VPN tra Netgear e PIX

mannybiker · 30-10-2006, 14:32

Ho bisogno di creare una VPN tra un router Netgear DG834G e un Cisco PIX 515.
Ho provato a seguire le istruzioni riportate sul sito della Netgear ma niente da fare... alla fase 2 dell'apertura del tunneling si blocca.

Nel log del Netgear trovo questo:

Wed, 2006-10-25 17:55:12 - [ITS] initiating Main Mode
Wed, 2006-10-25 17:55:13 - [ITS] ISAKMP SA established

Sul PIX il comando debug crypto ipsec dice:

ho provato con mille formati di criptazione (3des,md5,sha,des) ma non credo sia dovuto a questo perché la prima fase dell'ISAKMP va a buon fine.

Preciso che l'indirizzo del Netgear è dinamico per cui il PIX ha una configurazione:

crypto dynamic-map netgear 10 match address 160
crypto ipsec transform-set netgear esp-3des esp-md5-hmac
crypto map twc 60 ipsec-isakmp dynamic netgear
isakmp key ******** address 0.0.0.0 netmask 0.0.0.0 no-xauth no-config-mode3

cosa mi posso ancora inventare????????

Grazie!!!!
