Destination nat and pptp server

please how can i configure destination nat and pptp in one mikrotik i configured it each separately and it works correctly but when i configure both to gather ( pptp and destination nat ) my pptp server refuse the connection

please how can i configure it

Route PPTP serve ip over original default route.

thanx for replaying

what do you mean in that (Route PPTP serve ip over original default route.) my internal Defaultgatway is 10.10.10.1
and my web server ip is 10.10.10.10 so how can i route the pptp

well thanks for replay..

i will explain my configuration now

i have two Ethernet ( Int,Ext )

Int configuration
ip : 10.10.10.1 ( add ip address=10.10.10.1/24 interface Int )

Ext configuration ( my static ip )
ip : 212.175.52.186 ( add ip address=212.175.54.186/30 interface Ext )

then i have specified my gateway
Gateway : 212.175.54.185 ( ip route> add gateway=212.175.54.185 )

then i configure it as a masquerading nat
ip firewall nat> add chain=srcnat action=masquerade out-interface=Ext

then i started my pptp configuration
ppp secret> add name=ex service=pptp password=lkjrht local-address=10.10.10.1 remote-address=10.10.10.220
interface pptp-server> add name=FromLaptop user=ex
interface pptp-server server> set enabled=yes
interface ethernet> set Int arp=proxy-arp

so this is my configuration i did this then my problem was i could`t establish a pptp connection from out side then i test it from inside its work correctly please help me my manager need establish a pptp connection fro US and he is waiting me..

Guesse 212.175.54.185 is a publick ip, is 212.175.52.186 one as well? What i am thinking is that your server PPTP IP is not reachable from internet. Routing problem. The ip’s for local and remote will work nice on network because network knows how to get to them, internet have got no idea unless they are publick IP or nat from a publick ip.
