Cannot get SW1 to the second network of ping and can't get the HQ router to ping SW1.

Hello the forum community.  I am new to Cisco Configuration and cannot understand why, in the attached packet tracer file, I can't have my SW! switch to ping to the gi0/1 interface of the branch office router and beyond.  I also can't understand why I can ping to the gi0/0 interface on the router in the branch office router HQ, but cannot ping the switch SW1 and beyond.

Ideally, I'm trying to configure the network so that PC1 can ping 172.16.1.100, which is a loopback on router HQ.  I ping the closure of the branch office router, but not the switch SW1.  I cannot ping the gi0/1 interface on the router of the branch of the SW1 switch and do not understand why.  I can also ping the gi0/0 interface on the router in the branch office router HQ, but cannot ping the switch SW1 of the HQ router.

PC1 - 10.1.1.100 255.255.255.0

SW1 - VLAN 1 - 10.1.1.11

Branch gi0/0 - 10.1.1.1 255.255.255.0, gi0/1 - dhcp assigned as 209.165.201.1 255.255.255.224, dynamic NAT activated with access-list 1 (permit 10.1.1.0 0.0.0.255), the pool name is NAT_POOL with the address range of 209.165.201.5 - 10 255.255.255.224 as NAT address range.  I can see it working with debug ip nat active when I ping the router address 10.1.1.1 HQ, although I have test the ping without NAT and it is always successful.  Gi0/0 inside the nat, g0/1 outside the NAT.

HQ gi0/0 - 209.165.201.2 255.255.255.224, dhcp server enabled to provide an address for the router in branch gi0/1.  I had to add a static ip route 10.1.1.0 0.0.0.255 209.165.201.1 in order to be able to get the ping to the router HQ to branch router gi0/0 to work.  Don't know if there is a better way to do it, but it's the only way I could make it work so far.

You will need to rename the .txt file, attached to. pkt.

Thanks for any help!

Hello

The switch has ip routing enabled, if so disable it and give it a default gateway instead

no ip Routing
IP default-gateway x.x.x.x

  • Cannot get 3050 again router connected a wireless

    My router DSL of ATT went out on me a few weeks ago, and they sent a replacement.  I got a dozen devices connected to the new but cannot get the 3050 a j611g connected.  I tried everything I could find...

    1 uninstalled all HP software and going through Setup again.

    2 reset the default printer network settings and repeat step 1.

    This includes, of course, passing by the "printer setup and software ' program on my computer."  Nothing works.  I found these instructions on the site of HP...

    To reconfigure your settings on a printer wireless have no control panel wireless Assistant:

    1. Insert the CD into your computer.
    2. Select reconfigure network settingson the Welcome Back screen.

    The problem is that I don't get to "Reconfigure network settings" as an option when I put the installation disc in my computer.  No 'Welcome Back' of the screen or the other.  Any help would be appreciated.

    Appreciate the help of everyone.  But it must have been a material situation. After tons of calls and a few broken promises, I finally got a case manager who took care of me and sent me another printer.  Saved my faith in HP.

  • best way to put up a second NETWORK adapter for the data on NAS Server store

    I want to add a second NETWORK card if I can get the best possible performance for when I move the data store of the ESXi host to the NAS (which will also have a dual NIC). What is the best way to set up the NETWORK card on the ESXi host to achieve?

    PS - I am aware that I am limited to the real network speed of 1 Gbps and conditions and I agree with that (any of the virtual machines are eager resources or production).

    SOLVED... I think so. JPM300 got on the right track, but I was still not clear on it so I googled all this involving and finally landed on an iSCSI with MPIO configuration. I ended up as a result of this article (I use a Synology DS415 +, but the steps are pretty universal): How to use iSCSI targets on VMware ESXi with Multipath i/o - SynologyWiki. The article is old but always worked perfectly for me. I checked the two paths/NIC are used simultaneously, but I did not actual test to see if I have 200 MB/s of bandwidth (I've seen 80 MB/s when the cloning of virtual machines to the new iSCSI data store using vmfstools).

    I ran into a problem where the second path is not added during the alternating market; I removed the path shown and then was able to add the second path, then the first path again.

    Hope this helps someone.

  • cannot get the keyboard to select windows xp when I have only four seconds to select is stuck on windows xp professional and cannot get the keyboard to use arrows to select

    cannot get the keyboard works when reebooting said cd I need driver sata when reebooting he gives four seconds to schrol up to windows xp but the line is highlighted on a windows xp profesional bellows and can't seem to choose windows xp on its own keyboard wont respond but lights from F1 or f2 f3 until f12 choose please help

    A few old machines will not recognize a USB keyboard/mouse until after Windows starts.  Look at the back of your computer and see if you have a PS/2 (round) connector for a keyboard and a mouse.  If you do, then you will need to use a keyboard with a round PS/2 connector or a USB-to-PS/2 adapter and plug the PS/2 connector on the back of your computer so that it recognizes the keyboard until Windows starts on your keyboard.

    The SATA driver applies to your hard drive.  A CD of start-up/installation of Windows XP does not recognize a SATA hard drive.  If you install Windows, you will need to hit F6 at the right time and insert a floppy with the SATA driver on this subject.

    Go to your computer manufacturer's support web site and search for the Windows XP drivers for your specific model number.

    If there are Windows XP drivers, then download to a folder on your hard drive and install them all, starting with the card mother/chipset drivers, LAN, Audio, USB, SATA, etc, and so on.

  • OfficeJet L7590 cannot get network on the extension of the network installation

    I'm hoping to find help before I need to run 50' network cable lilou my living room.

