Customers unable to browse the internet on the router from Cisco 871 K9

Hello world

"I just bought my Version of K9 Cisco router 871 running this flash system image: c870-advsecurityk9 - mz.124 - 4.T8.bin".

I am trying to configure this router for home use, while I can block a part of Web traffic (porn sites, sites of films because of the children), but I realized that I was unable to apply the access list Match-class version url (http host).

My major problem is still the base of the router config. WAN has a DHCP IP assignment with the 192.168.1.0 network

The Lan is supposed to have 192.168.3.0 network. IP addresses seem to be properly attributed but not able to ping on the internet router. Local client also cannot resolve DNS. Here is my cofig file.

Please help.

Hello

problem is that you have changed the IP address of the interface VLAN 1 from 192.168.1.254 to 192.168.1.1
If you need to change by default-router dhcp pool:
Select conf t
Richard-Edet dhcp IP pool
no default router
default router 192.168.1.1
end

NAT is also missing:
Enable
conf t
IP access-list standard NAT
permit 192.168.1.0 0.0.0.255
output
IP nat inside source list NAT interface SA4 overload
end

Also perhaps you cannot ping the router console PC because the computer's firewall blocks the ICMP protocol. In windows, I'm sure he is blocked by the firewall. Then you can try ping 192.168.1.1 from the PC and it should work.

Try above changes and then write me if it works, or so we can make other changes.
You can also post the output of the commands (if this will not work):
router: ip road show
router: ping 8.8.8.8 (it should work if your internet provider doesn´t blocks the ICMP protocol)
PC: ipconfig/all

    Hello @[email protected] / * /;
    Thank you for your message. I had a glance on the configuration for you. You used a network as opposed to a wild card mask in your access control list for your NAT statement. This changed the field from the source to 0.0.0.0 automatically, which is going to be does not match your interior traffic and NAT'ing outside.
    To fix this, please run the following commands and test once more.
    no access-list 101access-list 101 permit ip 192.168.1.0 0.0.0.255 any

  • Booklet 70CT: unable to browse the network

    I'm trying to connect my booklet 70CT to an existing LAN. I use a Fast Ethernet Linksys PC card in the booklet, connect a Linksys Wireless-G Broadband Router on a LAN port.

    There are two other computers connected to the router network OK. I did all the installation procedures in the manual of the PC card and everything seemed to be working normally.

    When I double click on network neighborhood on the booklet, I get a screen with "Entire network" in this topic. When I double-click it, I have a sign saying "Unable to browse the network."

    Hello

    I searched on the Microsoft Web site to some proposals of solution and found this:

    http://support.Microsoft.com/kb/260214

    This problem may occur if there is a key to logon automatically in the registry at the following location:

    Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.

    General precautions for Outlook Express:
     
    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

  • "Unable to install the plugin from RoboHelp for FrameMaker...." »

    Hi-

    I have 9 Frame and a copy of RoboHelp 8.0.0.203 demonstration and works in Windows 7 (all of a sudden. Yet to learn my way in the operating system after a catastrophic failure of the weekend with my trusty little machine XP.) I have no TCS2; just these two stand-alone tools. I have a book of frame I need to turn into contextual HLO and am auditioning Robo for the task.

    No dice. Whenever I try to import (see below re linking) I get an error message in a box marked "RHUtils": "unable to install the plugin from RoboHelp for FrameMaker. If please close FrameMaker and try again. »


    With your permission, I'll cover a few points in the order in which they come to mind:

    == > Initially I tried linking, hoping of course to the advantages of the single-sourcing. I learned in this forum and elsewhere (-btw, thanks for this great resource) I need the TCS2 in good faith in place to connect. Thought that I could import for now instead of it, just to see how it happened; received the same error message.

