PIX 501 firewall configuration - Guidelines

Guidelines for configuring a PIX 501 firewall.

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 1.1.1.0 with a 255.255.255.0 subnet mask. The outside IP address for this PIX should be 1.1.1.1.
  • 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 1.1.1.2.
  • Users only need access to port 80 (Web browsing).
  • The default route for the outside (Internet) network will be 1.1.1.254.
