The "Table 1.3. Capsule incoming traffic" must consider port 9090 for Global Registration Method Port 9090 is mentioned for various reasons in the said table but It's missing the declaration for /register endpoint. If a client system would need to be registered with an external capsule server via Global Registration method, Then port 9090 should be opened from Client to Capsule server or else the /register endpoint cannot be accessed over port 443 of a capsule.

The same needs to be fixed\added in the documentation of the currently supported version of satellite\capsule i.e. 6.11 and 6.12.