    I have an Office Jet L7590 printer.  I've had it for a few years, and until recently had it put in place thanks to our home wifi wireless.  We have 3 computers that print to it, all equipped with Windows Vista, with no problems... until I had to rearrange my office at home for an adult child go back home (don't started even get me here, lol).

    Thus, the new agreement is that the printer is now connected to the Extender of wireless network that we have implemented because I wasn't getting a good signal in the living room of the wireless router.  Since we moved the printer it reads "printer offline" in my control panel.

    The printer works fine if I plug a network cable on the router instead of the extension of the network, so I know it works, but because it is now enjoyed away from the printer that the extension of the network, I really need to connect it all together.  I'm pretty much the only computer that connects to the Extender, the others are connected via the wifi router.

    I hope that I gave all the necessary information, if anyone can help me please... I got until Tuesday evening to figure this out before I have to pass the cable network around the living room!

    We had problem connecting printers wireless Extenders because it seems that the printers have a difficult time trying to determine which SSID to connect to your router since the and extension have the same SSID... right?  One thing that works is power line adapters.  This example uses the wiring in your House for the Ethernet connections.  Works very well and since printers are not nits, no need of a lightning speed fast.

    What may also work is a client bridge.   I wrote this a while ago and will work in the House very well with a wireless printer.

  • Cannot get rid of the network

    I have a vcenter server 5.0 with 2 hosts.  When I migrated a lot of virtual machine to another group of ports in the "VM Network" group, most of them show they are now linked to the port group that I moved and the former group VM Network.  the vm network group shows as inactive and I deleted the network of the vm from the two hosts.  If I connect to the host individually this network does not appear.  In vcenter, if I go to networking, I see that VM network listed there, and it shows the VMs still plugged on.

    I'm guessing that there is something wrong with the database, and this port group is not being properly served.

    Welcome to the community,

    just a guess. None of the virtual machines have a snapshot active - at the time of his creation--stressed the port group? As long as the snapshot exists, you will see the old port group.

  • Installs the modem and the router and cannot get it to work?

    Recently, I disconnected and then reconnected my computer laptop Windows 7 and XP desktop to a Linksys router that connects to a cable modem Webstar. I did 4 or 5 times in the past with no problems.
    Two computers can connect with success directly to the modem. When it is connected through the router, they appear connected (i.e. connected to the local network) but cannot access the internet. I tried to switch, reset etc... checked the cables, without success.

    I tried a second router (Belkin Wireless G) I also used before, but get the same result. I appear connected but cannot access the internet, even if I can connect my laptop to other nearby wireless networks.

    If I try to connect from the network schematic page in Windows 7 it tries to connect using a PPPOE (no matter who is and gets a 651 error.

    I tried all the MS diagnosis/troubleshooting software available on Windows 7 but cannot id the problem.

    This should be simple, but I'm out of ideas. Any help would be greatly appreciated.

  • Will set up the HP Photosmart 7510 new iMac OSX 10.7.3; Cannot get the home screen appears.

    Instead of the home screen, I get an error message ' no connection: your printer is not connected to a network. " If please connect to a network and try again. "I downloaded the software and latest drivers; my iMac recognizes the new HP printer.  But I must still be able to get the home screen to display on the printer so that I can do the basic settings.  I did the simple troubleshooting suggestions (for example, for printer disconnected from the socket wall and then plugged in;) I restarted the iMac; I uninstalled the software and drivers and reinstalled)... but no change, cannot get the home screen appears.

    The printer turned on, unplug the power to the back of the printer (not the wall) for 30 seconds.

    If this does not work, it seems that your printer is maybe defective.  Here's how to contact HP technical support: www.hp.com/go/totalcare (click on printers & monitors, there is a phone number on the resulting page).

  • How can I get firefox to talk to a second network on my computer?

    I have 2 network cards in my computer. I want to connect to a server on the second network card. However, firefox must be only attempts to connect through the first NETWORK card to the internet. When I enter the IP address of firefox (as Windows to move to the second NETWORK card), all I get is a timeout. It does not connect. How can I solve this problem?

    I'm glad you found the answer. Network issues like that are always a PITA.
    You must mark your own message as the accepted answer. It stops this thread appear in searches of "unsolved problems".

    This route table entry is basically what should have been the default route for this subnet. He should have been there automatically. Basically, if the destination ANDed with the subnet mask equals the table ANDed with the subnet mask entry, then it is and the path through the gateway specified.

  • Satellite Pro P300-19 q - cannot get the Wlan to work

    Hello

    Ive just bought the PRO P300-19 q and as many other people cannot get wifi to register even less to connect to any network. I will say that I am under XP Pro. I've updated all the drivers and everything is enabled.

    If anyone can help with this problem it would be greatly appreciated. It seems absurd that Toshiba or Intel have not resolved that, as the problem is ongoing since 2005 - announcement earlier I found.

    Thanks for your help, Zato.

    Hello!

    You have successfully updated the WLAN driver on the Toshiba site?

    Try to update the BIOS of your laptop. You will find on the Toshiba site.

    You use the same standard WiFi on your laptop as on the router? Check in the properties.

  • Airport Extreme cannot get dhcp network

    Hello

    My main router connected to the internet and to act as a DHCP server, the extreme Apple router can join this network and get IP from the DHCP server normally, but all clients connected to Apple Extreme cable cannot get DHCP.

    I tested the same configuration but replace Apple Extreme by an Apple Express, the customer may obtain the DHCP when connect you cable.

    Anyone has an idea about this?

    Thank you

    Tuan

    My main router connected to the internet and to act as a DHCP server, the extreme Apple router can join this network and get IP from the DHCP server normally, but all clients connected to Apple Extreme cable cannot get DHCP.

    Unfortunately, it is because, unlike the AirPort Express, the extreme can serve as a wireless Ethernet bridge to provide wired clients with DHCP.
