Hi expert,

I having problem on my PIX 515E. I have no problems when the PIX only have 2 interfaces (Outside and Inside). After i add additional Ethernet card (for DMZ), I start having problem after i add the access-list.

Before I add the access-list, I need to created NAT first.

I had created 2 NAT.

1) From Outside to DMZ.

2) From DMZ to Inside.

After that, I start add a access-list from DMZ interface to outside interface and click on apply. When i edit the access-list for checking, i saw the access-list is from DMZ interface to inside interface.

I not understand why the outside interface will automatic changed to inside interface. Does any expert know about this?

Please help. Thank you
