Line-rate issue with cisco 878

Hi
We are having an issue with Cisco 878 4-wire configuration. It is kind of randon that some of the service are unable to sync. up at line rate of 4608 and since we can't sent the line-rate to Auto we have no opther option tghan hard coding the line speed on the DSL controller 0 which seems to me a lot inefficient. Could anyone help me solve this. I am including the DSL controller 0 config

controller DSL 0
mode atm
line-term cpe
line-mode 4-wire enhanced
dsl-mode shdsl symmetric annex B
line-rate 4608

    Why can't you set the line-rate to auto? It's always worked for me, and unless you don't want it to connect as fast as it can, you'll be limited by whatever you predefine.

Just a suggestion, there are free modem firmware updates from cisco's FTP site to most 800 series routers. The firmware also get updated with a major IOS release, have you tried?
just download the correct one, instructions are on the site to download. Basicaly you rename the file and save it onto your flash. the check with "sh dsl int" in enable mode, it will list the FW as "external" source. When renamed or deleted, you are back to the original.

hope that will help.

All configuration can be done with the router GUI.
Firewalls: Server Side Having a server side firewall is the typical configuration on many systems. There is only one method for doing this, whether you use telnet or ssh: map a port to be forwarded to the server in the firewall router. It is not advised that you use telnet from the Internet for security reasons; that is usually why you have a firewall.Decide which method of connectivity will be allowed, and determine what port you will use to forward to this service. If there is only one server involved, you can use port 22 for ssh or 23 for telnet and forward them straight through to the server. But if there are several servers involved and they do not have public IP addresses, you will need to pick different ports on the firewall router and let the router forward those ports to the different internal servers.

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.

Connected straight through ethernet cables on async connections of Cisco 2516 terminal server, but unable to connect to any device.


Assuming you have the wiring correct, you will have to configure the 2516 to do what you want. Without more detail, we really can't provide any more help.

Is a cisco 878 working normally in a isdn dsl line with splitter?


no. 878 is for SHDSL.
837 = ADSL
Most older routers (like a 2503) will have a BRI interface for running ISDN.

Router cannot get IP with cisco 675 modem


Hi,

The issue may be due to the existence of two (2) DHCP servers; 1 in the Cisco 675 and the 2nd in the DLink DI-524. You need to disable the Cisco's DHCP server function and assign static IP add & config to the DLink WAN config. This way it will only be the DLink handing out IP adds to the network.

The workaround. Install your original configuration/setting without the DLink DI-524 - PC direct to the Cisco 675 (I am assuming through Ethernet ports). Verify that indeed you are connected to the Internet and can surf the net, check e-mails, etc. Check your Networking Connection Status. Log down your PC's IP Add, Subnet Mask, Default Gateway, DNS. For purposes of discussion, let's call this "N1".

After your Internet connection has been verified with your PC directly connected to the Cisco, remove the direct connection and connect the DLink DI-524 in between the Cisco router and your PC.

Log in to the DLink and modify WAN parameters using the "N1" configurations/settings.

It might be of help to disable any security (WEP WPA, MAC etc) at least while configuring.

Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
