Il problema è che la VPN con il client Cisco VPN Dialer sale, mi chiede l'autenticazione e mi chiude il lucchetto, inoltre mi assegna correttamente l'IP dal pool che ho configurato.
Il problema è che non riesco ad accedere alla rete remota via VPN (192.168.45.0/24). Mentre la configurazione dello split-tunnel pare che funzioni correttamente.
Per dovere di cronaca, il firewall è dietro ad un router telecom Alice del menga... (non ci posso fare nulla) che natta verso l'ASA il traffico diretto alla 500 UDP ed alla 4500 UDP sull'IP pubblico assegnato al router sull'interfaccia ADSL.
DOMANDONE: come mai non riesco ad attraversare il tunnel? E come mai nel log dell'ASA non compare nulla di nulla in merito al traffico che sto cercando di generare?
Grazie a tutti in anticipo!
