problem of traffic flow with tunnel created the network with a tunnel to a VPN concentrator

Hi, I worked with Cisco and the seller for 2 weeks on this.II am hoping that what we are witnessing will ring a Bell with someone.

Some basic information:

I work at a seller who needs from one site to the other tunnel.  There are currently 1 site to another with the seller using a Juniper SSG, which works without incident in my system.  I'm transitioning to routers Cisco 2811 and put in place a new tunnel with the seller for the 2800 uses a different public ip address in my address range.  So my network has 2 tunnels with the provider that uses a Cisco VPN concentrator.  The hosts behind the tunnel use 20x.x.x.x public IP addresses.

My Cisco router will create a tunnel, but I can't not to hosts on the network of the provider through the Cisco 2811, but I can't get through the tunnel of Juniper.  The seller sees my packages and provider host meets them and sends them to the tunnel.  They never reach the external interface on my Cisco router.

I'm from the external interface so that my endpoint and the peers are the same IP address.  (note, I tried to do a static NAT and have an address of tunnel and my different host to the same result.)  Cisco has confirmed that I do have 2 addresses different and this configuration was a success with the creation of another successful tunnels toa different network.)

I tested this configuration on a network of transit area before moving the router to the production network and my Cisco 2811 has managed to create the tunnel and ping the inside host.  Once we moved the router at camp, we can no longer ping on the host behind the seller tunnel.   The seller assured me that the tunnel setting is exactly the same, and he sees his host to send traffic to the tunnel.  The seller seems well versed with the VPN concentrator and manages connections for many customers successfully.

The seller has a second VPN concentrator on a separate network and I can connect to this VPN concentrator with success of the Cisco 2811 who is having problems with the hub, which has also a tunnel with Gin.

Here is what we have done so far:

(1) confirm the config with the help of Cisco 2811.  The tunnel is up.  SH cyrpto ipa wristwatch tunnel upward.
(2) turn on Nat - T side of the tunnel VPN landscapers
(3) confirm that the traffic flows properly a tunnel on another network (which would indicate that the Cisco config is ok)
(4) successfully, tunnel and reach a different configuration hosting
(5) to confirm all the settings of tunnel with the seller
(6) the seller confirmed that his side host has no way and that it points to the default gateway
(7) to rebuild the tunnel from scratch
8) confirm with our ISP that no way divert traffic elsewhere.  My gateway lSP sees my directly connected external address.
(9) confirm that the ACL matches with the seller
(10) I can't get the Juniper because he is in production and in constant use

Is there a known issue with the help of a VPN concentrator to connect to 2 tunnels on the same 28 network range?

Options or ideas are welcome.  I had countless sessions with Cisco webex, but do not have access to the hub of the seller.  I can forward suggestions.

OK - so I have messed around the lab for 20 minutes and came up with the below (ip are IP test:-)

(4) ip nat pool crypto-nat 10.1.1.1 10.1.1.1 prefix length 30 <> it comes to the new address of NAT

!
(1) ip nat inside source list 102 interface FastEthernet0/0 overload <> it comes to the interface by default NAT

!
IP nat inside source map route overload of crypto-nat of crypto-nat pool <> it is the policy of the NAT function

!

(6) access-list 101 permit ip 172.16.1.0 0.0.0.255 172.16.2.0 0.0.0.255 <> defines the IP source and destination traffic

!

(2) access-list 102 deny ip 172.16.1.0 0.0.0.255 172.16.2.0 0.0.0.255 <> does not NAT the normal communication

(3) access-list 102 deny ip 10.1.1.1 host 172.16.2.0 0.0.0.255 <> does not re - NAT NAT

(1) access-list 102 permit ip 172.16.1.0 0.0.0.255 any <> allows everyone else to use the IP Address of the interface for NAT

!

(5) crypto-nat route-map permit 5 <> condition for the specific required NAT
corresponds to the IP 101 <> game of traffic source and destination IP must be NAT'td

(7) access list 103 permit ip 10.1.1.1 host 172.16.2.0 0.0.0.255 <> crypto acl

Then, how the works above, when a package with the what IP 172.16.1.0/24 source wants to leave the router to connect to google, say the source will change to IP interface (1).  When 172.16.1.0/24 wants to talk to172.16.2.0/24, it does not get translated (2).  When the remote end traffic equaled the following clause of NAT - the already NAT'td IP will not be affected again (3) when a host 172.16.1.0/24 wants to communicate with 172.16.2.20/24 we need a NAT NAT specific pool is required (4).  We must define a method of specific traffic to apply the NAT with a roadmap (5) which applies only when the specific traffic (6), then simply define the interesting traffic to the VPN to initiate and enable comms (7) corresponding

