do you REALLY have 172.16.1.5 and 10.0.1.15 as your IP addresses?
If so there is no way you can be reached from the outside..
unless you have made an agreement with the ISPs to forward some address/port
to you.
They are doing NAT on your outgoing sessions as it is already..




 sorry for my bad explanation
