In an access-rule, is there a way to define a host by using its FQDN, without the IOS resolving the name to an IP address? My problem is that I'm trying to give my home PC secure access to my router's SDM, but my ISP changes my IP address every few days. I have DDNS service from no-ip.com, so I have a valid FQDN that never changes. Is this possible? I have a Cisco 2811 with IOS version 12.4(3g). Any help or advise will be appreciated.
