• RVL200 error message: DHCP IP address range into conflict with the LAN IP address

  I have a RVL200 (firmware v1.0.12).  I use it mainly as a firewall, but also taking advantage of the DHCP server on this subject - at least I thought I was!

  When I configured the RVL initially (several years ago), I have it has assigned an address 192.168.0.128 LAN IP and enabled the DHCP server.  The DHCP address for the allocation range is 192.168.0.100-. 149.  I have not assigned a DNS server address (don't remember why not - maybe - because of the same issue, I'm now face).  Since then, whenever I have to appear a new PC on my LAN I put client PC using DHCP to get an IP address... but I need to manually specify the DNS server address (which is logical in the light of what I have described so far).

  The question I have now is that I want to assign the DNS server address on the DHCP server on the tab Configuration RVL, so my client DHCP PCs will automatically resume the DNS server address.   But when I enter the address of the local DNS (192.168.0.1), the RVL gives me the error message listed above (conflict IP range).  I can't understand why...

  The "strange thing" I see is the DHCP of the RVL / status tab - at the top of this tab it lists the DHCP server address is 192.168.0.1.  This is the address of my DNS server / domain controller.  And the IP address of the domain controller is assigned statically (if it matters).  So I do not know why the RVL shows the DHCP server or my DNS server / DC, rather than showing his own address de.128.  Or why I get this error message when I try to enter the address of the DNS server?  Just as an experiment, I also tried entering the other IP addresses, just to see what happens (all on the local subnet)... and they all return the same error message.

  Any ideas?

  Thanks in advance.

  1. the address LAN IP of the RVL shouldn't be in the DHCP address pool. I guess that causes the error message when you try to change the settings for the DHCP server.

  2. I would say that you Flash the latest firmware 1.1.7 on your router. Read the release notes.

• Client DHCP is unable to get a valid IP address from the DHCP server.

  Client DHCP is unable to get a valid IP address from the DHCP server. I have a home edition of Windows XP attempts to connect to my router wirelessly with wireless or wired connection but I get an error in Event Viewer with the discription DHCP 1007 error message. From what I researched, I discovered that the DHCP service depends on the AFD, TCP/IP and NetBT services. All these services are correctly place and worked very well (even the DHCP service is running without error) but every time I try to release/renew my IP address I receive than DHCP warning in the case where the viewer and I just cannot get a valid IP address of the server (router) I also have one of these verizon wireless G3 usb adapters and it works fine. I also have a good ping back when I try to do a ping localhost (for the closure) I also tried the preinstallation of uninstalled drivers from the adapter/s and nothing works. The only entrees in the registry for DHCP error are also AFD, NetBT and TCP/IP nothing else there, also all the files in the/system32/drivers afd.sys netbt.sys and tcpip.sys in addition to solve the problem, I'll mention that I installed and reinstalled Northon earlier, I do not remember if the problem appears before or after that. I receive also any error or warning in the security log or at least I don't know how to read: P

  Thanks in advance

  Thanks for the information.

  I hope you know that it is risky to connect the laptop to the Internet with no firewall and no antivirus... If this laptop is already connected to the Internet in this State, he is perhaps already infected.

  You said you know the router works because the other computers can connect successfully to it.  You should check the configuration of the router to make sure that it is not configured to limit the number of IP address it supplies, and (b) it is not configured to filter users by MAC address.

  When this laptop is connected by Ethernet, even if he gets the IP address of 169.254.x.y, can you ping the router?  Find the IP address of the router on any computer connected to it by running the ipconfig command in a command prompt window.  The "default gateway" is the IP address of the router.  Run the ping command in the command prompt window as well.

  If the ping is successful, it is possible that you might be able to use an IP address in the correct range for an Ethernet cable (but I doubt that it works for the wireless).

• DHCP server press PowerConnect 28xx series / address pool by VLAN

  Hello

  I am reading the manual of the PowerConnect 2824.

  I am considering buying this switch, but I have a question related to the functionality of the DHCP server.

  Here my question: I want to have different VLAN and use the feature of DHCP server on each of them. Then can I have different address DHCP pools by VLAN?

  Example:

  1-16 ports VLAN1: IP subnet 192.168.1.0/24

  VLAN 2 ports 17-24: IP subnet 192.168.2.0/24

  The manual is not clear on this.

  Your help is welcome.

  Kind regards

  Tom

  Daniel,

  Thanks for the reply. Another question does this mean that the 28xx series switch DHCP server, recover the IP address (from the range configured) on all the VLANS configured? So if a device on VLAN 2 issued a request DHCP, it will get an IP address from the same pool as for example a device on VLAN 1.

  Kind regards

  Tom

• Pwerconnect 6224: vlan client computers do not receive the ip address of DHCP server on a different VLAN

  Hello

  I have a prolem routing dhcp requests between the vlan management where DHCP server resides and the other VLANs.

  I have the scenario of base with three VLANS: vlan 10 (management vlan), 20, 30, configured on a Powerconnect 6224 switch L2 mode. This switch is connected to a pfsense router. The router is configured at the package of road between the VLANS and it does it well.

  In Vlan 10, I have a configured DHCP server to use the ip addresses of all the VLANS (10, 20, 30). VLAN 10 client computers receive ip address but not others from other VLANs.

  When I put the ip address in the appropriate range of VLANs manually on computers, I ping the server and I have connectivity.

  This suggests that the problem is with the dhcp package.

  The following is the configuration of the switch:

  The DHCP server stores information that could be useful? May need to configure monitoring ports and something as wireshark to monitor DHCP packets. This would help determine where the package is stopping.

  example:

  Console (config) #monitor session 1 source interface 1/g8

  Console (config) #monitor session 1 destination interface 1/g10

  session mode 1 #monitor console (config)

  right now I don't see anything in the config of the switch that stands out. If the DHCP server is configured for option 82, then you will need to include the following command on the switch.

  Example:

  Trust l2relay console #dhcp (config-if-1/g1)

  But I don't think that's our scenario here.

• Get a strange IPv4 address of the DHCP server

  Hi all

  As title, I got a strange IP - DHCP server 169.254.XXX.XXX.

  I used Wireshark, tried to get the bootp packets.  I found that my laptop 169.254.xxx.xxx used as source address to send DHCP Discover.

  In addition, there is an option called content with 169.254.xxx.xxx requested ip address. Like my source address.

  I couldn't access the Internet with this IP address.

  I was wondering, is that it is a normal behavior for windows 7 to use 169.254.xxx.xxx to send DHCP Discover?

  A DHCP request is sent through the universal 255.255.255.255 broadcast address which is one of the addresses that a server is listening. The query includes the MAC address of the applicant unit because at this point, it doesn't have an IP address. The DHCP server responds to the MAC address in order to assign the address.

  In your case, the range 169.254 is called the APIPA address and the PC actually assigns to himself because he did not see a response from the DHCP server. As you refer to Wireshark having a reading of the present.

  http://wiki.Wireshark.org/APIPA

  The customer may not send the request via this address and get a response because the DHCP server is not listening on the address or by using the range. The answer must be done via the Mac.

• If a PC with a DHCP server is connected via VPN, with her serve IP addresses on the tunnel?

  Situation: we have a few portable computers test Ubuntu running DHCP servers.  We need get the updates and other changes in corporate network sometimes.  Today, we turn off the DHCP server, set up to get an IP via DHCP (besides) and make our updates.

  Problem: we do not want someone accidentally connect the laptop to the corporate network, while its DHCP server is running.

  Question: so, if we go via wifi using a Cisco VPN client, the DHCP server IP addresses above the tunnel?

  Thanks for reading.

  N ° DHCP uses layer 2 broadcasts to disseminate IP addresses.  Because your clients are connected via VPN, there is no contiguity of layer 2.  The only way he would accidentally do it is if you have configured an address to support IP dhcp as one of your VPN clients on the network, which I imagine you wouldn't.

• ASA AnyConnect client is unable to obtain the IP address of the remote DHCP server

  I and ASA with 10 client AnyConnect profiles set up to get their IP address of my Windows DHCP server.

  It was working fine yesterday.

  I saved the config and rebooted the device.

  Now it won't deliver to my vpn clients intellectual property.

  I don't understand what is happening.

  If I change the profiles to use a local pool he assigns an IP address and works very well.

  But I can't use the local pools.  I have to use the DHCP server on the local network.

  Well, your config looks good. You also upgrade the operating system? Maybe you hit a new bug.

  I heard no problems after the installation of a license, but it might be interesting to open a TAC case and learn if you hit a bug.

• DHCP server does not start - the storage control block address is invalid.

  I use a trial version of the Pro Workstation 12.1.1 on Windows 10. I seem to have a strange problem where the DHCP service does not start.

  I tried to go into the virtual network editor and then restore the default settings, which had no effect.

  The event viewer displays the following text:

  CreateFile Version ioctl(): VMnet8 (327680 393216): the operation completed successfully.

  / The storage control block address is invalid

  Checked the service and it runs under a local, verified system account permissions on the config dhcp / rental file in c:\programdata\vmware\ and both have system configured to full control. I tried to run the vmnetdhcp.exe in a command prompt to we hope to get additional information, but cannot be executed directly. I can't figure out how to get out of documented logging dhcp server in order to track down what could be the culprit.

  I tried to uninstall workstation, restart, reinstall, restart both unsuccessfully. I had version 9 workstation that was installed previously, in which the trial upgrade.

  Any suggestion would be appreciated.

  Figured it out.

  It appears during the workstation installation 9, he placed vmnetdhcp and vmnetnat in c:\windows\syswow64 folder. Pro 12 workstation puts these files in the default directory (C:\Program Files (x 86) \VMware\VMware workstation). The service was always pointing to the old location even SysWow64 after an uninstall and reinstall.

  I replaced the files SysWow64 folder workstation and services started right up.

  Checked the work by selecting NAT and gets an IP address from the host machine.

• Can not get the comments DHCP server to allocate addresses on VMNet1 Host-only network

  Hi all

  Hoping someone can help with this question, here's my virtual machine configuration basis up to now:

  -Windows 2012 ADDS, DHCP, DNS server

  -Windows XP client

  The two guests use the network to host only VMNet1 and DHCP is disabled through work stations.

  The problem I have is that my Windows XP computer cannot get a 2012 server DHCP address and she comes back with the link-local address of 169.x.  If I configure my Windows XP machine with a static address on the same subnet as the two computers are able to communicate without problem, so I'm not sure where I'm wrong.  Wireshark shows the broadcast DHCPDiscover packet, but nothing is returned.

  These adapters have certain limits they can treat broadcast packets?  Or am I really missing something here?

  Any help is greatly appreciated.

  Thank you!

  Did you check the configuration of your Windows Server 2012 DHCP server? The scope is active? The server is OK?
