Secure" zone
1 Concurrent Manage server in "Secure" Zone
1 Admin server in "Less Secure" zone which is behind a firewall.

In summary there is a firewall between the internal only nodes, eg. the Secure and Less Secure internal zones.

All tiers are Internal and no external connections exist.

Provide a reference of which ports should be opened in the firewall for DMZ configurations with multiple nodes (DB port, ssh port, WLS port).
