Reflexive ACL and IPSec VPN tunnel

Hello,

In my topology (attached below) I've configured an IPSec tunnel successfully and all hosts can ping each other with no problems.

My goal is: - Host 3 (192.168.3.1/24) can ping Host 2 (172.16.2.1/24)

            - Host 2 can ping Host 3

            - Host 1 (192.168.4.1/24) can ping Host 3

            - Host 3 cannot ping Host 1

            - Host 1 can ping Host 2

            - Host 2 cannot ping Host 1

I configured the following ACLs on the router R1:

ip access-list extended out-host 3

permit ip 172.16.2.0 0.0.0.255 192.168.3.0 0.0.0.255

permit ip 192.168.4.0 0.0.0.255 192.168.3.0 0.0.0.255 reflect mirror

----------------------------

ip access-list extended out-host 1

evaluate mirror

----------------------------

And this one on the router R2

ip access-list extended out-host 2

permit ip 192.168.3.0 0.0.0.255 172.16.2.0 0.0.0.255

permit ip 192.168.4.0 0.0.0.255 172.16.2.0 0.0.0.255 reflect mirror

--------------------------------------

Host 3 and 2 can ping each other successfully.

Host 3 cannot reach Host 1 (success)

but Host 1 cannot reach Host 2 and I know that the reflexive ACL is unable to pass through the IPSec tunnel so what should I do to make it work ?

Thank you.
