To enable traffic initiated from a low level security to travel to a high security interface you will normally use static commands, so, for example, if you want a server on the inside with IP address 10.1.1.1 to be reachable from the dmz interface on the same address you would have to add the command:
static (inside,dmz) 10.1.1.1 10.1.1.1
and of course the appropiate access-list bound to the dmz inteface, for example:
access-list dmz-in permit ip any host 10.1.1.1
access-group dmz-in in interface dmz
nat and global statements are normally only needed to enable traffic initiated from the higher level interface. So, if you want people on the inside to connect to servers on the dmz, without translation you would have to add something like:
Yes, "outside" key word is needed from lower to higher security nat/global (i.e., from outside to inside, dmz to inside etc).
Regarding second question, It depends on your requirement. Pl. keep in mind that nat 0 will come before static and nat. When you use, "nat 0 network", this will work one direction that is from higher to lower, but with ACL option it works on both direction so you don't need a static, it will just by-pass the whole nat engine on both direction traffic.
Q1) Can someone please confirm the order of nat/static command processing....Is it nat 0 acl, nat 0, static, nat ? where nat 0 acl is the first command processed and nat is the last command processed.....
Q2) Does the nat/static command processing order change depending on whether traffic originated from a less secure interface to a more secure interface?
Q3) Can I have a sample config of outside NAT? I cant get it to work!!!!
