nat,global & dmz mixed up!


i am try to configure pix 515 with in,out and one dmz. the webserver in dmz is connected thru wan link. here is my nat and global

global (outside) 1 203.1xx.1xx.x

global (outside) 2 interface

global (DMZ1) 2 netmask

nat (inside) 2 0 0

nat (inside) 1 0 0

only users in network can access dmz, but they also need access to internet thru outside. with this config they can access it. but there is one more network which needs access to this dmz if i put nat:

nat (inside) 2 202.9.20x.0 0 0

they can access the dmz but CANNOT browse internet thru outside. if i remove it they can access the net but not dmz.

Re: nat,global & dmz mixed up!

Check if there are two seperate return paths for both the NATstatements. The order of NAT is explained in the following document which might give you an idea.


Re: nat,global & dmz mixed up!

basically all inside hosts need access to both internet and dmz, right? and you want inside hosts to be NATted into different public ip when browsing internet, right? also ,assuming no traffic will be initialised from dmz to inside

no global (DMZ1) 2 netmask

static (inside,DMZ1) netmask 0 0

you don't need access-list if you haven't got one for inside interface. if you do, then you have to do

access-list xxx permit ip
