SMB/Cifs versus WAF/Webdav

RemoHehlert

Hallo werte Forengemeinde,

folgenden Konstellation:

Test 1: SMB/CIFS

PC (Win10) => LAN => FW1 => FW2 (SG230) > NAT zu NAS Server

Test 2: WAF/WEBDAV

PC (Win10) => LAN => FW1 => FW2 (SG230) > WAF zu NAS Server

 

Öffne ich eine Datei (Word / Excel / PDF / TXT) über Testfall 1 dauert das aufrufen bis zum vollständigen Anzeigen sehr lange: (400KB über. 10 Sek).

Die gleiche Datei über Testfall 2 (Web Application Firewall und Webdav) dauert hingegen ca. 2 Sekunden)

 

Mit anderen Worten, ein privat Cloud Zugirff auf den den gleichen NAS Server ist sehr schnell hingegen über SMB/CIFS sehr langsam.

IPS hatte ich mal abgeschaltet, hat aber keine Änderung gebracht.

 

Hat jemand eine Idee wie ich diesem Problem auf die Spur kommen kann?

 

Besten Dank im Voraus

    I am guessing the problem is in session setup.   Use Wireshark to look for problems with name resolution or priblems with SMB connection.    

    For example, I wonder if it is attempting SMBV2 on port 445 without success, then failing over to port 139 and SMB v1.

    SMB may also be adding overhead as it attempts authenticate, even if the final disposition is to use the Guest accoount.
