D-Link DIR-825 :: Pinging Local Computers On Network Brings Back A Foreign Ip Address

May 23, 2012

when I ping another workstation on my local network I should get back it's local IP but instead I am getting an ip address that resolves to somewhere in Germany!  In fact if I ping any bogus name, I mean anything, it returns this same address  If I shut down my cable modem then everything resolves correctly.  And yes I have DNS relay enabled because it seems to be the only way to get the workstations to resolve external sites correctly.

Cisco WAN :: 887VA ADSL - Service Policy Brings Down Link?

Aug 7, 2012

Have installed an 887VA on the end of a ADSL connection. The provider has specified EF 150 on the link. The router is configured using a Virtual Template.
If the Virtual Template has a service policy applied, we don't have connectivity to their main site - although the CD and PPP lights are lit. As soon as the service policy is removed, we have connectivity.
We've had three sites with the same problem. Two of the sites don't have QoS specified on the link but had the same problem if the service policy was applied.

Pinging Local Router But Receive Direct Reply From ISP?

Oct 3, 2012

Lost Internet connectivity at home. connected via dsl line to my isp.when i issued ipconfig /all command i noticed that default gateway IP addr was a global ip addr. (77.36.x.x) instead of the usual private address DHCP server had IP address 58.206.x.x when i issued ping command, i got this output: "reply from 77.36.x.x: destination host unreachable" i couldn't access my router's configuration menu by typing in web browser's address field.it's very interesting, because i had network issues before but could access my router's config menu and ping it. but now, i cannot reach my local router but receive reply from ISP's router.

Linksys Wireless Router :: E2500 Can't See Other Computers On Local Network

May 1, 2012

I have a E2500 connected to a cable modem as the base of my home network. Hard wire connected to the E2500 is an linksys 8 port hub and a couple of computers. The 8 port hub is connected to a couple of computers and a xbox. I have the hub as a distro point to cut down on wiring. Wirelessly connected to the E2500 are a variety of laptops, netbooks, ipods, an ipad, a playbook, an iphone, a android phone, a wireless printer and a Ps3. Most of the devices are just using the wifi for internet access. Most devices have been setup with their own ip addresses to avoid ip conflicts. The computers and laptops/netbooks are running either Windows XP, Windows 7 or Mepis Linux. Up until now everything was going as good as can be expected, all the computers could see each other and most could transfer files between each other except when Windows gets picky.In the last few days no computers can see each other. Windows or Linux.Everything can accsess the internet and wirelessly print still just can't see each other. I reset the E2500. I updated the firmware on the E2500. I installed the Cisco Connect software (just in case I was too stupid too setup a router). Still nothing. I can ping other machines from a command prompt in windows or a terminal in Linux and get a good ping back. In the router setup via a browser I can go to the status page and see other devices on the local network but most are just ipods, ipad, playbook and the wireless printer, If I go to the administration page / diagnostics I can ping other computers and get a good answer. I just can see them from each other. I think I've rebooted every thing at least once. Yes the workgroup names are all the same (workgroup) and yes file sharing is turned on on all computers.

D-Link DIR-655 :: Need To Block Certain IP Address To Be Accessed By All Computers

Dec 3, 2011

Bought DIR-655 from Amazon. Rev. B. Come with 2.00NA firmware. Updated to latest one, and there are a lot of problems, to most of them, I was not able find any solution. Here they start:

1. WIFI SPEED PROBLEMS.No matter what speed, parameters, channel, mode, etc I select, router keeps working on 20mhz channel width. So I never get speeds above 65 mbit. In absolutely same conditions, my DIR-300 B1 (with DD-WRT firmware) gives me stable 150mbit. SO I KINDLY ASK, MAYBE THERE IS A WAY TO FORCE "40 MHZ ONLY" OPTION?

2. PASSWORD PROBLEMS.Router came with no admin password, I enter new password, hit "update" it says - wait 20 sec, after that, login page is displayed, but, new pasword does not works! since it asks again for empty password!

3. FILTERING PROBLEMS.I need to block certain IP address to be accesed by all my computers. Say this is . So I added inbound filter rule, to block access to that IP. It does not works - IP is still accesible.

4. MORE FILTERING PROBLEMS.Since above mentioned method does not works, I have to use "ACCESS CONTROL" feature. It does works, but it causes another problem, with access control enabled, all webpages with form submit stop to work. For example, if I'll have that feature enabled, when I press "post" on this webpage, it instantly will go to "this page cannot be displayed".

I bought this router solely for one purpose - I was happy with speed of my DIR-300, but I needed gigabit for my computers. So I thought, instead of buying separate switch, I'd better buy a router with gigabit. I was suggested to get TP-LINK 1043, since it's quite popular, alternate firmwares available and so on, but I refused to buy it, since I thought that some chinese company does not worth my attention. So I bought this D-Link (for almost 2x price of TP-Link) and having huge problems as you can see.

D-Link DIR-655 :: Refusing Local Connections - No External IP Address

Aug 22, 2011

I couldn't find a section for the 651.

Alright so I have an SSH server running on my network. I can successfully connect to it from a local computer using the server's internal IP address, AND I can connect to it from a remote computer using the server's external IP address (it's properly port forwarded).

However, when I try to connect to the server from a local computer using it's external IP address, I get a connection refused error. Is there something I'm missing?

