I have a site-to-site VPN with IP schemes of Location E 192.168.100.x and Location W 192.168.101.x - a third party vendor is requiring/requesting ping for their VOIP system. I can ping from Location W to Location E but not vice versa. I can ping the router inside interface (192.168.101.254 I believe) but not any of the hosts on the inside. Please help. I've checked all my ICMP references and they are as follows:

policy-map type inspect sdm-permit-icmpreply
