Problem with src-nat - no received packe (have Tx but no Rx )

Hi everybody
I have created a pptp connection on RB v6.43.12 and got the ip address and wanted to route my internal network through pptp-out interface

I have tested two way:
1- adding Default Route Distance of the pptp-out lower than other routes
2- using srcnat (ip firewall nat add chain=srcnat src-address=192.168.1.0/24 action=src-nat to-addresses=x.x.x.x out-interface=pptp-out)

but in both ways I have Tranfer Packet but no Received Packet

By the way, the pptp conncetion works in windows without any problem

what could be the problem !
thanks in advance.

post config
/export hide-sensitive file=yourconfigfeb28

thanks , This is my config
yourconfigfeb28.rsc (2.74 KB)

I am not very familiar with pptp or ppoee etc…
but this looks wrong.
add action=masquerade chain=srcnat comment=“masquerade hotspot network”
src-address=172.16.0.0/24
it should be
add action=masquerade chain=srcnat comment=“masquerade hotspot network”
src-address=172.16.0.0/24 out-interface-list=WAN
(not sure if the src address is correct to put in there but as I stated i am not sure but you do need to state the outgoing interface).
