Hi, I am building an Ipsec vpn tunnel between two sites and the tunnel using an ADSL router and two Cisco 2921 ISR G2 routers (a redundant pair). I am using ipsec stateful failover to make the two routers redundant. The tunnel goes up and the failover works fine as well. I have one issue though, I cannot ping from one lan to another. Would you please have any suggestion as to what the issue might be ? Thanks in advance for your answer.
I have this problem too.
