Cisco ASA 5505, VPN RA Problem mit Traffic, No translation group found
Hallo Administrator-Gemeinde,
momentan bin ich mit unserer ASA 5505 am Arbeiten und habe die Radius-Protokoll-Authentifizierung am IAS-Service unseres AD-Servers eingerichtet.
Somit können sich die User mit Ihrem Domänen-Kennwort auch via VPN einwählen, sofern sie in der entsprechenden Gruppe eingeordnet sind.
Ich stehe vor dem Problem das kein Traffic von den Eingewählten RA-Clients (Cisco SoftwareVPN-Client 5.0.x) an das interne Netz weitergeleitet wird.
Phase 1 und Phase 2 werden jedoch erfolgreich aufgebaut und ASDM meldet eine erfolgreiche Verbindung der Clients.
Die Debugging-Logs sagen z.B für einen FTP-Zugriff.
3 Nov 25 2008 11:35:21 305005 ad_server No translation group found for tcp src wan2:172.16.1.1/1216 dst inside:ad_server/21
Wo und wie stelle ich eine Translation-"Group" ein?
Unten stehen die Configuration der ASA.

Hallo DuckY,
vielen Dank für Deine Antwort, ich verstehe aber leider noch nicht ganz wie die Regel lauten muß.
Prinzipiell laufen doch die VPN-Client mit der Adresse 172.16.1.0/24 an der WAN2-Schnittstelle auf.
Die Nat Regel sollte dann doch die 172.16.1.0/24 an WAN2 nach Inside (192.168.1.0/24) umschreiben, oder sehe ich das falsch?!
Wenn ich das in diesem Schema in der ASDM eingebe bekomme ich die Fehlermeldung von Überlappenden Adress-Listen, (genauer der vpn_pool)
Irgendwie macht es noch nicht ganz klick, weißt Du vielleicht ein Konfigurationsbeispiel? Ich habe es leider nicht hinbekommen.
Beste Grüße

Du hast vielleicht nur eine kleine Dinge vergessen.
Du musst im jedem Fall ein NAT (NAT Ausgrenzung) Regel konfigurieren für Datenverkehr die passt durch VPN.
Mit diese Kommandos kannst du VPN traffic von NAT ausschließen:
access-list nonat extended permit ip 192.168.1.0 255.255.255.0 172.16.1.0 255.255.255.0
nat (inside) 0 access-list nonat_acl
Könntest du es probieren und rückmelden?
