I got a CISCO 1800 router. I want to allow a particular domain only. Its clustered so I dont know what the IP address is.
Here is what I need. In cisco routers, I can set the ACL to allow a particular IP. I am setting this up for a corporate using this guide:
For IPs I set something like:
access-list acl_permit permit ip 192.168.32.0 0.0.7.255
However, for some sites which I do not want to block, I need to allow particular domains. So I dont want to enter the IP address in the command. How do I go about doing that? Any ideas?
