Configuring a Router

How can I configure a Cisco Modular Access Router 1721 with a WIC. WIC will be used for connection to ISP. Int0(Ethernet) connection will be to my LAN


Re: Configuring a Router

Ahhh yes... the good ole 1721. Great router no doubt. If you are not comfortable with IOS command line entry, then I would use Security Device Manager. You can download from Cisco free of charge and it work great!!

I would recommend not installing this on the router but on your client PC and then connecting to the router. First thing first, put a IP address on your Ethernet interface that matches your IP on your PC that will host SDM. For example:


router#conf t

router(conf t)#int eth0

router(config-int)ip address


Now get the router ready for SDM with the following commands:

Config the server:

Router(config)# ip http server

Router(config)# ip http secure-server

Router(config)# ip http authentication local

Give yourself access or this will be a quick exercise in password recovery...

Router(config)# username privilege 15 password 0

Better turn on and config Telnet also, since we are here:

Router(config)# line vty 0 4

Router(config-line)# privilege level 15

Router(config-line)# login local

Router(config-line)# transport input telnet

Router(config-line)# exit

Now lets save it and roll on with SDM:

router#wr mem (or copy run start)

Now launch SDM and just follow the config guides and you are ready to connect to the World. The first website I would check out (just to test it of course) would be:
