Based on the list of ports and services provided, here is a detailed summary that can be used to set up firewalls, routers, and other network equipment to ensure proper operation of the required services.
The configuration considers inbound and outbound ports for different services/protocols.
- Inbound: Ports that must be open to allow incoming connections.
- Outbound: Ports that must be open to allow outgoing connections.
- Security: Be sure to implement appropriate security measures to prevent unauthorized access.
- Internal communications: Some ports are used only for internal communications and should not be blocked by local firewalls.
This diagram can be used to properly configure the firewall and other network equipment to ensure optimal operation of the various services and protocols listed.
