Hi,
Host behind the router can ping the network behind the ASA5505, from ASA5505 you can't reach the router, please feel free to correct me if wrong.
Can you make sure when you run a continuous ping from ASA to the network behind router, do you see encrypts growing in numbers [execute the command show crypto ipsec sa peer " public ip address of router" to see the encrypts/decrypts] .
I want to make sure that the traffic is not going in some other tunnel when initiated from ASA.
Also, make sure you have NAT 0 statement correct on ASA , if exempting the traffic from NAT.
Can you please share the configuration from both ASA and router so that i can make sure basic configuration is in place?
Regards
M
