6. The following line should appear:

gds_db 3050/tcp #InterBase or Firebird server

NOTE: The wording of the #comment will vary depending on whether the entry was put there by InterBase or an old
version of Firebird. If that line is not listed, it must be added to the bottom of the list (in the #comment, remove the “or
Firebird” portion).

7. Next, add a new line with an entry for the Firebird service port exclusively, using a different port and service name
(the port number may be any valid port of your choosing):

fb_db 3051/tcp #IFirebird server

8. Click on File > Save to save the changes.

9. Reboot the PC for the changes to take effect.
