In questo documento viene illustrata una configurazione IPsec che include le funzionalità da gateway a gateway e da utente remoto. Con l'autenticazione estesa (Xauth), il dispositivo viene autenticato tramite la chiave precondivisa e l'utente viene autenticato tramite una richiesta di verifica di nome utente e password.
Nessun requisito specifico previsto per questo documento.
Le informazioni fornite in questo documento si basano sulle seguenti versioni software e hardware:
PIX Firewall versione 6.3(3)
Cisco VPN Client versione 3.5
Cisco Secure ACS per Windows versione 2.6
Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.
Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.
Nell'esempio, è presente un tunnel IPsec da gateway a gateway dal PIX remoto al PIX dell'hub. Questo tunnel crittografa il traffico dalla rete 10.48.67.x dietro il PIX remoto alla rete 10.48.66.x dietro il PIX dell'hub. Il PC su Internet può formare un tunnel IPsec attraverso l'hub PIX alla rete 10.48.66.x.
Per utilizzare la funzionalità Xauth, è necessario innanzitutto configurare il server di autenticazione, autorizzazione e accounting di base (AAA). Usare il comando crypto map client authentication per comunicare al firewall PIX di usare la richiesta Xauth (nome utente e password RADIUS/TACACS+) durante la fase 1 di IKE (Internet Key Exchange) per autenticare IKE. Se Xauth ha esito negativo, l'associazione di protezione IKE non viene stabilita. Specificare lo stesso nome del server AAA nell'istruzione di comando crypto map client authentication specificata nell'istruzione di comando aaa-server. L'utente remoto deve eseguire Cisco VPN Client versione 3.x. o successiva.
Nota: Cisco consiglia di utilizzare Cisco VPN Client 3.5.x o versioni successive. VPN Client 1.1 non funziona con questa configurazione e non è compreso nell'ambito di questo documento.
Nota: Cisco VPN Client 3.6 e versioni successive non supporta il set di trasformazioni des/sha.
Per ripristinare la configurazione senza Xauth, usare il comando no crypto map client authentication. La funzione Xauth non è attivata per impostazione predefinita.
Nota: la tecnologia di crittografia è soggetta ai controlli sulle esportazioni. È tua responsabilità conoscere la legge relativa all'esportazione della tecnologia di crittografia. Per ulteriori informazioni, consultare la home page Bureau of Export Administration. In caso di domande relative al controllo sulle esportazioni, invia un'e-mail a export@cisco.com.
Nota: in PIX Firewall versione 5.3 e successive, sono state introdotte porte RADIUS configurabili. Alcuni server RADIUS utilizzano porte RADIUS diverse da 1645/1646 (generalmente 1812/1813). In PIX 5.3 e versioni successive, le porte di autenticazione e accounting RADIUS possono essere modificate in altre rispetto alle porte 1645/1646 predefinite utilizzando questi comandi:
aaa-server radius-authport # aaa-server radius-acctport #
In questa sezione vengono presentate le informazioni necessarie per configurare le funzionalità descritte più avanti nel documento.
Nota: per ulteriori informazioni sui comandi menzionati in questo documento, usare lo strumento di ricerca dei comandi (solo utenti registrati).
Questo diagramma utilizza linee verdi e nere in grassetto per indicare i tunnel VPN.
Nel documento vengono usate queste configurazioni.
Nota: nell'esempio di questo documento, l'indirizzo IP del server VPN è 209.165.200.225, il nome del gruppo è "vpn3000" e la password del gruppo è cisco.

Fare riferimento alla sezione "Configurazioni" di Configurazione di PIX su PIX e VPN Client 3.x per informazioni dettagliate su come configurare il client VPN. Inoltre, fare riferimento a Come aggiungere l'autenticazione AAA (Xauth) a PIX IPsec 5.2 e versioni successive per ulteriori informazioni sulla configurazione dell'autenticazione AAA su PIX IPsec.
Le informazioni contenute in questa sezione permettono di verificare che la configurazione funzioni correttamente.
Lo strumento Output Interpreter (solo utenti registrati) (OIT) supporta alcuni comandi show. Usare l'OIT per visualizzare un'analisi dell'output del comando show.

Nota: consultare le informazioni importanti sui comandi di debug prima di usare i comandi di debug.
I debug devono essere eseguiti su entrambi i router IPsec (peer). Le associazioni di protezione devono essere cancellate in entrambi i peer.

debug crypto ipsec: visualizza gli errori durante la fase 2.
debug crypto engine: visualizza le informazioni provenienti dal crypto engine.
clear crypto isakmp sa: cancella le associazioni di sicurezza della fase 1.
clear crypto ipsec sa: cancella le associazioni di sicurezza della fase 2.
debug radius [session] | tutto | nome utente]: disponibile in PIX 6.2, questo comando registra le informazioni sulla sessione RADIUS e gli attributi dei pacchetti RADIUS inviati e ricevuti.
debug tacacs [session|user <nome_utente>]: disponibile in PIX 6.3, questo comando registra le informazioni TACACS.
debug aaa [authentication|authorization|accounting|internal]: disponibile in PIX 6.3, mostra le informazioni sul sottosistema AAA.
Nota: talvolta, quando la negoziazione IPsec ha esito positivo, non tutti i debug vengono visualizzati sul PIX a causa dell'ID bug Cisco CSCdu84168 (solo utenti registrati), che è un duplicato dell'ID bug Cisco interno CSCdt31745 (solo utenti registrati). La questione non è stata ancora risolta al momento della stesura del presente documento.
Nota: a volte la VPN IPSec dei client VPN potrebbe non terminare sul PIX. Per risolvere il problema, verificare che il PC client non disponga di firewall. Se sono presenti firewall, verificare che le porte UDP 500 e 4500 siano disabilitate. In questo caso, abilitare IPSec su TCP o sbloccare le porte UDP.
