Before beginning the configuration, you have some guidelines that you need to follow. Here they are:
- All passwords should be set to "cisco" (in reality, you make these whatever you want)
- The inside network is 10.0.0.0 with a 255.0.0.0 subnet mask. The inside IP address for this PIX should be 10.1.1.1.
- The outside network is 126.96.36.199 with a 255.255.255.0 subnet mask. The outside IP address for this PIX should be 188.8.131.52.
- You need to create a rule to allow all inside users on the 10.0.0.0 network to do port address translation and connect to the outside network. They will all share the global IP address 184.108.40.206.
- Users only need access to port 80 (Web browsing).
- The default route for the outside (Internet) network will be 220.127.116.11.
