• How do I book DHCP on a WN203?

  I just started setting up my new WN203 to replace the part of a former ConnectionHub of Bell wireless. I got past the initial and assigned substance to a range of DHCP addresses to the new cluster of WN203, but I do not see how to associate a specific address to a particular wireless device.

  In case it isn't clear, let me give the example. When an address is assigned to a camera wireless AP, let's say his 192.168.2.220, I need to always get in the future so I can map this external address. In the ConnectionHub it's simple, there are two things to do. Assign the 220 to the MAC address and then put a new entry in a table of transfer from the port to say what external address matches. I think that the AP has reserve capacity, that I have not found, but port forwarding must take place at the router level.

  I didn't know how it worked, so I tried a number of things and this is what worked for me.

  I let the WN203 be a ConnectionHub upstream DHCP client and it has been assigned an IP address in the pool, which subsequently, I coded as a DHCP reservation. I turned on the WN203 of the DHCP service.

  When I used the WN203 network, my devices were assigned the same IP addresses by the ConnectionHub that he had used when its wireless feature worked. I was then able to use the same DHCP reservations as before which turned to simplify the whole process.

• Booking DHCP WAG120N

  Hello!

  I have a modem/router adsl wireless wag120n annex a. I used it for awhile. but I discovered that there not a DHCP Réservation feature. I updated its firmware 1.00.16 which is the latest version of the firmware. but I can't yet find a DHCP reservation.

  It's a place that I can't find? or should I download and install a software patch or plugin to have a DHCP reservation?

  Thanks in advance...

  Cisco only knows. Maybe they add it. Maybe not.

• Implemented DHCP in an existing network?

  I was in charge of implementing true DHCP in our existing network.  I say true DHCP because we currently have domain controllers redundant (Windows 2008 r2) allocation of IP addresses on a booking system where the MAC address of all the equipment had been seized and assigned an IP address.

  We are running out of addresses and we'll be adding more equipment to the network so I need to expand the range.
  The address range is 192.168.0.x - 192.168.3.x with a subnet mask of 255.255.252.0.
  We agreed to change the subnet a.248.x
  Two questions arise on that I am still quite inexperienced in this area:
  1 otherwise than to change the subnet on the servers, where can else I make this change?
  2. how to configure servers to assign addresses automatically without reservation?
  Advice, recommendations, references or are greatly appreciated.

• An error occurred while renewing interface wireless network connection: unable to contact your DHCP server. Request a expires.

  I use an Acer Asspire One with Windows XP. We have wireless through AT & T Uverse. The netbook has an Atheros AR5007EG Ethernet card.

  A number of things have taken place lately: I had not used the Acer for some time and the battery was dead and would not recharge. I could book until when it was plugged, but could not get on the Internet. I found online that the solution to the battery problem was to download a new bios that worked wonderfully and it is now loaded. Recently, our AT & T router died and was replaced. I put the new WEP keys in two other computers, and they connect to the Internet. I can't connect to the Internet with the Acer. I tried ipconfig / renew and get the error message: "an error occurred during renewal of the wireless network connection interface: unable to contact your DHCP server.» Request a expires. No operation can be performed on Local area connection while it has its media disconnected. "On the tab"Choose a wireless network", it shows my network and said"absorbing the network address"but nothing happens. When I do ipconfig I see that there is no IP address.
  I took the computer to Starbucks this morning, ran ipconfig / renew and she acquired the IP address and I was able to connect to the Internet. I brought the computer home and tried and failed to connect. The IP address is back to 0.0.0.0 and the error message appears when I try to renew it.
  I hesitate to make a lot of changes since it was working with a different network.
  Original title: IP address is missing
  These forums are wonderful. I tell myself that I've saved the cost of a new battery using the bios, I found on a forum!

• Cisco Connect Cloud and DHCP reservation

  Before updating my firmware on my EA2700, I can easily book IP address for my wired device. With the new interface of cloud, click to select the device in the upper back in the reserved intellectual property pane below. When I try to save the IP address change I get two errors: No 1) characters of the IP address invalid) 2 name. I get the same errors, even though I'm not edid not change the name or the IP address.

