Failure of WAN connectivity

• LRT224 hickups: abandon the WAN connection?

  Hello

  my new LRT224 shows hickups in my regard.

  It is connected to a fiber-optic 100Mbps of my ISP connection.

  If I try to stream video, it creates every minute or so a second or two to break up the transmission.

  Obviously, this breaks my video stream.

  The newspaper of the device (see below), says 'WAN connection fell', which seems rather strange and unexpected for me.

  If I don't stream video and data binding is almost at rest, these messages of 'WAN fell' intermittent continue.

  If I take the LRT outside and connect my PC directly to the line of ISP (Yes, bad practice) I don't have these hickups, and fine video streams (to a few Mbps).

  I have updated the firmware to v1.0.1.01 but that has not made a difference.

  In fact, I have disabled the 2nd WAN port.

  "Dual WAN', the 'activate the Network Service detection' is not marked in the config. By selecting "Connection failover" or "Load balance" shows no difference (no improvement).

  No idea why the LRT report "WAN connection is dropped?

  I need urgently a solution, but the issue seems beyond my skills...

  (In the newspaper, I also see "violation of policy. I don't know why they happen: I have no rules of firewall on the LAN or WAN IP addresses...)

  Thanks for any idea!

  Hello

  Thanks for your replies!  I looked in the settings and methods to verify this behavior.

  In the end, I decided that the behaviour of "drop the WAN" is not not to blame the LRT224: it seems really to be created by the ISP (the fiber modem): when I plug a small switch between the router and the modem 'abandonment WAN' messages have disappeared.  Now I 'just' convince my ISP to do something...

• RV082 abandons a WAN connection immediately after creation

  I have my 2nd WAN connection on the RV082 setup to connect via the static IP address for a T1 connection. When I connect the cable, reports the newspaper...

  «WAN connection is in place: 216.130.xxx.xxx...» "and 3 sec later reports"connection to the Wan is down. "

  Can I connect a computer directly to the T1 with the same static IP settings, and it connects without problems.

  I'm on firmware version v4.0.2.08 - tm.

  Any thoughts?

  Have you tried changing the WAN2 connection with the WAN 1 connection to see if it will stay connected? You use Load Balance?

  Also for the connection that may not be not connected trying to bump on the MTU to perhaps 1492 and see if that makes a difference.

  Thank you

  Hello

  1. you are using a wired or a wireless connection?

  2. If it works well before?

  3 did you changes to the computer before the show?

  Method 1: Reset the router and see if that helps.

  Note: To help you reset the router, you can consult the manual that came with the router or the router contact manufacturer.

  Method 2: Uninstall and reinstall the NIC drivers and see if that helps.

  See the following steps:

  (a) click Start, right click on computer.

  (b) click on properties, click on Device Manager

  (c) expand the network card, right-click the wireless adapter option

  (d) click on uninstall

  (e) now go to your computer/wireless device manufacturer's website, download the updated drivers and install them.

• Cisco VCS error: temporary failure / new necessary connection

  Hi all
  I am writing this new post for support to the installation of the VCS (VCS Expressway + control) system.
  In my case, I have 4 levels of firewalls (Juniper A - Checkpoint - Highway - Checkpoint - Juniper B - Control), where A is external genever that performs NAT.
  At this point, I can make calls back and forth if I place the video-terminal external between Juniper and the control point (with a private address). If I try to put the video-terminal outside Juniper a NAT on this FW clearance and enable NAT application on the highway (with the public IP address), the call rings, but when the internal video-Terminal accepts the call, so that it that the call is connected (no audio), the appellant continues to sound as if no one answered.
  Go to see the logs on the systems I have this message in venture capital:

  Temporary failure / new necessary connection

  go and see the details I have:

  Call disconnected, Message sent, Grželj = ' temporary failure of Q.931 Cause, H.225 Cause: new necessary connection, more info: None.

  A that someone already had this problem? Someone who can help me to locate where is the error?
  Thank you very much!

  Federico,

  for traffic between VCS - C and VCS-E, the following ALG could impact:

  SIP

  Q931

  RAS

  H245

  In other words, all those which you have listed outside of RTSP. I would recommend that disable you SIP, Q931, RAS and H245 ALG, at least for the exchanged traffic between VCS - C and VCS-E.

  Let us know how it goes

• VM 2 or more share a WAN connection

  Hi all

  Excuse me move if this is the wrong place for this post, etc...  Relatively new to ESXi and I don't know if I want to do is possible.  I have a Server with 4 GB Supermicro intel NIC.  I have one of these NICs connected to my internet provider (WAN) and the other for the HP ProCurve (LAN).  I'm testing different solutions UTM/Firewall (pfSense, Sophos UTM, etc.) and would like to have at least two of them operational at the same time.  The problem is that if it gets turned on first gets a WAN IP and take "control" of the WAN connection.  Whatever it is started after the first primer fine but the WAN interface will not obtain an IP address and be down. 

  Some thoughts that I had were perhaps to be the gateway to the virtual computer to imitate the same MAC address, I found a few posts that seem to indicate that Comcast modem binds to the MAC for something like this the first connects to.  Has begun research on this so I do not know how 'true' which is, or even if it is if it would help me get to where I want to be.  I hope that he stays the way to achieve this using vnetworking ESXi.

  In any case thank you for your time and I really appreciate any help you can provide!

  Having your machines virtual theft same mac will be chaos in the networking and a damaged arp table. The problem here is that your internet service provider provide only one device with an IP address. How to solve this problem is to have a router/firewall VM that is the only internet available VM and then have the other virtual machines behind it and use the port forwarding.

  Another solution is to use a loadbalancer as Kemp, where you can use expedition based URLS and so on. In short, do NOT spoof mac address, it will just make chaos.

• WAN connection between security and connection of servers?

  Hi all

  one of our clients wants to place its servers view Horizon 5.2 security in remote data centers and servers to connect in their headquarters. They have two DMZ environments to hosting provider data centers and they want to fill it with 2 security servers each for redundancy. I have currently no accurate information on the speed and latency (and packet loss). I know that connection servers sharing the same ADLDS need connection to the LAN due to replication requirements strict, but what security servers?

  Can I put my security servers in a region far away and have them matched (and PCoIP routed by gateway) with servers to connect to Headquarters via a WAN connection?

  Kind regards

  Jacques.

  That's fine, as long as they have properly configured firewall rules, but I have to ask: what are they hoping to win this configuration - is-to-end latency lower and upper for remote users of the local data center and then goes on the link of the site, instead of going on the internet directly to the headquarters of the bandwidth?

• Use WAN connected airport Time Capsule as a wireless access point

  I had to replace a failed 4 Gen Time Capsule. I tried to install a new Gen 5 airport TimeCapsule via WAN and set up the airport to act as a wireless access point. It is installed in an area of my house with wireless coverage. In the network of AirPort Utility Mode section, I chose "extend a wireless network. The TC is restarted, I get an error message cannot find the intended wireless network.

  What I lack?

  "Extend a wireless network" is a parameter that is only used if the time Capsule need to connect to another router from Apple with the help of a Wi-Fi connection.

  You use Ethernet to connect, you must use the parameter to "create a wireless network. Use the same wireless network name and the same password as your "primary" router

• Problems of WAN connection after a clean install of Vista

  Since I had my computer wiped out I can't connect to my router wirelessly. is it possible to reformat my WAN settings or anything like that to be able to connect again? right now it says everything is ok but when I unplug the ethernet cable it disconnects me.

  I suggest that you remove all the connections your computer wireless (after writing on the correct settings if those here is actually good) and start again from zero setting of the wireless connection and network connections as well.

  If this does not work, then I call your provider access and explan the situation and ask for their help.  I did it myself several times and they have been very helpful and usually solved the problem (unless it was something on their servers, or on the actual line).  Ask them to walk you step by step in the installation process (seting another account if that makes things easier) and see if you missed a step somewhere.  Ask them to test your modem for problems remotely.

  There may be a problem with the wireless card drivers. Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need to get drivers (and you should do sp RPF bore; ess card amd the router if it is delivered with at least, and all you have time to do - they can help way beyond simply solve this problem), let the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows:http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.

  How your computer was wiped out?  Was it a power surge?  There may be damage to some of the features (like the wireless card) caused by the same incident, but not detected so far.  If you have a spare wireless card or that you can borrow one, then we could test if the card itself is the problem by reversing the it between computers.

  You have other computers connected to the router or the wireless device and do they work?  Perhaps someone with a wireless laptop can drop by for a visit and see if this computer can connect wireless - then we can suspect the router or wireless device.  Do you know how to to access the settings of the wireless device or router to your PC - contact the manufacturer to see if there is a way and then check the settings.

  I hope this helps.  Keep me posted.

  Good luck!

• multi layer switches and wan connection

  Hello world!

  I have a few questions.

  modular switches provide only ethernet ports? I saw some pictures of modular switches, none of them shows any of the interfaces series.

