Ciao a tutti, ho una vpn fatta con due ASA5505, il tunnel viene stabilito ma non riesco a fare ping tra le macchine interne alle rispettive LAN, l'errore che ho è il seguente:

Teardown ICMP connection for faddr 192.168.0.100/0 gaddr 192.168.1.159/512 laddr 192.168.1.159/512
Built outbound ICMP connection for faddr 192.168.0.100/0 gaddr 192.168.1.159/512 laddr 192.168.1.159/512

La configurazione che uso è:

Non riesco proprio a capire dove sbaglio !?