  In regard to the name of the device, I don't have not change anything or rename the device. A device has a '-' in the name and the router was happy with it until I tried to book the INVESTIGATION period. Another had a "'" in the name, same problem again.

  My Beach 192.168.1.200 to 192.168.1.250 DHCP network and I use the range of 192.168.1.1 to 192.168.100 for static IP address. When I tried to book a static IP address below 192.168.1.200, the router say that it is an invalid IP address.

  Workaround for this problem was temporary game DHCP vary to 192.168.1.1 to 192.168.1.50 and set the static IP address in this range and rename the devices that will accept the EA2700. Then I move the DHCP from 192.168.1.50 to 192.168.1.100 Beach and repeat the process. After all static IP are affected, so I reset the DHCP 192.168.1.200 to 192.168.1.250 beach.

  It is a pain to do. In the previous version (less cloud), it was a breeze to do. Also, I don't understand how to redirect ports with the new interface. Is - this progress?

  If the cloud gives you any new benefit, then perhaps you should consider coming back to the firmware that was simple and reliable.

• IP address? DHCP?

  Here in the United Kingdom, I want to connect using as WRT WRT ngn350 via a Modem, AM200, a necessity has no modem phone line. Through the books several times and failed to connect seems to be due to my bad setting of the IPs, and even features DHCP if neither manual mentions these issues arising from two separate devices.

  I don't understand that one device should use DHCP. Is this correct? If Yes, who is better to give this responsibility to? Further on this point, one of the devices wonder at the top of the page, if IP to be obtained automatically. I don't remember that Scripture which device. Get my addresses dynamically from the ISP, I wonder if the ref in the config of the said is internal within these two devices on my network.

  Both devices have default IP 192.168.1.1 address and clearly, it will not work so what address should I change and what it takes? Unless you advise me otherwise, I would like the router, WRT350N, stay like that and cottages on IPs but the router will not be the first device that would be a problem on the LAN?

  If you have other tips on configs for this arrangement say. I used to use combined devices and indeed bought the WRT by mistake because of the "vagueness" of the spots in this regard.

  The AM200 is router with built-in modem. This is the main problem. I recommend only to use a single router.

  Two recommended alternatives:

  1. set the AM200 in Bridge mode and use the WRT for your internet connection. The problem is, however, maybe that's not possible if your ISP uses PPPoA Protocol to connect to the internet. The WRT doesn't support PPPoA, only the AM200. I think that some providers of access to the use of U.K. PPPoA. If this is the case with your ISP then this alternative is no option for you. With the AM200 filled internet WRT handles all related functions. The WRT also distributes IP addresses in the local network through its DHCP server.

  2. use the AM200 as internet gateway/router/modem and use the WRT as ethernet switch and single access point. In this case, all functions related to the internet are on the AM200 only. The DHCP server is on the AM200. You will need to change the address LAN IP of 192.168.1.1 to 192.168.1.2 WRT and disable the DHCP server on the WRT. Then one of the WRT LAN ports connect to your AM200. Do not use the internet port on the WRT.

  There is a third alternative, but I recommend not to not use. Chaining routers is less then optimal and some experiences of people disconnects, instability and other probems with this type of installation:

  3. allow the AM200 as router on 192.168.1.1. Change the address LAN IP of the WRT from 192.168.1.1 to 192.168.2.1. Now connect the internet port of the WRT to the AM200. Now, you use two servers DHCP, one on the AM200 portion 192.168.1. * on the side of LAN of the AM200 which is also the side WAN/internet of the WRT (i.e. The WRT gets its internet IP address of the DHCP server on the AM200). The other DHCP server is the DHCP server on the WRT which now serves addresses 192.168.2 * to whatever it is connected wired or wireless to the WRT.

  Still, I do not recommend no. 3. You have chained two routers. First of all, everything is routed on the WRT then on the AM200 (or vice versa). Both routers are running NAT.

  I would recommend N1 if possible (that is, if you use PPPoA). If it is n ° 1 and n ° 2.

