Cisco WAN :: T1 1700 Cannot Ping From Sites

Dec 19, 2010

I have two sites with a dedicated, point to point, LAN, site 1 has a Cisco 1700, LAN IP:; Site 2 has a Cisco 1800, LAN IP: site 2 I can ping the router on the other side:, but nothing else on that network
From Site 1 I can't ping the other network at all,Both sites ping fine to their respective local interfaces. I also noticed, when trying to ping site 2 from 1, the  "WIC ACT/CH" light blinks, otherwise it's off.
Site 1 has it's own web connection through COMCAST, site 2 is set to route through site's 1 connection to go out. The only thing the routers are doing are the actual connection between sites, and in the case of site 2, routing web traffic to, which is a Sonicwall on Site 1.
This was all working just fine, for a long time, up until yesterday, when the problem I described started happening.

Cisco Switching/Routing :: 1700 ADSL Router - Connecting 2 Sites Together

Jan 23, 2012

We currently have a main network running through a static broadband connecting using a Cisco 1700 ADSL router, everything is working fine locally.

We are looking to rent some space in an office nearby so im going to order another business adsl connection with static IP for this site and i currently have a spare 1800 router.My question is can the cisco routers connect up like a VPN connection so both sites work together and will the connection remain online constantly so from the remote office we can access all our servers from the main network?

Also how does the IP addressing work on 2 sites. The main network uses 10.120.21.x and DHCP is assigned from a cisco router. Does the remote network assign from the same DHCP server or would the remote sites cisco router need to be setup to give out DHCP to local machines. If so what would be the best IP setup to use.

Has IP - Cannot Ping / Connect To Sites

Feb 17, 2013

I have a laptop that works perfectly fine when plugged into a network cable, but the wifi refuses to work. It pulls an ip, and everything looks good when I run ipconfig/all, but it can't even ping the router. All other computers on the network are working fine. I've flushed dns, set static IP and DNS, uninstalled/reinstall device, updated drivers, bios, and firmware, and even created a backup image of the computer and reloaded the os using the recovery partition. The event log doesn't tell me anything, and there are no flags in the device manager. I'm at a complete and total loss. I cannot figure this one out.The laptop is a Compaq Presario CQ50-142US. Vista 32bit OS. Everything was working perfectly fine before it got a virus. I ran through the standard procedures of AVG, Malwarebytes, TDSSKiller, and even resorted to Combofix, but somewhere along the line the wifi dropped off and will not come back.I even double checked the HOSTS file and IE proxy settings to ensure I wasn't crazy; although I know those should've affected the wired connect too.My last step is to either replace the wifi chip (which I don't think is the problem), or wipe it and load the os from scratch, but I don't have an oem disc since it has the recovery partition.

IE / Firefox Not Connecting But Can Ping Sites

Jul 14, 2011

I have a Windows7 laptop that was working fine til yesterday.I switched it on at home last night and it picked up my wireless connection but when I opened IE or Firefox it would not access any webpage (blank screen, no address that its resolving on status bar at the bottom and just a progress bar (IE) or a 'searching' icon (firefox)The network connection page in control panel says that it is connected and I can ping sites from the command prompt and some other software such as skype seems to be connecting.I have disable both bullguard firewall and made sure the windows firewall is off.I have come into work this morning and am getting the same problems, even when connected by ethernet cable, I can also see other computers on the network.I was occasionally getting a dial up connection pop up box appearing from an old dial-up connection I had set up, but have now deleted this connection.

10 To 90 Percent Of Internet Connectivity Down - Cannot Ping Sites?

Sep 12, 2011

I have ATT DSL and pretty much every night, I lose a large portion of the Internet. I cannot ping these sites, while the rest of the net works fine. The other night, I could not ping major domains like ATT, CNN, MSNBC, BBC (a chronic missing domain). On the other hand, I could get Yahoo fine and go to a streaming audio site and run music perfectly...but about 90% of the Internet was unreachable. Could not load their sites nor ping them in command line. The other 10% worked flawlessly.

Cisco Wireless :: 3602 AP Unable To Ping Anything At Branch And Central Sites

Mar 7, 2012

We are in the process of evaluating Cisco wireless controllers and AP. We have 3602 APs and 2504 controllers right now. We have multiple branch offices connected to the main office through layer 3 and they all have different vtp domains and vlans. I am trying to deploy APs at the branch offices and connect them back to the controller and the central site. I created a sub interface and ssid with one of the vlans at the branch office on the controller and was able to get the AP to join the controller through DNS. However, a client at the branch office connected to the AP was unable to ping anything at the branch and central sites. Any documentations on how to deploy such a setup where the controller is at the central site and AP at the branch office going through multiple routers in between?

Cisco VPN :: 1700 / Route Traffic Over VPN Tunnel Like In GRE?

