we are trying to create Lan to Lan connection between a cisco PIX 506 and a C3020 VPN, when i create traffic for secure destination, i can see in the PIX that the tunnel is trying to up, but when there is no traffic, the ipsec tunnel goes down and when i restart the traffic the tunnel doesn't retry, if i want to recreate the tunnel, i need to reload the PIX 506 and it works for a few minutes.
Can you tell me how to troubleshoot something or what can it be ?
