Cisco 1841 is a highly capable router that provides the full feature set needed for small or remote office connectivity to the Internet or other private networks. Dynamic Host Configuration Protocol (DHCP) service is one of the features supported by the cisco 1841 router port and must be enabled if the router is expected to provide dynamic Internet Protocol (IP) addressing to hosts on the private network. The DHCP feature includes many options; however, you can set up a standard configuration in about 30 minutes.
