• DHCP Server address range

  Hello

  I was wondering if there was a way to change the integrated DHCP server address range of 192.168.1.x for, say, 192.168.0.x?  For example, when you change the IP Address of the router from 192.168.1.1 to 192.168.0.1.  I noticed that when you post such a change, the DHCP range does not update accordingly.  Any ideas?

  Thank you

  Paul

  Your range of DHCP server should update automatically to the 192.168.0.x subnet when you change your "local IP address" in 192.168.0.1.   Be sure to use a computer that is connected to your router when you perform this operation.  In addition, be sure to click 'Save Settings', and then to wait (from 3 to 60 seconds) screen refresh.  You will be probably disconnected from the router when you perform this operation.  Don't worry about this.  Turn on the router and your computer.

  Then, wait 30 seconds, and then restart the router and the computer.  Now, your local IP address and range of DHCP servers should have the same subnet.

• 6248 VLAN do not receive the DHCP scope

  I created two new DHCP scopes in my windows server 2003:

  192.168.2.0 - public, and
  192.168.3.0 - VOIP.

  This DHCP server is connected to a Dell powerconnect 2708, which is connected to our new powerconnect 6248P via fiber point-to-point.

  In the new computers on network on the default 1 VLAN are correctly attributed IPs as they connect.

  I issued the following commands to the 6248 CLI:

  Enable

  I also added all traffic on VLAN 20 and 30 of VLAN on ports 1/g11 (6248) and port 2 (2708). VLAN 1 access was removed from ports 1/1/g1-g6 (6248)

  Everything seems to have been set correctly, but I can't get a response from the DHCP server on all ports attached to VLAN 20. The powerconnect 2708 switch is unable to pass the baton to the server? Is it possible that something falls in the point to point?

  I would greatly appreciate any comments or suggestions, thanks!

  The 6248 has no default gateway. It wont let me put 192.168.1.1 because he does not reside in the same subnet as the 6248 (192.168.99.1)

  The 2708 has listed 192.168.1.1 as its default gateway.

  At this point, the network has too many complexities for me to unravel. I am very happy that at least I solved for DHCP when we finally migrate our server to the new location.

  Once the server is up, and the gateway/firewall are directly connected to the 6248; I will review the correct configuration of this network.

  Some advice to those who might have a similar problem: check your management VLAN. It may not be the same VLAN 1 if you plan to routing to work from VLAN 1 to nowhere else because the VLAN management cannot be routed. Also check static routing of your access point, make sure the front door has a return of the ips of your VLAN, IE: 192.168.2.0 255.255.255.0 gateway_ip

  That's all for now. Thank you to all who have contributed

  How can I move the outlook express emails from an XP PC to an another XP PC that has the same e-mail address without overwriting existing messages on this second PC?

  I need to group together all messages from e-mail in a PC and to retire the first PC.

  This could be problematic. I guess or OE is over? This would make it easy.
   
  One thing you could do requires some manual work, but much less removal of dupes. For example, the Inbox. In the machine, you are going to scrap, create a new folder and move all messages in your Inbox to it. After you import on the other machine, you can drag the messages you need this folder in the Inbox, and then remove the user created the folder.
   
  And then there are tools to remove the dupes. This one for example.

• 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.

  Adam

  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.

• Since the (all updates) update yesterday, I find one inactive (used only for vpn) network adapter waiting for DHCP Ip address. 1 minute. This should not happen.

  This adapter (or should I say windows) should not ask an IP address until it is in use. There is no difference if I disable it in Device Manager. I get the following error (ID 1001):

  Your computer not was not assigned a network address (by the DHCP server) for the network card with the address...    The following error occurred: 0 x 79. Your computer will keep trying... Since the server (DHCP).

  The MAC address is the MAC address of my "virtual" network card

  In the meantime my physical network adapter does not work. It seems windows is just to wait a response "who will not to pass" a DHCP server which unless I launch the VPN software is simply not going to work.

  I suspect that it is the result of an update that should not work this way.

  Any suggestion is welcome.

  Thank you.

  I would just add - it may be important for long-term understanding of the issue. In network connections, the VPN arrested projected map (still there in Device Manager). I see only the physical card. After removing both and reinstall the two becomes visible. The previously hidden map (vpn) becomes visible. It was not until the physical adapter has been reinstalled (logically). Personally, I have no idea why this I messed up. There should not be.

  Best regards, Dave.

• How to exclude from the SOUL of the rules if the invoice distribution amount is < 0 (i.e. the negative amount) to the existing rule

  How to exclude from the SOUL of the rules if the invoice distribution amount is < 0 (i.e. the negative amount) to the existing rule.

  Requirement: I have an obligation to send the invoice approval group approval specified when the invoice distribution account is 4567 and charge the amount of distribution > 0

  Finished configurations:

  1. Set condition: the string value to using 4567 supplier_invoice_distribution_gl_account attribute
  2. The condition set: SUPPLIER_INVOICE_DISTRIBUTION_AMOUNT is greater than or equal to 0
  3. Definition of new rule setting the terms of the 1st and 2nd stage and also group attached to this rule approval

  Note: Approval is not required is defined for invoices IN. matched in SOUL.

