Hello, I have four 2521 routers and three 2954 switches. I connected my ISPs modem from the ethernet port and plugged it into port 24 of one of my switches. I also configured the switch for VTY access and gave it a login password. I would like to log into the switch to configure it and telnet into all the other devices from a remote location. But I am unable to ping the public address assigned to me by my ISP. So I can't even telnet to the switch. Help