Cisco AAA/Identity/Nac :: ACS 5.1 Using Local Users As Fall Back For AD

Aug 24, 2011

I have ACS 5.1 configured to authenticate users based on Active Directory. I have configured wired 802.1x too, with machine authentication enabled on ACS.When I login with credentials that exist in AD, it works fine. Then I configured Windows Authentication to ask for credentials (popup window). But I experience network disconnection when I login with a local account even though I entered correct AD credentials.I want to do the following: for an account that exist on the machine being authenticated (non-AD account), ACS should check its local database and reply with authentication success if it finds it, so the user is granted network connectivity.I heard about Identity Sequence in ACS. But I still don't see the right configuration,

Cisco WAN :: ASA 5510 - Allow Local Network To Access Public Internet Address On DMZ

Mar 14, 2013

I have a Cisco ASA 5510 I am using ASDM 6.1
I have a LAN and a DMZ and an internet connection. I am using one of the internet connection IPs to host a HTTP service on a server in my DMZ.  (its the same interface as my internet connenction but a different IP to the one used for internet connectivity)
so say my LAN is 192.168.1.x
and my DMZ is 172.168.1.x

I can access DMZ from Lan and vice versa. when i try to access the public IP (or URL) from a pc in my LAN i get nothing.
I have enabled DNS rewrite (doctoring) but it is still not working. the HTTP service is available from other sites.

D-Link DIR-655 :: Computers Cannot See Each Other On Network

Mar 7, 2011

Am about to set up my new DIR-655. I noticed that the routers default IP is  The router it replaces used I have several devises on the network with fixed IPs 192.168.1.x (printer and Stora) and since I do not want to change them, can I leave them as is?Also, last time I changed the IPs that the router hands out, many computer could no longer see each other on the network, due to firewall issues. So, can I set the router to use a range like 192.168.1.xx even though the routers address is not changed? orshould I just change the router IP to and change the range. Also do I need to change the mask if I do any of this?

D-Link DIR-615 :: Utility To Show Which Computers / MAC Addresses Are On Network?

I don't know if they were to clone their MAC address as to whether this would show up with the cloned address in active sessions list. How I can stop some users from getting through at certain times? Any utility I can use on my Mac (Mac OS X 10.6. to show which computers/MAC addresses are on the network?

Can't Access Other Computers On Windows 7 Network With Vonage And D-Link Router

Feb 25, 2011

I have 2 Windows 7 desktops that are both connected to seperate vonage boxes and those vonage boxes are connected to my D-Link DIR-655 router. That D-Link router is getting its connection from a Comcast router. I am looking to get one of the desktops to share a printer from the other one which has it hard wired via USB cable. When I first set this up I did not have the vonage boxes and the desktops were connected right into the router and everything worked fine. Now that the vonage boxes are in place it is a mess. I can get internet fine on both machines, but no file/printer sharing. I have followed all the steps to setup the correct workgroup and file and printer sharing options on both windows 7 machines but they cannot see each other at all. My feeling is that now that the vonage boxes are there that instead of the desktops looking at the D-Link router for its sharing option they are looking at the vonage boxes and that is why they cant be seen. Does this make sense? Is there a firewall on the vonage boxes stopping these two desktops from seeing each other? Do I have to change something on the D-Link router options for it to give access to the vonage boxes for these 2 machines to see each other for printer/file sharing?

D-Link DAP-1522 :: Devices Local Do Not Show On Network Map

May 17, 2011

This is the configuration I am running:Internet > Cable Modem > Netgear WNDR3700 Router ~~ DAP-1522 > Wired Windows 7 PC + Linux PC + Printer.The Windows 7 and Linus PC's do communicate well to the internet as do any laptops accessing the router wirelessly and any devices wired to the router. That is the good news.

The bad news is that any devices located after the DAP-1522, including the DAP-1522 do not show up on the network map of either the router or any of the wireless laptops. Neither does the Win 7 PC connected through the DAP-1522 show any networked devices, whether through the DAP-1522 or not, even though network discovery is turned on.

Right now the DAP-1522 is set up to function as a bridge and is in "Static IP" mode. I tried changing it to DHCP, but the DAP-1522 will not allow saving that setting, even though it will allow changing it. It just reverts back to "Static IP". The firmware version is 1.31, and the firmware update went well after a workable logon to the admin page was discovered. Also the one-button (WPS) set-up to the router worked as far as allowing an internet connection.

What needs to change to allow all the devices to show up on the network maps and maintain internet access? Ultimately, I would like to stabilize the IP's of the major components of the network to make troubleshooting easier. But to do that the devices need to show up on the network maps, particularly of the router, so they can be added to the IP reservation table by selection.

D-Link DIR-655 :: Can't See Hard-Wired Printer On Local Network

Dec 18, 2010

I recently purchased a DIR-655 and everything's working fine -- Internet access, visibility of local shares, etc. -- with the one except accessing to my printer (Brother MFC-7440N) that's hard-wired to a port on the router.After installing the latest PC SharePort Utility on my two Windows 7 desktops, they're both able to connect and use all of the features of the printer (print, scan, etc.). However, I can't say the same for my two Macbook Pro's connected via WiFi (802.11N).  I installed the latest Mac SharePort Utility on both, but neither can "see" the printer.  Caveat:  If I connect the laptops via a LAN cable (ie. hard-wired directly into the router), they're able to see the printer.  how to configure the router (or Mac) to allow them to see the printer?

Cisco VPN :: 1921 Loop Back Interface / Static IP Address For Client

1)  Is it possible to assign same ip address to the same client each time  it authenticated, preferably without using DHCP? Im definely sure that  it possible but cant find corresponded configuration examples (my device  is Cisco 1921 with IOS 15.0.1).
2)  Is it possible to assign dynamic crypto map to loopback interface (the  purpose to make EASY VPN Server accessible through two interfaces -  maybe you recommend other approach instead?) - as i move workingcrypto  map from phy int to loopback - i cant connect with reason "Phace1 SA  policy proposal not accepted"
