Esempio di configurazione dei profili ISAKMP da LAN a LAN e client EzVPN su PIX con accesso client VPN a un router hub

Introduzione

In questo documento viene fornita una configurazione di esempio per la configurazione dei tunnel IPsec con profili ISAKMP su un router hub con due siti remoti PIX. Un sito remoto PIX è costituito da una connessione LAN a LAN e l'altro da una configurazione della modalità di accesso remoto EzVPN. Il router hub è configurato per l'autenticazione locale per i tunnel EzVPN e per l'autenticazione RADIUS per il client VPN software.

Configurazione client VPN

Completare questa procedura per configurare il client VPN.

1. Avviare il client VPN e creare una nuova connessione con i parametri di voce di connessione necessari.

   

2. Una volta creata la voce di connessione, fare clic su Connetti e autenticarsi con i parametri utente configurati sul server RADIUS.

   

Verifica

Le informazioni contenute in questa sezione permettono di verificare che la configurazione funzioni correttamente. Per ulteriori informazioni sulla verifica e la risoluzione dei problemi, consultare il documento sulla risoluzione dei problemi di sicurezza IP - descrizione e uso dei comandi di debug. In caso di problemi o errori del client VPN, fare riferimento allo strumento di ricerca degli errori della GUI del client VPN.

Alcuni comandi show sono supportati dallo strumento Output Interpreter (solo utenti registrati); lo strumento permette di visualizzare un'analisi dell'output del comando show.

• show crypto isakmp profile: visualizza tutti i profili ISAKMP e le relative configurazioni sul router.

• show crypto isakmp key: visualizza tutti gli anelli di chiave e le relative chiavi già condivise. Utilizzare questo comando per verificare la configurazione del keyring di crittografia sul router.

• debug crypto ipsec: visualizza le informazioni sulle negoziazioni della SA IPsec sul router.

• debug crypto isakmp: visualizza l'associazione di sicurezza ISAKMP generata e gli attributi IPsec negoziati. Durante la negoziazione della SA ISAKMP, il PIX potrebbe ignorare diverse proposte come "non accettabili" prima che ne venga accettata una. Una volta concordata l'associazione di protezione ISAKMP, gli attributi IPsec vengono negoziati.
