VPN Tunnel Established but no Traffic

We have established a Lan2Lan VPN tunnel with a remote site, using IPEC. Looking for some insight to start troubleshooting.

Re: VPN Tunnel Established but no Traffic

do "sh cry isa sa" to verify whether the tunnel is fully established. for a normal tunnel, "qm_idle" should be shown.

do "sh cry ips sa" to verify whether any traffic is being encrypted and/or decrypted.

with a pix, verify whether the command "sysopt connection permit-ipsec" is enabled.

with a router, verify whether the inbound acl is permitting the traffics, such as the remote network to local network.

for further assistance, please post the entire config with public ip masked.
