Tunnel si VPN no

[angelo.val]

Ciao a tutti, questo è il mio primo post dopo aver tanto sbirciato all'interno del forum.

Naturalmente sono alle prese con una VPN che non ne vuol sapere di funzionare ( o forse non riesco a capirla bene... )

La VPN termina su un PIX 501 e sia con il client Cisco che con quello Windows viene stabilita la connessione, ma poi non è possibile raggiungere la lan (\\indirizzoIP) o aprire sessioni telnet.

Penso che il problema sia nel nat ma purtroppo non riesco a venirne a capo.

Grazie anticipate per il vostro aiuto.

grazie per la risposta velocissima, ho fatto la correzione ma purtroppo ancora non va.

Ho provato a fare un pò di debug, ma non sono venuto a capo di nulla.

Alla fine dopo un configure factory-default ed una riconfigurazione passo-passo sono riuscito a sbloccare l'accesso con il client microsoft, purtroppo l'accesso con il client cisco continua a non andare. Per ora va bene così, ma appena mi sarà possibile riproverò.

Grazie per l'aiuto.

Ho paura che il problema sia proprio la presenza sullo stesso fw delle 2 vpn (ipsec e pptp). Posso dire con certezza che possono coesistetre senza problemi, però, almeno per test prova a levarne una e provare

sembra che la cosa si sia risolta con un
