This tutorial will walk you through configuring a Cisco Router to server as a DHCP server for client computers. Commands: R1>enable R1#conf t R1(config)#service dhcp                                     >   Enables DHCP R1(config)#ip dhcp pool mydhcp                ...

Also, you cannot enter privileged mode (which is the IOS EXEC mode that allows you to view or change the configuration on a router) from Telnet unless an Enable password is set. These are very basic features of Cisco routers and allow only some security. Screenshots I just typed “ping 192.168.118.66”, Router R1 IP address:
