[nsp] translating the port

[Rajeshbansal9 at aol.com]

Hello,

Is there any way in 7600 just to translate the destination port of a packet. 
So if the 7600 receives a packet that is destined to port 25, have it change 
it to something else and maintain the session entry. Sort of NAT but maintaing 
the address but just changing the destination port.

Thanks