• Static route ISA570W to Comcast gateway/modem

  In my view, that it is a question of static route.

  I want to be able to connect to the gateway/Modem Comcast (10.1.10.1) using any computer on my network. Currently, I am unable to do this, I am also unable to ping the unit of Comcast. Here's my setup.

  Comcast device (SMC8014)

  WAN IP: 50.x.x.238

  LAN IP: 10.1.10.1 (255.255.255.0)

  A single cable CAT5E for:

  ISA570W (WAN Port) - (basic out-of-the-box configuration, 1 - WAN, DMZ - 1, 8 - LAN Ports)

  WAN STATIC Port info:

  IP WAN: 50.x.x.233 bridge (255.255.254.0): 50.x.x.238

  LAN IP: 10.1.10.2 (255.255.255.0)

  DHCP enabled for bridge VLAN-1 (10.1.10.30 - 99) by default: 10.1.10.2

  A single cable CAT5E for:

  Cisco SG200 - 50 p (POE switch to serve as a connection for phones and desktop computers)

  LAN IP: 10.1.10.3 (255.255.255.0)

  For devices on my network to get an IP address from the device of the ISA, ISA is also the default gateway. I have logged on to the device of Comcast and all firewall rules and blocking are disabled.

  Here's a copy of my current routing table according to the ISA570:

  Destination address	Subnet address	Entry door	Flags *.	Metric	Interface
  192.168.3.0	255.255.255.0	0.0.0.0	U	0	DMZ
  10.1.10.0	255.255.255.0	0.0.0.0	U	0	DEFAULT
  10.1.1.0	255.255.255.0	0.0.0.0	U	0	VOICE

  0.0.0.0	0.0.0.0	50.x.x.238	UG	0	WAN1

  My desktop (10.1.10.32), so I'm unable to ping or you connect the unit to comcast to 10.1.10.1.

  So according to me, that missing me something simple here, it is a solution of static route, or I'm looking for policies of NAT?

  Thanks for your help and please let me know if you need more information on my network.

  -Matthew-

  OK, a few possibilities here.

  1. Did you go through this process for the SMC8014 Bridge mode?
     • http://www.handymanhowto.com/2011/08/19/how-to-configure-a-Comcast-business-class-static-IP-address/
  2. I advise to use a different subnet on the LAN of the ISA to the 10.1.10.x interface.  The reason is that when you send a request from a subnet of 10.1.10.x behind the ISA to a subnet of 10.1.10.x, your PC and the ISA assumes that the device is on the same network and will not try to route.  Consider using the subnet of 192.168.75.x by default on ISA LAN interface.

  If you do not step 1 above, then I'm fairly certain that you will not be able to browse the internet at all.  If you can browse the internet, but just can't get the Comcast router 10.1.10.1, then chances are 1 step has already been completed.

• SRP527W setting DHCP address and source firewall rules

  In my quest to find a decent ADSL router for VoIP, I found the SRP527W and so far it has been the best performer of a range of boxes from netgear, thomson, and zyxel.  However, I have two questions:

  (1) how to troubleshoot DHCP leases on the LAN address

  (2) how to specify source ip in the firewall rule

  Note:

  I currently have 1 computer on the LAN, VLAN1 interface

  * 192.168.15.100

  and

  2 IP phones on the LAN, VLAN100 interface

  * 192.168.100.100

  * 192.168.100.101

  Address three assigned by the DHCP server lease times with approximately 20 days.

  I would like to repair the three devices DHCP leases, for example if some port forwarding rules can be made with confidence that the rules will not point to another device in the future.

  from PVC0-> 192.168.15.100, Port 3389 for remote desktop

  of PVC0-> 192.168.100.100 ex.port 5881 to int.port 80 for voip phone web-gui

  from PVC0-> 192.168.100.101 ex.port 5882 to int.port 80 for voip phone web-gui

  Ideally, I would like the rules to act like that, limiting myself only to access these ports (from my remote site)

  PVC0 interface where the source is ip 12.34.56.78-> 192.168.15.100, Port 3389 for remote desktop

  PVC0 interface where the source is ip 12.34.56.78-> 192.168.100.100 ex.port 5881 to int.port 80 for voip phone web-gui

  PVC0 interface where the source is ip 12.34.56.78-> 192.168.100.101 ex.port 5882 to int.port 80 for voip phone web-gui

  I hope that makes sense, I appreicate any help you can give.

