Static NAT w/Port Translation

[RICHARD DUNN]

Sorry, if this is a newbie kind of question, but I've been a networker for quite a while but this issue is a little confusing to me.

I have 10 phone switches on 10 different subnets aand each has a unique port number to which I connect, all behind an ASA 5510 Ver.8.4(1). What I'd like to do is combine one of my public addresses on the outside interface with the unique port number for each of the internal devices. Example: 174.x.x.129:21006 = 10.2.2.56:21006, 174.x.x.129:22006 = 1.2.3.144:22006, 174.x.x.129:23006 = 10.2.4.67:24006, etc. I'm not even sure where to begin. Would I make individulal network objects for my internal hosts or one network object group? Same question for the outside address. Thanks in advance for any help.

This appears to be a static tcp pat requirement, have you read the configuration guide for your ver of iOS?

Hi Richard,

Heres a sample config of what you'll need:

object network public_ip

host 174.1.2.3

object network private_ip

host 10.1.1.1

object service port_21006

services udp destination eq 21006

nat (outside,inside) source static any any destination static public_ip pivate_ip services port_21006 port_21006

and you can do it similarly for rest of the ip's as well.

Hope this helps

Thanks,

Varun
