ho configurato un pix 506 per accettare le richieste di connessioni dai i client vpn cisco, solito ho creato il pool ho creto le regole di nonat e split tunnel.... tutto funziona benissimo pingo e riesco ad accedere a tutti gli host della rete e viceversa ma non riesco a pingare lo stesso pix ed eventualmente ad accedervi tramite telnet. Tutto ciò funziona invece perfettamente dalla rete interna. Che regola posso essermi dimenticato....... ecco la conf
