Hello all I just achieved my CCNA last weekend, now i'm trying to redo my home network. I currently have 2610XM router that will be routing my internet connection. I have two ethernet ports, one will be bridged from the ADSL modem, to the eth 0/1 interface, and LAN from Eth 1/0. I want to use my Firewall that I have for security as well. I know access-lists in a router are a form of security, but most i'm trying to set my lab up just like a production network in a company Router-->PIX--->Switch. My theory is this, if when I configure the devices will I'm thinking the static ip will be given to me by Bellsouth's servers, and I wouldn't do any ip configuration there, but on the eth 1/0 interface I would set a static IP there, and connect that to the PIX's eth0.
Once I have that configured i'll set a static address on the Ethernet 1 interface as well. Now would I be configing or double NAT or only one NAT rule for this setup?
