no i have put the right route on booth side.
i can make a connection from 157.23.17.21 to 195.120.222.1 (nat of 172.16.13.69, i use a polici based nat
but when i make a connection from 172.16.13.69 to 157.23.17.21 i cant be natted behind the same address because i don't use a mip.
for the mip i can't use it because when i try it say "The mapped ip must be in the same subnet as the interface"
