How configure nat with diferent TCP port but the same IP

Hi

I'm traying to configure nat for the same host but with different port translation.

Example:

SRC DST PORT SRC-NAT DST-NAT PORT-NAT
1.1.1.1 2.2.2.2 4000 1.1.1.1 3.3.3.3 4001
2.1.1.1 2.2.2.2 4000 2.1.1.1 3.3.3.3 4002
3.1.1.1 2.2.2.2 4000 3.1.1.1 3.3.3.3 4003
4.1.1.1 2.2.2.2 4000 4.1.1.1 3.3.3.3 4004

I try every nat posibility (static, dynamic, ACL, route-map,...), but nothing work.

Did somebody have any idea how can I configure this type of NAT?

Thnaks in advance.

View this then post your configuration attempt.


Also what is your public address from your ISP?
What is your private address range?


My guess is your trying to do a static nat when you need dynamic nat with port overload.
