Security

Secure your router with Cisco's SDM Firewall Policy Wizard

Figure D

After you've made your selections, click Next. This takes you to the Basic Firewall Security Configuration screen, as shown in Figure D. Choose the level of security for the firewall: High, Medium, or Low.

I chose Medium Security and clicked the Preview Commands button to review the commands this setting would apply. Listing A displays this output.

When you see the output, you'll be glad you didn't have to manually type all those commands.

You would use your ISP's DNS Servers. Your PC or router will get this from DHCP, automatically, from the ISP (or at least you should). If your router does not, you can hook up your PC only, get the IP of the DNS server via DHCP, then connect the router and plug the IP in. I hope that helps!

I see you did the walk-through on SDM 2.4, which defaults to Zone Firewall in the wizard (provided there's not already an 'ip inspect' firewall configured). Previous SDM versions included a firewall wizard, but they configured the classic FW. (SDM 2.4 was the first version to support the Zone-Based Policy Firewall). Many of the firewall configuration options must be found on the "additional tasks" section at the bottom of the left column. However, it beats configuring the Zone FW through the CLI...
