• Controller of domain and DNS behind RRAS without VPN connected directly to the internet with a Cisco router

  I hava a ME Cisco 3400 with physical single port available for a cable connection.

  The ISP give me an IP address interface = 89.120.29.89 to act as a gateway to the IP Address of the host, which is provided for in the order 89.120.29.90.

  The host computer is a dual Xeon computer with two NICs for LAN and WAN.

  Fields of application: to install a windows 2008 R2 between public and private network server.

  Even though I know it's not recomanded, I put the DNS role and directories Active Directory roles installed on the same computer, the computer above, (I do not have enough computer for roles different place on different computers)

  The desired configuration:

  To have installed with his roles behind a WS2008R2 has RRAS. without a VPN.

  b with VPN

  and for WAN access for the client computers of the private LAN Windows 7 OS. (The basin of LAN address 192.168.0.1 - 255).

• WRT54G V5 does not connect to the internet.

  I am replacing a WRH54G with a WRT54G.  First of all, I just unplugged and waited 5 minutes. Then I plugged my ethernet cable from the DSL modem into the WRT54G. Then I plugged the DSL modem. I waited for lights stop flashing. Then I plugged the WRT54G and waited for LEDs show the connection. Then I plugged the cord of the WRT54G to computer ethernet. Then I turned on the computer. I was able to access the Interface for the WRT54G, but I wasn't able to connect to the internet. I tried power cycling several times times the modem DSL and the WRT54G. I was unable to access the internet. Finally, I plugged the WRH54G back in and everything worked fine. Any ideas as to why the old WRH54G can connect to the internet and the WRT54G impossible?

  In fact in the statement above this still does not work, but ten minutes ago I understand much of the useful post. Because I wasn't getting IP addresses on my new router, I was wondering if some how they were blocked on my old router. So here's what I did. I had my old router connected. I logged into the old router and under status I clicked on the release of the WAN IP. Then I unplugged the old router. Then I connected the internet cable from the modem to the internet port of my new router and connected first ethernet port on the router to the computer. Then I connected the new modem. When I logged in I saw that the router had caught the required IP addresses. My internet is now up and running and with the QOS feature on my new router I can watch YouTube and be on my google phone VOIP at the same time with the blurring! The key was to know that the problem was that my new router was not grabbing IP addresses. This gave me the idea that they were somehow stuck on my old router. When I published their new new caught router. I know this isn't technically how it works, but it solved the problem. Ball-shaped here were the steps of the solution.

  Verizon DSL DHCP

  1. connect to the old router.

  2. click on status

  3. click on WAN IP release address

  4. disconnect all cords of old router.

  5 connect the cable modem internet in new internet router port.

  6. connect the ethernet cable to port 1 of the modem.

  7. connect ethernet port 1 of the modem in the computer

  8 connect the power cord to the new router.

  After I did these things that the internet was working fine with all my other stuff related to the router. I connected the new router, looked under status and saw other and valid IP addresses. Thanks for the help. I hope that someone that nice find if they still have the same problem. I wonder how the addresses IP got stuck on the old router or rather why I had a WAN IP release on the old router before the new router could get a valid IP address.

• Implementation of QoS on the border routers

  Hi all

  I have a question about the implementation of QoS in the local network. There are a bunch of L3 - L2 switches with the support of 802.1 p. 2921 SRI is on the edge of the network. I need to ensure service to certain types of traffic in the event of congestion of the uplink to the internet (attached).

  I could somehow score interesting traffic on RSR on the side LAN and apply a QoS policy? What criteria should I use? Thanks in advance.

  Hello

  Yes it is possible. You can try using the model from the following link:

  http://www.Cisco.com/c/en/us/TD/docs/solutions/Enterprise/WAN_and_MAN/QO...

  There are also other scenarios of QoS in the the reference Network Solution of QoS above Enterprise Design Guide.

• When ISE goes down, none of the computers can get to shared network or the Internet.

  We only run Cisco ISE 1.4 with only computer authentication and recently had a power outage for about 6 hours. When the batteries of the UPS drained EHT servers are connected to the, none of the computers could connect what either. The NETWORK card on the computers had an error authentication failed. We "Rescue of unauthorized network access", selected on each computer. Is there a way to allow all computers access to the network and the internet as usual when the ISE servers are down?

• iTunes crashes if its wifi network does not have access to the internet

  Hi all.

  I'm running a 13 "mac book pro with OS X El Capitan.

  I have a very specific problem of iTunes which is really bugging me.  I'm a pro saxophone player and part of my job is performed as a soloist with playbacks on my mac.  To avoid having to walk to the mac to start the track to accompany each song, I use a tablet on a stand that I can place anywhere in the room.  I've set up a router next to the mac that the mac and the tablet of connect to, and I run "retune" on the Tablet (I think it's that his name) which is a wifi iTunes remotely.  Installation is really smart cos he allows me to choose new avenues of selection from anywhere in the room instead of walking back and forwards to the mac every time.

  The problem I have is that sometimes maybe (1 to 5 times), I have a real problem from iTunes when the mac is connected to a wifi network that has no real internet connection.  I'm sure that iTunes detects wifi connection and then tries to access the internet to connect with the store.  When he is not in the store it just crashes and I get the spinning wheel of death.  Most of the time, I can simply restart the program several times and finally he decided to play ball, but it's a real pain.  And I did a concert yesterday where he would not have enough, no matter what I did.  If I had no choice but to turn off the router and keep walking to the mac for each song.

  I can't find a setting anywhere on iTunes that can disable the connection to the store and I really am stuck.

  I also tried alternative programs (I used Clementine briefly but I just found it too flakey to be invoked) and so I am open to others suggests.  But I need a player who has a remote app that I can use on my tablet.

  Thanks in advance for the help.

  I use an older version of iTunes and in the preferences a lot, I can disable Store, Radio, sharing services, probably genius if I got it. Check all your preferences settings including those you think don't matter such as parental preferences (this is where the store is hidden on mine).  Realize also that iTunes has turned into a simple multimedia player to a 75% of sales and marketing as well as the do-it-all tool (aka bloatware) try too many at once and developers can't even imagine someone (i.e. the daily target user) use it without Internet.  Add on that you try to use an application to control iTunes and something like that is likely to misbehave, willy nilly whenever Apple launches an update.

  Don't forget with wi - fi you are subject to interfering signals other wi - fi services in the region or the stage equipment.

• Devices to connect to the airport, but not to the Internet

  Hi all; Here's my situation:

  I just bought a new Airport Extreme to replace my old router (Linksys). In our House, we have two iPhones 6, as well as the iPad, Apple TV and MacBook Pro that were all bought again this year. All these things were able to connect to the internet using our old wireless router.

  As I have configured and installed at the airport, various devices have been able to connect without being able to connect to the internet (i.e. AirPort Utility, the airport connection is a green dot, while the actual internet connection is an orange): first it was the MacBook having this problem while the phones and the iPad have been completely connected. After I simply rebooted everything several times - i.e. the modem, router, and MacBook - I finally got the MacBook fully connected (without really changing all the settings, which are all entered correctly). Now, however, it is the two iPhones that will connect the airport but not actually in the internet.

  Any ideas? I must say, these strange little problems idiopathic who seem to always pop up with Apple products are starting to really bother me... I never got my MacBook to connect to the Apple TV via AirPlay.

  Any time you change the material or providers of Internet services, networking, it's always a good idea to perform a complete recycling of your network equipment power. Check out the following Tip of an airport users for more details on how to do it. Please post back your results.

• Restoration of the Internet does not

  Hello

  So I'll try to get back a mid 2010 Macbook Pro originally OSX from Yosemite. I updated the firmare EFI to enable recovery of the internet, but it doesn't seem to work. It starts at startup (command + option + r) - the world turns, take five minutes to load. But after that, he will not to the choice of language as I saw in the video tutorials. Instead, it is the emblem of apple which lasts 10 minutes or so to load, what I'm met with the covering Panel.

  Other notes: typical restore mode proposes to reinstall Yosemite, while the above method offers to install El Capitan.

  There is no option to install original OSX, which I assume is Lion or snow leopard, etc.

  I tried to boot from a USB key the Mavericks. It loads the recovery screen, as well as the offer to install the Mavericks, but it does not work - probably because the Mavericks wasn't on it always if it is unrecognized.

  I came to the conclusion that there is a problem with the stage of recovery of the internet, which is a disappointment because it's really the only way that I know that I could get back the old version. Is there a way to correct the re-establishment of the internet?

  At the present time I install El Capitan, in the hope it fixed somehow magically internet recovery bit, since I tried so many other things (including assignment to reddit here: https://www.reddit.com/r/mac/comments/53knik/how_to_revert_to_original_os_x_from _yosemite_on /).

  Any tips are appreciated.

  You may need to reinstall your current OS, through upgrading to El Capitan might fix it for you.

  When you start in OS X Internet Recovery now command-Option-r, click on reinstall OS X OS X Utilities page, it should tell you that it will install what was the origin of the computer operating system. If that doesn't work there might be something wrong with the OS or the hard drive itself.

• Instructions for managing macs w ARD on the internet (no static IP address)

  Please excuse me if it's asked all the time, but I searched and can not find detailed instructions for this.

  I need to manage more than one Mac, on connections to the internet, the devices will not be on the static IP, they will constantly be moving around.

  All the videos I have found online seem to show how to connect and manage Macs on LANs w ARD.

  Details:

  ARD v3.8

  All Mac on El Capitan

  Very appreciated for any help!

  This question is not particularly related to Apple Remote Desktop; for ARD.  This is a configuration of generic firewall and networking question, so good enough instructions for your specific firewall will work here, as long as the firewall can redirect ports - port TCP 5900, in this case - or if your particular firewall has a VPN - Firewall Server average range and high-end frequently - or if you can implement a VPN server behind your firewall and configure the firewall to forward the VPN protocols (different ports) and ports necessary for the particular VPN.

