ipsec Sites with same subnet

i' trying to connect one head office to multiple branch offices but some of them have the same subnet like

head office 192.168.44.0/23

branch office 1 192.168.2.0/24

branch office 2 192.168.1.0/24

branch office 3 192.168.2.0/24

The set up of the 2 ipsec from hq to 1 and 2 are ok, using this kb https://community.sophos.com/kb/en-us/123305 on the setting of the ipsec on the branch 3 in local subnet i created the 192.168.10.0/24 and in the natted lan i put his subnet 192.168.2.0/24.

The vpn from hq to bo 3 is estabilished and i can ping from branch office 3 to any ip in the hq subnet. When i try to ping from the head office to bo 3 using the natted ip (ping 192.168.10.55) it work but suddently the ping from bo 3 to hq stop working and it stop also the internet connection.

How can i configure the ipsec without changing the subnet in bo 3?

Thank you
