I am setting up a VPN between 871 router and ASA 5505 for the first time and having some issue. I have attached my network diagram as well with the configuration of 871 and ASA. Although VPN tunnel is coming up i.e. sh crypto isakmp sa shows QM_IDLE and ipsec SA exchange is successuful as well but none of the machine can access each other. Please help as I am in desperate need to get it working.
Thanks you all,
Looks like you are missing some required configuration. See the below link..