    I installed a NETGEAR N300 Wireless USB Adapter on my computer which is a desk top Dell 64-bit running Windows 7 Edition Home Premium. There are five computers on my network. Two of the others use the same model of NETGEAR wireless USB adapt. I removed the Ethernet cable after the installation of the wireless adapter. I can say that the new wireless adapter works fine. When I tried to map the network I got the same message that appears in some of these problems: "Windows cannot create the network map. Responses of the other devices on the network are delayed or there is a router on the network incapatible". I have restarted this computer in SafeMode as suggested in the above problems. I tried other things like disabling the wired connection has always existed for the cable. No effect. Then I tried mapping the network on the other computers. All failed with the same message. All the other four computers are 32-bit. Three of these computers are also running Windows 7 Home Premium. They are the best desktop computers. The other computer is a Windows 7 Starter netbook running. It is the 32-bit computer, always using a cable. That will be replaced with the same wireless adapter model NETGEAR. Anyone know how to fix this or is this a bug? It would be nice of the network software of Windows 7 has worked as it is supposed to. TO.

    I went the last wired wireless computer and the problem disappeared. The five computers can view the map now without any problems.

  • Return VPN traffic flows do not on the tunnel

    Hello.

    I tried to find something on the internet for this problem, but am fails miserably. I guess I don't really understand how the cisco decides on the road.

    In any case, I have a Cisco 837 which I use for internet access and to which I would like to be able to complete a VPN on. When I vpn (using vpnc in a Solaris box as it happens which is connected to the cisco ethernet interface), I can establish a VPN and when I ping a host on the inside, I see this package ping happen, however, the return package, the cisco 837 is trying to send via the public internet facing interface Dialer1 without encryption. I can't work for the life of me why.

    (Also note: I can also establish a tunnel to the public internet, but again, I don't can not all traffic through the tunnel.) I guess I'm having the same problem, IE back of packages are not going where it should be, but I do know that for some, on the host being ping well, I can see the ping arriving packets and the host responds with a response to ICMP echo).

    Hi Eric,.

    (Sorry for the late reply - needed some holidays)

    So I see that you have a few steps away now. I think that there are 2 things we can try:

    1)

    I guess you have provided that:

    IP nat inside source overload map route SDM_RMAP_1 interface Dialer1

    Since the routemap refers to ACL 100 to define the traffic to be translated, we can exclude traffic that initiates the router:

    Access-list 100 category SDM_ACL = 2 Note

    access-list 100 deny ip 123.12.12.185 host everything
    access-list 100 deny ip any 10.10.148.0 0.0.0.255
    access ip-list 100 permit a whole

    Which should prevent the source udp 4500 to 1029 changing port

    OR

    2)

    If you prefer to use a different ip address for VPN,

    Then, you can use a loop like this:

    loopback interface 0

    123.12.12.187 the IP 255.255.255.255

    No tap

    map SDM_CMAP_1 crypto local-address loopback 0

    I don't think you should apply card encryption to the loopback interface, but it's been a while since I have configured something like that, so if you have problems first try and if still does not get the crypto debugs new (isakmp + ipsec on the vpn, nat router on the router of the client package).

    Hi Finlay,

    I understand that when you try to create a network location, you get an error.

    The error message you get usually occurs when Windows try to check the subfolders of the parent and parent. If the parent folder is not configured for WebDAV, the connection attempt fails.

    Please see the article below for more information:

  • BlackBerry Smartphones Blackberry "BOLD" - problem connecting Wi Fi "unable to associate the network."

    Hello

    I am trying to configure my Blackberry "BOLD" new, I am new to the platform - from an iPhone.

    Unfortunately, I have problems to connect to my home wireless network. I tried two routers, the first being a pre-configured Tiscali (WPA encryption) and the second a Netgear mine. With the Netgear I tried to connect the Blackberry without security at all and the WEP. The Blackberry scans and detects my network, but is then unable to connect each time. Simply, I get the following message on the phone:

    Unable to connect 'Impossible to associate the network '.

    It really spoil things for me, because it is important that I can connect to the wi fi network. I had no problem before by connecting the iPhone, Nokia or Windows Mobile devices.

    Thank you in advance,

    Wendy.

    You will need to remove your battery, wait a few seconds and then put the battery in.  You'll notice that whenever your blackberry starts acting weird, remove the battery usually solves the problem. Turn off the phone, is a bit like putting your computer into sleep mode more.  Take out the battery if want to make a stop, cold-start of a computer.

  • Printing problems on a M1120n MFP printer via the network

    Hello

    I bought a printer HP M1120n MFP, a couple of months.  I made sure that there the firmware up-to-date and that you have downloaded the latest drivers from hp.com.

