Unfortunately the PIX does not work like peas in a pod as the Router IOS it does not support equal Access List numbering.
It also does NAT in a enormously different agency as okay (especially the elder versions) i.e. You requirement to enjoy a NAT statement even when you are not NATing (It can be pretty confusing)
If you do not know much just about the PIX OS consequently I recommend you try and use the PDM (Web management) make a note of the magazine is specific to the code you are running v6.1 requires PDM 4.1 I believe (need to check)
Once you nouns the PDM it become a point a click to allow NAT and Access Lists here are also some Wizards as capably
By creating an access list
Example:
access-list 101 warranty TCP 10.2.2.2 255.255.255.0 10.1.1.1 255.255.255.0 eq 80
So access-list is the command, 101 is in recent times a identify and you can progress it to anything you want, receipt is another command you can put receipt or deny anything you want, TCP is to indicate that the ports that you want to allow is running underneath TCP or UDP, you can also use IP surrounded by this place if you want to voucher or deny an IP address, consequently you put the source IP address near the subnet shroud later the destination IP address beside its subnet concealing outfit, consequently eq is another command and consequently you can put 80 to indicate what port you want to warranty or you can also can put www.