    == > It was AFTER I had done the research and on the Adobe site (http://www.adobe.com/support/robohelp/misc.html) found this: "the plug-in for RoboHelp, FrameMaker FrameMaker users allows quickly convert any number of books for a simple import or FrameMaker files in RoboHelp 2002 and X 3.» RoboHelp X 4 includes the plug-in! For RoboHelp, FrameMaker plug-in is only available for Windows. To install the plug-in, unzip the RoboMIF.dll into the Plugins folder in the installation of FrameMaker folder (normally found in C:\Program Files\Adobe\FrameMaker7.0\fminit\Plugins)...   Once the plug-in has been installed, restart FrameMaker. FrameMaker now includes a RoboHelp menu. "OK: I have downloaded RoboMIF.dll, installed according to the instructions, rebooted just in case, and now"Adobe RoboHelp"actually appears in the menu bar in the frame. I however always the error message whenever I try to import (now).


    == > For several of these attempts Frame was indeed closed. For several other Frame opened to the entry page and nothing else. No apparent effect, anyway.


    == > Import and link Word files seems to work very well - which is cool, but my document is in frame at the moment. I know I can convert, but up to now to convert the word seems to need to get all references, what I did in the framework. Doable but not my first choice.


    == > I found a thread of editors at http://www.mail-archive.com/[email protected]/msg18576.html / / www.mail-archive.com/[email protected] msg18576.html relating to this problem. The recommendation, (published here for brevity), who was the author:

    1. locate [the] Maker.ini file and ideally make a backup of it, just in case.
    2. in the [APIClients] section of the maker.ini file, add the following line:

    RH4FMver9 = Standard, RH4FMver9, C:\Program Files\Adobe\Adobe Technical Communication Suite 2\Adobe RoboHelp 8\RoboHTML\RHFrameMakerServer9.dll,all

    3. you should now be able to launch RoboHelp and 'link' files, FrameMaker, FrameMaker application should launch correctly.

    This doesn't seem to be my answer because I don't yet own TCS2. This path does not exist.

    (I still get excellent advice of training provided by this answering machine, RJ Raquez, to http://blogs.adobe.com/rjacquez/2009/05/linking_framemaker_9_books_in.html.)

    In any case, this is where I realized that I was, at least for now, of ideas. Does anyone have more?

    Thank you-

    Anne

    If you do not want to go down the road of miftogo mentions Arnis, you can always download the demo of TCS2 - it is fully functional for the period of the demo. I am tempted to install it in its own virtual machine (or another machine entirely) so that you do not get the demo interfere with your legitimate copy of FM9.

    We have improved our ASA 5505 to 8.3 firmware image (2) and we have a working VPN configuration (customer VPN in Windows can connect and browse the network of the company as well as their local networks [split tunnel seems to work in this regard]).  However, some time connected they are unable to also browse the internet.  In our configuration of 8.2 (1) we have done 'something' to allow remote users to browse the internet at the same time, but apparently this is not transferred in the upgrade.

    I'm sure it's a simple nat our order routing, but it can't know.  I've gotta hit the road now but will post our config this afternoon if no one knows the "secret" to do.  Ideally, internet traffic to remote users out of their internet connection and not be achieved through the office.  We understand the risks associated with it.

    Hi Scott,.

    To the best of my knowledge, I don't think that l2tp over IPSec supports split tunneling. If you use the Cisco VPN client, you should be able to get this working.

    What we can do in this case is to set up turn on the SAA for these vpn clients. Please add the commands to run below:

    permit same-security-traffic intra-interface

    network of the NETWORK_OBJ_10.0.0.0_27 object

    dynamic NAT interface (outdoors, outdoor)

    Let me know if it helps!

    See you soon,.

    After I installed, I noticed that a lot of missing drivers so I scoured internet and downloaded most of them. The problem I have is that the ethernet connection seems to not work properly. I installed the driver on the toshiba site and hooked it up to a test network to my polytec.

    On this network to test an internet connection is available, but the laptop cannot browse the internet! I can ping other PC networking on mobile Internet sites and ping but cannot browse their IE. Other network PC cannot ping the laptop automatically obtained IP address.

    Any ideas what's happening?

    Hello!

    Have you tried another browser like Firefox? I don t use IE because Firefox is much faster and I can't get a large number of modules.

    In addition, you should try to disable the firewall on the laptop. Maybe it s blocks the internet connection or the internet browser.

    Last but not least try to use a static IP address. You can change this in the TCP/IP settings.
