Configuring Firewall settings for SQL Server

Antonios Chatzipavlis
Friday 28 December 2012

Είναι κρίμα μερικές φορές να ταλαιπωρούμαστε είτε γιατί δεν γνωρίζουμε τα στοιχειώδη είτε έχει κολλήσει το μυαλό και δεν πάει παρακάτω με τίποτα είτε αυτός που τα θυμάται πάντα δεν είναι παρόν και δεν είναι διαθέσιμος την δεδομένη στιγμή για να τον ρωτήσεις και προχωρήσεις παρακάτω.

Για όλα αυτά λοιπόν σήμερα θα σας γράψω κάποια από τα στοιχειώδη που πρέπει να γνωρίζει κάποιος που ασχολείται με τον SQL Server και αφορούν τα TCP/UDP ports των διαφόρων services που έχει αυτός. Ο λόγος απλός και με λέξη κατανοητός firewall settings αγαπητοί συνάδελφοι… Αν δεν περάσεις από αυτό SQL Server δεν βλέπεις…

Η λίστα αυτή είναι η παρακάτω:



Database Engine


Default Instance

TCP 1433

Named Instances

Dynamic / Static

Dedicated Admin Connection

TCP 1434

SQL Server Browser Service

UDP 1434

SQL Server Instances over HTTP endpoint


TCP 443 (SSL)

Service Broker

TCP 4022

Database Mirroring

Custom defined εκτελούμε το παρακάτω για να τα βρούμε

SELECT name, protocol_desc, port, state_desc FROM sys.tcp_endpoints WHERE type_desc=’DATABASE_MIRRORING’;


TCP 1433 (default instance)

T-SQL Debugger

TCP 135



Analysis Services


Default Instance