  Kind regards

  Paul

  Hi Paul,.

  Thank you for using the Cisco support community.

  With regard to two questions:

  1. Yes - it is possible to configure static DHCP assignments.  Use the DHCP Server rule configuration page and click the 'Show DHCP booking' button to assign.

  2. Unfortunately, it is not possible to configure rules to address source for the SRP520 list.  (This is possible on the SRP540 for further reading).

  Kind regards

• RV180 Question DHCP

  Hello

  I swear to you that I had read somewhere that the RV180 only supported up to 50 clients DHCP before you had to book statically DHCP addresses assignments.  Is this true or am I confusing this with another router router?  Any ideas would be greatly appreciated.

  Kind regards

  James

  The size of the reserved DHCP addresses table is 50. RV180 is supposed to be able to support up to 253 clients dhcp.

• VPN 3020 - relay DHCP and reservations

  Hi all

  I have a VPN concentrator 3020 in my structure and I am setting up allocation of an IP address by an external DHCP server.

  There is no problem in that: the client authenticates and then receives its IP address...

  the problem is that I need to configure a reservation on the DHCP server... the question is: which is the mac address, use the booking?

  I saw on the server the mac address of the dhcp request is something like this 0003a08a5308020e7f28f4e9a82000, which is the mac address of the external interface of the vpn concentrator, as well as many other characters, which does not seem to be related to the client or any other part of the network and change each time we connect...

  I think that I can not assign the static IP address on the hub, or GBA, because users authenticate to the VPN through MS Active Directory hub, so that they do not really exist on these devices...

  Anyone know how I can do this job?

  Thank you very much

  Marco

  You can do that with the ip address of the DHCP server.

  You can configure the LDAP server to assign the individual ip address depending on whether the user authenticates to the access customer vpn.

  You must configure the LDAP server for permission in the VPN concentrator, but also to enable 'Use authentication server address' for the assignment of an ip address.

• Isolate the DHCP in vswitch

  Hi all

  I hope for some help that I spent the last 4 hours searching the Internet for an answer and does!

  I have a relatively simple ESXi installation which I use a development platform. I am currently only using a NETWORK card on the host server which is connected to a physical switch that uses the rest of the production for the company network.

  What I'm trying to do is to establish a network of simple test with three servers, a domain controller, another Member and an Exchange Server. The domain controller is configured to run DHCP by using the 192.168.1.x range. The domain controller has two network cards virtual, one linked to a vswitch which is connected to the switch of physics and the second NETWORK card that goes to a separate vswitch which other servers are connected to. The reason for DHCP is so that the technical team can create new VM machines with different operating systems and do not need to worry about configuring static IP addresses each time. The domain controller receives an IP address on the beach of 192.168.0.x network production network.

  A picture shows a thousand words, so here are the network config:

  

  The problem I have is that some devices on the production network to receive an IP address assigned to them from the DHCP server on the virtual rather than the DHCP computer in the production network. I'm running unauthorized DHCP server to stop what is happening but can't find a way to isolate the DHCP server so that it gives that IP address to the virtual machines connected to vSwitch1.

  Thank you very much

  Hello Rocco,

  Thanks for the help.

  I did a little research focused on the development of infrastructure rather then focusing on the aspect of VMware configurations and found Server2008 will broadcast packets on all DHCP assigned with a static IP public network adapters, even if it is only not on the links. However, when the NETWORK adapter is set to DHCP, then the server will not broadcast it.

  So what I ended up doing puts the NETWORK adapter for DHCP and then booking the IP address for the server so that it is always the same IP address for the production and the custom of DHCP server DHCP Server give it to someone else.

  I tried using dhcploc and it works perfectly.

  Thank you very much

  Scott
