Help with a Nat rule in ASA Software Version 8.2

So i need to add this NAT rule in one of our new ASA devices

I successfully added it on one side but its running a older version of the firmware

nat (Inside,Outside) source static SHF-BRKLYN-LAN_LOCAL SHF-BRKLYN-LAN_LOCAL destination static SHF-NY-LAN_LOCAL SHF-NY-LAN_LOCAL

Open in new window

Both Actually

I want to upgrade the firmware but i prefer to do it in the weekend

How can i setup a nat like this in 8.2?

Thanks in advance
There have been few changes in how NAT commands are defined in ASA NAT 8.3+ have a look at this document.

For your upgrade you need to upgrade from 8.2 to 8.4 and then to 9.1, cli commands for upgrade are listed here...

I am assuming that this rule pertains to a VPN tunnel.

If it does, this is done much differently in 8.2 code.   In 8.2 code you would create a no nat rule that would include an ACL like this:

access-list NO-NAT extended permit ip x.x.x.0 y.y.y.0

y.y.y.0 = SHF-NY-LAN_LOCAL

then you need to apply it to what is referred to as a NAT 0 statement:

nat (inside) 0 access-list NO-NAT

So what this does is says that when traffic comes in from the inside interface - if it matches the ACL NO-NAT then do not perform a NAT operation when the packet is routed to another interface.

Hope that helps.