  Say that we have on both sides. The two parties have switches multi - layer. These ratings were to be connected by the T1 line. Do I need a standalone router on each side to connect via T1?

  Thank you very much!

  Hello Sarah,.

  your interpretation is correct: only C6500 high-end multilayer switches can accommodate ports using two Flexwan WAN (which allows to re-use adapters to port the C7200 and C7500 up to 2 PA in a flexwan) or SIP linecards with adapters SPA.

  If in most cases a T1 connection is managed by a border router that connects with a multilayer switches LAN liaison

• the WAN connection becomes too slow after you have configured the VPN (Site Site)

  Hello

  I have two branches connected via WAN (MPLS) connection using two 2921 routers.the connection is 2 M.

  I set up a VPN between these two sites, but after the connection has become very slow.

  y at - it something I can do to speed up the speed of connection.

  VPN proposals are:

  Proposals of the phase 1: 3DES, pre-shared,.

  Phase 2 proposals: esp-3des esp-sha-hmac

  I don't think that lower levels of security proposals will add a lot to the speed...

  Hi Marc,

  one thing you should definitely is a hardware encryption go if you do not already tht, it also reduces the load on your cpu

  You can try other things is play with mtu, according to your line mtu and what applications are mainly used. try setting the mtu of at least 60 odd bytes lower than the mtu and also sometimes server line recommended mtu settings like server many have obligation to mtu to 1300 or 1400, if that's not it can cause a lot of re transmissions, you can also try fragmentation before encryption

• How to use a VM vyatta to manage my LAN/WAN connections?

  I have a simple problem that is hard to explain, so please bear with me. I am using a router Vyatta VM to manage my local network. I have connectivity thoughout my local network but I cannot go outside my local network of the virtual machine. I have a linux box running ubuntu 8.04, vmware server 2.0.2 + vyatta VC6. eth1 on the box gets a public IP address from my ISP (we tell 1.1.1.2 for demonstration).

  eth1 has an eth1.2 to interface VLAN with private IP 192.168.1.2/24.

  I have some maps more who are bridge interface br0 with IP 192.168.2.2/24.

  Ubuntu eth1 (1.1.1.2) <-WAN

  Eth1.2 Ubuntu (192.168.1.2/24) <-LAN 1

  Br0 (192.168.2.2/24) Ubunru <-LAN 2

  Vyatta eth0 (192.168.1.1/24) is filled to eth1.2 <-LAN 1

  Vyatta eth1 (192.168.2.1/24) is bridged to br0 <-LAN 2

  Routes on the GNU / linux and vyatta appear to be configured correctly, but I can't do a ping of the Vyatta VM to the internet (say google http://74.125.45.105) or my gateway address ISP 1.1.1.1 that, however, I can ping from the Vyatta VM to the linux box eth1 1.1.1.2, which is a "public" IP address I thought I'd add a static route to 0.0.0.0/0 next hop 1.1.1.2 would do it but still no cookies. Someone knows what's the problem?

  Graphic text

  192.168.1.1-> 192.168.1.2- >-> X WWW 1.1.1.2

  Vyatta VM Ubuntu Ubuntu

  eth0 eth1.2 eth1

  Since Ubuntu (gateway) can access the internet and vyatta can ping ubuntu, supposedly yor vyatta traffic should also masquerade by ubuntu to the internet.

  Could you try Internet (ICS) Login Script scipt below:

  Download ftp://ftp.no-x.org/vmware/ICS2

  Download on Ubuntu

  Change and replace INET_DEV with Ubuntu device which the connection to the internet (for example, eth1)

  chmod + x ICS2

  Run it $. / ICS2 start

  Test your vyatta

• Can I use Airplay with an Airport Express station and a MacBook Air without going through a WAN connection?

  I want to set up my MacBook Air and an Airport Express so I can use iTunes and AirPlay to connect wireless to the AirPort Express Terminal and connected powered speakers to listen to the music in my iTunes library. Is this possible? I don't want to connect to an existing wireless network to do this. I want that this configuration to work wherever I am regardless of the availability of an existing WiFi network. I want a direct wireless connection between the MacBook Air and the Airport Express. Can anyone help with this?

  Thanks for your help in a confusing question.

  Yes, it will work.

  You must configure the Express in router mode... the EXTENDED network of the give a static IP address and ignore the problems. You will get several questions... because the network is internet-facing. They can all be ignored... This is how it is.

  You can also use a static IP configuration. I use this on a TC, but the same configuration on an Express might work better than router. It can be a delicate touch of the installation. So after some screenshots if you are having problems.