  In general...  I would suggest three ways...   1: set up your firewall to port before port TCP 5900 to the client target.   Maybe TCP 5988.   Or set up a VPN server in your firewall and connect to that and use ARD via a VPN.    If you want to access more than one system on the target network, you will need to either use a range of ports to forward to specific systems behind your firewall and happens to be a problem with many customers - I don't know immediately off-hand if the ARD client allows even to select different target ports - or to set up and move to a VPN.    2: creation and configuration of the VPN server in the firewall allows access to all systems on your network target - a VPN connection makes your local system as it is directly connected to the target network.  3: If you have the VPN server running on a target system and accessible through the firewall port forwarding, this target system must always be available, and all VPN traffic is routed through this system.   It is more complex and can also be a bit difficult to set up.

  If you directly expose ARD ports to the Internet via port forwarding, you'll want to either restrict the available source IP ports (to reduce the magnitude of the attackers), and you'll want to be very careful about passwords on target systems.   Ports of the ARD are detected very fluent, and several people and botnets will attempt to access the system password-baited; trying to guess the users and passwords on the target system.   Once attackers have a login and a password, they will then try to spread throughout the rest of the network.  (It's part of why I prefer to use virtual private networks).

  Sierra of MacOS support PPTP VPN, so I wouldn't go with any configuration of VPN that you considered it.   I'd probably use L2TP/IPsec, because the customer is generally available in most of the other operating systems, Mac OS and iOS.

  There is information available on the network ports used by Apple devices.   If you enable VPN port forwarding, there are discussions on the ports and protocols required to according to VPN you use posted around the ' net and not all firewalls is particularly good to port-forwarding, the protocols and ports VPN. "  Low-end older firewalls and firewalls tend to have problems here.

  To locate on the networks of the target systems, you get to use dynamic DNS from client devices or other means to identify the public IP address that is associated with the target customer.   If customers are roaming on disparate networks and not simply roaming IP addresses on their private networks (these addresses can be fixed through DHCP configurations, too) and if you don't have access to intermediate firewalls, then you will probably have to rethink the entire approach, unfortunately.    Connection to mobile systems distance arbitrary is not especially it is possible, he must do something on the client that "tags" or "ad" its network metadata to your own server from tracking client or server monitoring of some other entity (for example messages to the DNS servers used by the dynamic DNS providers), or the management connection must be initiated from the client.    ARD does not support these mechanisms.   Discussions here can get pretty complex, too--in terms of network configuration, both in terms of security for the clients and servers.

  There are a few related discussions this general topic in the forums. See here, here, here, here or here.

  He has worked in the past and now could not or never worked?

  Apple routers can sometimes decide autonomously switch to bridge mode. If your cable modem is not a router, you MUST have the apple router... TC in your case DHCP and NAT mode.

  If you have not done before you reset the TC at the factory and re-do the installation. Here are my recommendations.

  Universal factory reset

  Turning off the TC... That is, remove the power supply cord or the power at the wall outlet, wait 10 seconds... Hold the reset button... be nice... Turn on always even now in reset... and keep holding in for another 10 seconds. You may need assistance because it is difficult to hold in reset and power on. It will show the success quickly flashing led front. Release reset... and wait a few minutes for the TC to reset and return with the factory settings. If the front LED flashes quickly you missed and simply try again. The reset is quite fragile in these... Press the key while it is just click away and not more... I've seen people bend lever or even break. I use a toothpick as a tool.

  NB. None of your files on the hard drive of the TC are removed... This simply clears the settings of the router of the TC.

  The installer the TC.

  Then redo the configuration of the computer that you want to use for TM using Airport utility.

  1. the use of very short names... NO APPLE RECOMMENDED names. Without the space and pure alphanumeric characters.

  for example TCgen5 for the base station and the name of the TCwifi wireless.

  If the wireless is still an issue defined wireless names like TC24ghz and assigned the 5 GHz other name... eg.TC5ghz.

  Finally, use fixed channels in 2.4 ghz... try 11, 9 and 6, in that order.

  (leave the security for a few minutes and see if that makes a difference).

  For iphone and TV with problems in your Setup program ensure that the TC is NAT and DHCP... try to use a different such as google public DNS 8.8.8.8 and 8.8.4.4

  2. use all passwords also consistent with 1. but maybe a little longer. IE 8 and 20 characters of mixed cases and numbers... no alphanumeric non-caracteres.

  ** 3. If the TC is router, you can ignore this point. It is only a problem when the TC is bridged.

  If ensure that the TC is always the same IP address... you will need to do this on the main router using a dhcp reservation... or a bit more complex setup by using the static IP address in the TC.

  Ignore this point if you don't understand it... after the return if you drop questions.

  4. be sure that IPv6 is set correctly in the computer. IE link-local only for ethernet or wireless depending on whether you are using. Car is not good enough.

  Tell us which modem cable, you have, make and model please?

  The TC has problems with some popular brands... one of the SB series a modem port is malfunctioning.
