Hi!
You can access the user manual for your router by going to:  http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/857sg_bk.pdf

But simply put,  - You have to enable the web interface in Hyperterminal/Telnet/Terminal - To connect to your router this way, open your Terminal and type the following commands in order:
1) enable (enter password if necc.) 2.) config term 3.) ip http server (this command might also be set to "no ip http server") 4.) exit
After doing the above: 1.) Press Cntrl+Z 2.) Go to Copy, Run, Start 3.) Open your browser and go to "10.10.10.1"
Good luck! -TJ

There are 2 models of the Cisco 857 router. You must have the the Cisco 857W in order to support 802.11b/g wireless. The 857 without the "W" will not support it.

I would like to configure port fowarding on the Cisco 857 router using the http interface rather than via any coding. Is it possible and what do I need to do? In my scenario, the router must be configured...


It is possible to configure your router via a web browser. Although it’s disabled by default, your router has its own mini HTTP server built in. This provides another way to gain access to the router for the purpose of issuing commands. To enable the HTTP server, you have to use the command "ip http server" from the global configuration mode.

cisco(config)#ip http server
cisco(config)#

Then open a web browser and point it to one of your router’s IP addresses. The interface is not really nice, but you can issue commands using hyperlinks.
For security reasons I still suggest that you keep the HTTP server turned off, since it offers just another point of access for potential hacking.

What is so bad about the command line? Configuring port forwarding is actually pretty easy, once you know the commands.

Type show ip interface to find the name of the interface you want to set port forwarding for.

The show ip nat translations command shows you the current port forwards on Router.

Type configure to enter the configuration mode
The command for port forwarding is: ip nat inside source static (TCPorUDP) (YourComputersIP) (PortToForward) interface (name)(PortToForward)

in you case:
ip nat inside source static tcp 192.168.0.1 5900 interface (name) 5900
and
ip nat inside source static tcp 192.168.0.2 5901 interface (name) 5901
replace (name) with the interface name you got from the first command.

Then press CTRL-Z to end the Configure Session
Type copy run start once you tested your settings and press ENTER for the question Destination filename [startup-config]?

I have heard of some commercial tools that let you configure your router via web interface, but they are very expensive (around 1400$).
You can try it out for 14 days. Go here.
If you want to play with a free one, go to Cisco (link) and check it out. (You have to be a member though.)


If you have any more questions, just come back here and leave a comment - I'm happy to help.

You might need to reset the password. In order to do this, follow these directions:

  1. Console into the router, then power cycle it. As its rebooting hit the "break | pause" button on your keyboard, and you get to the rommon1> prompt.
  2. Then type rommon1>confreg 2142 rommon2>reset
  3. The router comes back on as if it were new---answer no to the first question, and sometimes it asks a second question (do you want to terminate autoinstall, or something...)---answer yes to the secondquestion if it asks. Then hit enter and you get router> in a few seconds.
  4. Then router>en router#copy start run

create a new account:
  1. router#conf t
  2. router(config)#username bob priv 15 password bob
set register back:
  1. router(config)#confreg 0x2102
  2. router(config)#exit
  3. router#wr
  4. router#reboot

and that should let you login with bob/bob

Router configuration


What's the model number and brand of that router. It's odd if it doesn't have a default IP address. Most routers have default IP. I guess its a Cisco router? If its a Cisco router, it requires a technical person who knows how to configure a Cisco router. Or I'm thinking that it's an Access Point.
