Titolo: VPN client con PIX

Ciao a tutti,
vi disturbo per un problema che mi assilla da un po' di tempo e
riguarda la connessione con vpn client su un pix 515.
La connessione avviene senza qualsiasi tipo di problema ma non riesco a
tunnellizzare traffico sulla vpn.
Facendo un po' di debug ho riscontrato questo log:
crypto_isakmp_process_block:src:ip_src, dest:ip_dst
spt:500 dpt:500
ISAKMP (0): processing NOTIFY payload 36136 protocol 1

ISAMKP (0): received DPD_R_U_THERE from peer ip_src
ISAKMP (0): sending NOTIFY message 36137 protocol 1
return status is IKMP_NO_ERR_NO_TRANS.
La configurazione del PIX e' la seguente:

Per intenderci se faccio qualsiasi tipo di traffico da vpn client alla
sottorete dell'interfaccia inside non ottengo nessuna risposta, ping,
tcp, udp...ecc....
La prima volta l'ho configurato via terminale, poi credevo di sbagliare
qualcosa nelle isakmp e ho eliminato la cfg e rifatta con PDM, ve ne
sarete accorti presumo :-)
Un'altra cosa la versione del client è la 4.0.5.
A qualcuno leggendo la cfg viene qualche idea?
Vi ringrazio anche solo per aver letto la mia richiesta di aiuto :-)
Ciao
Paolo

ciao,
prova ad aggiungere
isakmp nat-traversal 20
 access-list vpn_splitTunnelAcl permit ip 192.168.25.0 255.255.255.0
192.168.32.0 255.255.255.0 
bye

non ci crederai ma ci ho già provato...
nada de nada...
comunque grazie per il suggerimento...

Ciao!
Ho risolto, non immaginerete come.... re-installando il client vpn....
mi sembrava che dovesse funzionare, capperi!
Grazie davvero comunque!!
