Once you're satisfied with your security setting, click Next. This takes you to the Basic Firewall Domain Name Server Configuration screen, as shown in Figure E. Specify the primary DNS server, and click Next.
HI, I am trying to set up SDM on a 2801. When I get to Fig D medium and High are grayed out. How do I activate them?
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...
