Create DBLINK from ATP to onprem on port different than 1522

Hello,

I tried to create a dblink from an ATP instance to a onprem db, and it works fine (mTLS) on port 1522.

However if I try to change the port (eg: 6666) the connection times out with a '12170. 00000 - "TNS:Connect timeout occurred"'

I can't even see any packet reaching the onprem firewall.

Is it supported to create dblink to a port different than 1522 ?

Where can I configure an ACL, if it's possible ?

BEGIN

 DBMS_CLOUD_ADMIN.CREATE_DATABASE_LINK(

  db_link_name => 'DBLINK1522',

  hostname => 'nat-to-onprem-db',

  port => '1522',

  service_name => 'dbservice',

  ssl_server_cert_dn => 'CN=testwalletserver',

Howdy, Stranger!