Jun 15, 2012

I'm station overseas and it's really hard to access certain websites and servie like Netflix or ESPN. What I had created was GRE tunnel from my Home "A" to my current location "B" and route my traffic from point A to B using 2 cisco 1700 routers ( and It was working great) but now I can't use GRE nomore. I still have PIX and ASA on both sides and I was trying to do that over VPN tunnel but I can't ping VPN tunnel gateway( basicly what was next hoop in GRE) on the other end ( which is the main problem why I can't route traffic to remote site). I was wondering if I can still do the same thing over VPN tunnel that I did with GRE tunnel.

Cisco WAN :: 1700 Unable To Reach Remote Router

Apr 3, 2011

We are facing strange issue in our network. We have a remote branch which is connected to main branch using Leased Line. Remote branch is having Cisco 1700 Router. Every day in the morning time the remote router is unreachable. We are not able to reach (ping/telnet) the remote Router but able to reach L3 switch/ LAN behind this router. The users from remote branch is also not able to reach the local router but they are able to ping the Main branch.Users in the remote branch are not able to access any resources in the main branch during the issue.
During the issue, we have checked the remote branch router and found the CPU utilization of the Cisco 1700 router is very high (99%). If we run "Show process CPU" command (please find the attachment) specially IP input process is very high (97%).

Cisco WAN :: 1700 - Route RDP Port Based Traffic To WAN Interface

Jun 11, 2013

this is my first time configuring a cisco router. For instance, a cisco router 1700 with 2 ethernet WICs and 1 LAN port. We have 2 ISPs one more stable than the other. We use an RDP session to an external host identified by lets say IP address using ISP2 to get to this computer.   We use ISP1 for all the internet usage, web pages, youtube etc.  We are thinking of using this cisco router 1700 to make the packet filtering and routing of this RDP session to the correct ISP2 since we only have 1 NIC per computer on the LAN side.
The main idea would be:
                                                       | YES -----> ----------- then use  ISP2
LAN--------->  Are the packets RDP ?
                                                       | No-------->  ----------- then use ISP1
Does this can be achieved using packet filtering using extended ACLs and to be router from the lan interface to route rdp (port 3389) packets to ISP2 WAN interface?

Cisco WAN :: PPTP Client From 1700 Router To Microsoft VPN Server

Aug 25, 2012

I'm trying to configure 1700 K9 router to act as PPTP client and connect to Microsoft VPN server (in order to enable all clients on LAN to seamlessly access host on remote location). [URL]
I'm using GMS3 to test everything in lab environment. I managed to connect to Microsoft VPN server but the connection drops immediately. Below is debug info from router R1 (router R2 just simulates host on LAN) and configurations for both routers. The only clue I got from debug is that immediately before closing connection there's a message "CCP: Failed to negotiate with peer"...
R1#sh debug
PPP detailed event debugging is on
MPPE Packet Details debugging is on

Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface

Mar 31, 2012

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

Cisco Switching/Routing :: Can Ping From R1 To R3 SVI4 Gateway But Cannot Ping Host

Dec 12, 2011

I set this up and I can ping all the gateways but never the hosts.  I was hoping I could make these links between 6500's a mix of L2 and L3.  Check it out.  They are connected in a linear fashion R1--->R2--->R3.  I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4.  I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration.  I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

Cisco WAN :: 1700 Series Router To 2811 Series Router / Going From T1 To Ethernet?

Jan 17, 2011

I  have not done much with business routers, but we have a 1700 series  with a WAN WIC-1ENET card with a RJ45 connection. We had a T1 line and  will be moving to ehternet. We are going to be moving to a 20MB line,  and i just wanted to make sure I have the right connections before  installing. We also have a T1 line in another loaton and would be moving to this same 2811 router there as well.We  would also like to copy over the configuration from 1700 series router  to the 2811 router. Would it be easier to do it by hyper-terminal? Also if we keep the 1700 routers are they capable of using layer-3?

Can't Ping XBox 360 But Can Ping Other Devices

Mar 1, 2013

I had both a Westell 7500 and a Linksys Router working fine and had my 360 setup as an extender for Windows Media Center so I could stream TV, Music, Movies, etc from my desktop to the 360. Then I switched my modem/router out with a Zyxel PH5001Z

So now today I noticed that I can no longer find my desktop through the XBox. I have adjusted my firewall settings on the modem itself, even completely disabling it. UPnP is enabled for the 360 and the device is showing under my device table. At first I wasn't able to ping any network devices but after creating an ICMPv4 Firewall rule it worked fine. I've confirmed the XBox IP Address through Network Map, the Device Table on the modem and through Network Settings on the XBox. I've diabled my modem firewall as well as Windows Firewall, completely and I still can't ping my XBox or set it up as an Extender.

I have the XBox connected wirelessly using WPA2-Personal and it's operating in 802.11g/n mode.
