ASA problem with IPSEC VPN data not passing

Hi

I am facing a starnge problem .

I have attached the diagram that i could make best.

Now problem is that:

I can ping from 172.16.15.0 > 10.10.16.0/24( all the IP address)

I can ping from 172.16.15.0(any ip) > 10.10.16.22 ( single ip pass )

I can ping from 172.16.15.0(any ip) > 10.10.16.X ( all other ip except .22 fails )

I tried extended ping from router interface ip : 10.10.16.254 ( secondary ) to 172.16.15.0 ( all ip) and it is success.

The configuration and ACL ( Both side) seems to be ok, VPN Tunnel is also up thats why the data is passing and pinging.

Also we found that there are ACL hits in the router, But there is no ACL hits in the ASA ,also there is no duplicate ACL so there is no chance of hitting any other ACL.

Also single inteface in the router has been used for LAN as well as WAN and WAN connectivity is via wireless(ISP)

Plz find the config as below , As i can't share all the config and VPN details i am partially sharing the required one.

Try it from CLI, you can see if the action if VPN encrypt or VPN drop.  You should also see an increment on your interesting traffic ACL.

Hi

Thanks to all of you for sharing your ideas.

It seems that the packet for some of the remote device are nt reaching the remote router interface,

It may be a problem and we are planning to test the same.

Also at the remote end my router has oly one inetrface configured for LAN and WAn and Lan ip i have given as seondary and wan ip as primary to same interface.

.22 is a end host connected to the common switch where router and wireless device is connceted.

.22 is able to ping but the other ip cann't able to ping (.21,.23 etc)those are some power rating device, But from the Router LAN interface was able to ping the device the de the

Will disabling proxy arp in the router(remote) side help in this case