    I can print and scan very well from the PC which is connected to the printer via a USB cable.  However, I can not usually print on the network of the other PC.  On the PC, I can ping the printer and I can also see the printer status page if I enter the IP address in a web browser on the PC.  So, I'm sure that there are no network connectivity problems.

    However, when I print to the printer on the network of these PCs, jobs just to stay in the queue for the printer.  Sometimes they print - but I don't see any model when they print.

    I would appreciate any suggestion on what to do, because I have to return this printer unless I can solve the problem?

    Thank you

  • Using CDP to create the network topology diagram

    Hi all

    I'm a beginning network specialist and just thought I would throw this question and see if I can get some answers.  Well, I want to know how I can use CDP to find out our network topology so I can create diagrams and Visio diagrams, or if you know any free network discovery programs out there that can help?  Hey well any comments will be appreciated so thanks in advance and I look forward to hear something!

    When you run 'sh cdp neighbors' it shows you all the devices connected directly. If you then "sh cdp neighbor detail" for each entry it will show the IP address of the connected device. You can then connect to this and do the same thing all the way throiugh your network.

    I think that the COP may be useful for this, but you're relying on the CDP running on all devices. Sometimes it has been disabled for security reasons one must always be aware that there may be devices that do not display.

    As mentioned SNMP is another alternative, but still once, this assumes that SNMP has been put in place the device esch.

    So just be aware that you can not always get the full picture, but a combination of--

    (1) CDP

    (2) SNMP

    (3) running the determination of route router hops show but not L2 switch.

    You should get most of the information. Also, be aware that the internal firewall tend to dirty such things as well.

  • Bug trying to create the link with the Cyrillic characters in URL

    I'm transforming words in my text on the links, but with Cyrillic characters in their URL (such as https://en.wiktionary.org/wiki/ хорошо). The problem is that, depending on how create the link, the page refuses to accept the URL.

    It's my preferred method (which accepts not the Pages):

    1. Write or select the text to be transformed into link;
    2. Press cmd + k;
    3. Paste the URL (https://en.wiktionary.org/wiki/ хорошо) in the field;
    4. Hit enter or click out;
    5. When I check the link, it is www.apple.com.

    The strange is that other methods work very well.

    1 against nature (accepts Pages):

    1. Delete my word;
    2. In its place, paste the URL (https://en.wiktionary.org/wiki/ хорошо);
    3. Hit the space bar (a link is created automatically with the correct URL);
    4. Edit the link that is created and change its text;
    5. When I check the link, he kept correct.

    2 against nature (accepts Pages):

    1. Write or select the text to be transformed into link;
    2. Press cmd + k;
    3. Find a way to build a version with my URL (https://en.wiktionary.org/wiki/%D1%85%D0%BE%D1%80%D0%BE%D1%88%D0%BE) escape sequence;
    4. Paste the URL with escape sequence in link field;
    5. Hit enter or click out;
    6. When I check the link, ironically, is хорошо https://en.wiktionary.org/wiki/.

    To stretch more:

    1. Editing a link created successfully (with any success methods above);
    2. Changed its URL (from хорошо https://en.wiktionary.org/wiki/ to https://en.wiktionary.org/wiki/ плохо)
    3. Hit enter or click out;
    4. When I check the link, it's still хорошо https://en.wiktionary.org/wiki/;
    5. Finally edited and changed its URL still once, now remove the Cyrillic (https://en.wiktionary.org/wiki);
    6. Press enter, click out and he finally accepted the URL.

    Pages seems to be denying the creation of links with the URL that contains Cyrillic characters (only?), but exclusively through his little creation of link popup. I think it's a simple problem, but I'm sure it's very annoying.

    Everyone knows the same?

    Cyrillic characters in the range of table encoding UTF-8 code points u + 0400 - u + 04 FF are represented by two bytes. These people must be encoded as a percentage (read the two paragraphs of the current standard of article), as the Pages v5.6.2 will convert automatically URI to this encoding for you in the link Inspector. It will simply ignore what it considers incorrect URI links, they are Cyrillic, or even English.

    Use what is easier for you, and that Pages v5.6.2 accepts.