  Test case:

  1. Corresponding invoice with PO (PO amount is 8000)
  2. Amount of invoice header 5000
  3. Distribution account invoice 5568 as well as the amount is 8000
  4. Inserted 4567 distribution and quantity is - 3000

  Behavior of real: system sends the approval of the Bill for approval related group account 4567

  Expected behavior: invoice approval status should be 'Not necessary', since it is a corresponding purchase order invoice and 4567 account amount is < 0

  Kindly let me know how to set the rule to exclude the ve - amount distribution associated with lines

  Hello

  Then set a rule all 3 conditions:

  If attribute SUPPLIER_INVOICE_DISTRIBUTION_PO_MATCHED = No. and the SUPPLIER_INVOICE_DISTRIBUTION_AMOUNT attribute is less than the 0 attribute and supplier_invoice_distribution_account = <> then no permission.

• 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.

• Default DHCP scope

  How can I change the 192.168.1.x for 172.16.2.x's default DHCP scope?

• Addition of wireless routers in series with the existing network

  I have a client who wants to add at least 3 Wireless throughout their existing network routers. The problem is that these routers must be in the same subnet as the existing network. Oh, we use routers Linksys WRT610N. By default, routers set up a new subnet with a DHCP assigned IP of the primary subnet. I was able to change the static WAN IP, but I do not know how to configure the rest. The point of this is that if a user connected via the ethernet cable or wireless signal, they should be able to access the same network resources. I chatted with support, but they are not allowed to help what it isn't is not a "standard" configuration Anyone can shed some light on this subject? I've done this before with another customer, but its been a few years and it's a different router.

  Thank you!

  You don't want a router. You want a wireless access point. You have wireless routers that you do not use as routers, but only as access points. A router by definition routes traffic between several subnets connected to the various interfaces (LAN and WAN). This kind of configuration is not what the WRT is built for and that's why support said you that it is not a standard configuration for a WRT.

  You can use a WRT as simple access point.

  Reconfigure the router via its web interface. Connect a computer to the router first.

  1. set the LAN IP address on a free IP address in the existing network.
  2. make sure NOT to set a static IP address on the type of internet connection.
  3. on the main configuration page turn off the DHCP server.
  4. now save the settings. You will lose the connection.
  5. unplug the computer and one of the numbered LAN ports of wire to your existing network.

  Now you can access the web interface of the WRT to the new LAN IP address. All wired to the other 3 LAN ports and everything wirelessly connected has access to the network directly.

  Hello

  The DHCP Dynamic Host Configuration Protocol () is a protocol for network configuration for hosts on networks IP (Internet Protocol). Computers that are connected to IP networks must be configured before it can communicate with other hosts. The essential information needed are an IP address and a default route and the routing prefix. DHCP eliminates the manual task by a network administrator. It offers a central database of devices that are connected to the network and eliminates duplicate resource assignments.
  An ISP (ISP) is an organization that provides access to the Internet.

• function of guard of source IP and dhcp DHCP scope of exhaustion (customer parodies other customers)

  Hello world.

  A dhcp server assigns ip address based on the mac address by equipment of the customer field in the dhcp packets.

  A potential attack is when a crowd of thugs mimics different mac addresses and causes the dhcp server to assign ip addresses until no ip address is left for legitimate host.

  For example, a host with mac1 h1 is designated by the ip address of the dhcp server as:

  199.199.199.1 mac1

  DHCP server has this entry in its database.

  Using hacking tools such as Yersinia or Gobbler can create a DHCP discover messages every time that create another mac for material scope of the client to the dhcp server, thereby causing a dhcp server to assign ip addresses because they are of legitimate dhcp to dhcp server discover messages with matching each another Mac in hardware of client addresses.

  You could use dhcp snooping and it will avoid that (exhaustion of dhcp scope) and configure the switch to check if the CBC mac fits the hardware address of the client in the dhcp message. But when even we can creat spoofed discover messages where mac src in the ethernet header will match the client hardware address in dhcp discovery message. It did not always overcome the problem.

  You might say use IP source guard characteristic but it really will prevent this problem from happening?

  Let me illustrate:

  H1 - f1/1SW - DHCP server

  Let's say that we have configured dhcp snooping on sw1 and f1/1 is untrusted port.  Switch a suite dhcp binding

  199.199.199.1 mac1 vlan1 f1/1

  Then, we configure source ip guard in order to validate the mac src and src ip against the dhcp bindings. When you configure keep source ip first, it will allow dhcp only if a host can request ip address and dhcp binding can be built. After that IP keep source will validate ip or mac src src or both against the binding.depending dhcp on how configure us source ip guard.

  In our case, we have configured source ip guard in order to validate the mac src and src ip against the dhcp binding.

  A dhcp connection is already created as:

  199.199.199.1 mac1 vlan 1 f1/1

  Now, using hacking tools Yersinia or Gobbler on h1, we create our first spoofed dhcp discovery message where mac src = mac2 ethernet header and client harware address = mac2 in dhcp discovery message. As the switch is configured with the function of guard of source ip and therefore allows dhcp discover message to pass through. DHCP server after you receive the message dhcp assigns another IP from the pool. The dhcp server has now after the entries:

  199.199.199.1 mac1

  199.199.199.2 mac2.

  We continue to spoofed dhcp to craft discover messages as described above and are dhcp server keep ip address assignment until exhausts the entire pool.

  So my question is how ip source guard in conjunction with dhcp snooping doesn't stop this attack does not happen? (IE DHCP scope exhaustion)

  I really appreciate your comments.

  Thank you and have a week.

  Hi Sara,.

  Ask was quite interesting. As far as I know that whatever it is port snooping untrusted won't let your fake dhcp server.

  You can take this query in the Sub forum of experts mentioned that is specific for dhcp snooping and source of guard.