  • Not reflected in the network system preferences utility airport settings

    Airport Express model A1264

    Airport Utility 5.6.1

    Firmware 7.6.7

    MacBook OS 10.6.8

    Hello, I am trying to sort out why the Airport utility settings are not the same as the settings in system preferences > network > airport.  If I make a change in Airport utility, it does not change the settings in advance under network options in system preferences and vice versa.  Network names are the same and all other parameters, except the IP numbers are different. (Note: when asked to "Join other network" one and only network name I entered comes up.) All this occurred as a result of a new service by satellite being installed in our premises (I'm in Australia and we have a 'NBN Satellite' service).  IP address in system preferences > network seems to be the IP number, I received when the new system has been activated and the computer that is directly connected by ethernet cable to the modem.   The IP address of the Airport utility is the Airport Express IP number.  I guess that the first IP address is correct as I can connect the MacBook to the internet via Airport. To complicate things, it is that I have the additional problem of not being able to join the network using my MacBook Pro (OS utility 10.10.5, Airport 6.3.5). I get a message telling me to another computer is using IP number again xxxxxxxx test this last (or something similar).  I did originally a default zero value through the Airport utility menu using the MacBook (actually several times), but no change in system preferences > network settings. I think I should add the MacBook Pro Airport utility on the MacBook (which I have) to join the network created on the MacBook.   I use the MacBook for the e-mail and the spread of the internet, and the MacBook Pro should be able to join the network for software and other upgrades. The Airport Express has worked without problem for at least 4 years on our old satellite service. Thanks in advance for your consideration.

    I'm trying to sort out why the Airport utility settings are not the same as the settings in system preferences > network > airport.

    Setting affects only the Airport express airport utility. They do not change anything on the computer.

    Setting in the preferences of the computer only affect the computer... They do not change anything on the express.

    IP address in system preferences > network seems to be the IP number, I received when the new system has been activated and the computer that is directly connected by ethernet cable to the modem.

    Are you a public IP address on the computer? In the old system, you most likely have a private IP address.

    The computer really should NOT directly connect a modem... only a modem which has several ethernet ie is actually a router.

    That will tend to make it more difficult to set up the express. The express should plug a pure modem... and then the computer plug in the express. In this case, the express would be the main router. (I don't like this setup but because the Express is not powerful enough for this job). As far as your express is the old N a wireless with a single ethernet port.

    Honestly, do you a favor and buy another router from apple... the extreme... If you can't afford a new Gen6 then buy a Gen5 on ebay... around $60... immensely better.

    The express can then extend the wireless... or just simply do serve airplay etc. as part of the network.

    Tell us what model is the modem (+ router?) provided to you by your ISP?

    And if you get a public IP address or private on the computer directly connected to it. We can work out the rest from there.

    I'm in Melbourne... you can email me direct if you need to. Email is on my website.

  • Using too much CPU only when loading the network

    When FF works closely with the network (wired or wireless) card for access to the network, CPU utilization spikes in way more than 70% and he stayed there until the page loading process finishes web.
    After the upload is complete, the CPU usage remains somewhere between 5-10%.

    When I look at clips youtube 1080 p, where FF is duty next buffer part of this clip I watch, new CPU use peaks above 70% with the flash plugin and gives a total of a 100% of cpu for a few moments and use which make this clip to stop playing or to frame bad times, and ties.

    I have been activated in about: config webgl acceleration to activate the force and that much improve the initial problem, then I activated gfx.direct2D - activated force and also to improve the problem remaining.
    I also disable the safe_mode parameter file adobe flash config protectedmode = 0.

    I have to mention that the initial problem was way to bad ... 
    

    Now I get to point when I don't know what to do so that FF does not use much CPU loading pages.
    As you can see I use to publish this version of Nightly 64 bit (I think it's the 64-bit version...) which is much more better and I would like to read youtube 1080 p clip normally, after that I have wait a few moments to buffer, before starting to play.
    Version 32 bit FF won't let me watch YouTube without framing hurt when the clip is buffered.

    I was monitoring the Task Manager and all the processes listed... and there, I can't blame antivirus or firewall to the peaks of the processor. Also if I do the rest of the network traffic, as well as inside the network custom CPU even file copy flinch.

    Can someone help or give an opinion on what setting to do, so I can eliminate these spikes?

    Thanks in advance!

    Problem solved partially:

    I have observed that the CPU spikes occur not only while I use FF or mozilla nightly, but on all web browsers (Chrome, IE, Opera, etc) that I have used, while these browsers accessing the network.

    Uninstalling the firewall of the solution of the AV portion has helped a lot and by also disabling the bed in the firewall solution of W7, but for long term use, this isn't the right answer (for my at least). Without any firewall FF work or installed works like a charm, while the CPU usage is increased at a decent level of 50% max (total tasks and running services)!

    Anyway, as I said earlier, my pc without any firewall operation is not a good think to do, so I'll replace my computer with a faster, or I'm going to overclock it at a level that zapping INTERNET and navigation will not infringe too much on the performance of the system, or... I live whit it and I accept the limitations...

    Perhaps, in the development of the FF, programmers will keep in mind that not everyone on this planet has powerful processors - and... give a few options... to decrease the CPU at acceptable levels, event, even if they use the firewall solutions that violate on the CPU while FF is buffering of data across the network.

    I should also mention that Mozilla nightly (64-bit) and FF, are always better then IE - in my opinion - which is.
