I have simple set-up in my network with 2 routers connected to each other, 2nd router is just kind of wireless access point and switch to extend cable sockets upstairs.I have DHCP reservation on the first router and it works perfectly. Second router has DHCP server disabled, and I have configured DHCP reservation same as the first router, but it gives random IP addressess instead of reserved. how can I configure second router to obtain MAC DHCP RESERVATION TABLE from the 1st router?

When I go to Status -> Local Network -> DHCP Client Table the list is blank but some computers are connected to the networkI'm using firmware 1.0.01 build 10 Feb 21, 2011, language = English, Firefox 4.0.1.Rebooting the router doesn't change anything, I can't see connected LAN equipment and DHCP Reservation is empty despite the fact I've created entries.Together with the "Access Restriction" which doesn't allow to block a computer from 10pm => 8am unless you create 2 rules + various issues with attached USB + 2.4Ghz signal that is far from optimal (never able to achieve more than 144-N-Mbps) and I ask myself if I will not contact the store where I purchased this unit and ask a refund (and buy something else from another brand...)
I tried to enter a name that included an illegal character (in this case, a single quote), and it gave me the popup box that said I had done so. When the popup closed, my DHCP reservation table was emptied out (I had maybe 5-6 reserved clients). In fact, I can't add new reservations anymore at all from this screen as it lists nothing in the DHCP clients table at the top. (Note, there are plenty of things in the DHCP Clients table over on the Status->Local Network tab). At this point, I think that my pre-existing reservations are still being held, but I'm not sure as it's only been about an hour so nothing has renewed.
I had firmware 1.0.05 when I encountered this problem. I upgraded to 1.0.07 as a means of trying to kick it into action, but the problem still exists.
my researvation table is incomplete. Below I show ipconfig that shows wired & wireless NICs assigned ip addresses by the E3200 router but the DHCP table only shows one.
I need to reserve the ip address of the wired address but can't get at it.
I have Linksys E3000 Router and it is connected to 7 Devices at this moment via DHCP. I have got New NAS Enclousre (8th Device) which has got Lan port . I have connected Box to One free Port on E3000 Router. I see DHCP Reservation from 192.168.0.1 assging one IP to My NAS Enclosure Box i.e 192.168.0.13 But when i ping that box . It's not pingable. When i try to browse that NAS Enclosure's setup web page - it's not opening. I can access that box setup page if i connect direct 1:1 Lan cable over private network (169.254.XXX). It means web server is runing on box. I am clueless. E3000 is assigning IP to NAS Enclosure but can't Browse or Ping. I tried to Assign Manual IP address to NAS enclusure and reconnect to router. Still I can't ping or browse.
#arp -a show that box has IP. (Output from MAC os) .

Before upgrading my firmware on my EA2700, I can easily reserve IP address for my wired device. With the new cloud interface, I click to select the device from the top pane to bring it down in the reserved IP pane below. When I try to save the IP change I get two errors: 1) Invalid characters in the device name 2) Invalid IP address. I get the same errors even if I do not edid not edit the name or IP address.
As for the device name, I did not change anything or rename the device. One device has a " - " in the name and the router was happy with it until I tried to reserve the IP. Another one had a " ' " in the name, same problem again.
My network DHCP range is set to 192.168.1.200 to 192.168.1.250 and I use the range from 192.168.1.1 to 192.168.100 for static IP. When I tried to reserve a static IP below 192.168.1.200, the router say that is an invalid IP.
The workaround to this problem has been to temporary set the DHCP range to 192.168.1.1 to 192.168.1.50 and set the static IP in that range and rename the devices to a name that the EA2700 will accept. Next I move the DHCP range from 192.168.1.50 to 192.168.1.100 and repeat the process. After, all the static IP are assigned, then I can reset the DHCP range to 192.168.1.200 to 192.168.1.250.
This is a pain to do. In the previous (cloud less) version, this was a breeze to do. Also, I have not figured out how to redirect ports with the new interface. Is that progress?
i am having an annoying issue with my wrt400n and my foscam FI8918W. in the dhcp reservation tab, the wrt400n doesn't show the foscam anywhere in the tab. it shows all laptops, cell phones, nases, etc. if i use the cisco connect software it does show it in the network map. i can probably add it manually via the gui. is this something normal or security cams not considered devices?

Router says "Invalid IP address" when I try to make a manual IP address reservation of the IP address range.
Example: local network 192.168.1.0/24, where .1 is a router, .2 is a reservation, .20-.50 is a range for DHCP.
Before upgrade I didn't have this problem.
I have the e4200 and I am having trouble getting DHCP reservation to work properly with my Windows 7 machines. Perhaps there is a step that I am missing. Basically I go to the DHCP reservation setup page, select my machine and add it to the reservation table. Then I save the changes. As soon as I do this my computer goes offline. If I reboot my machine, it is still offline. I've tried the same procedure to reserve the IP address for my phone and it works fine so I wonder if the problem is with Win7.

View 1 Replies View RelatedEver since I updated my firmware to 1.01 my web interface for the network settings screen has been random. Somtimes it shows a DHCP reservation list, sometimes it doesn't. Sometimes there are reservations, sometimes there are selectable radio buttons. I guess I'm just trying to figure out if this is a firmware issue or not. Ever since I updated the firmware it has been flakey.... But I was having issues with other stuff before that. When there are no reservations, sometimes i can't even select any computers because there aren't any in the drop down, when all of my hardware is online?
View 6 Replies View RelatedAll the SOHO routers I have used had a table which shows IP, MAC, Name, etc. In this table, I could easily put a check mark to a check box in a row that I would like to bind/reserve and IP would be reserved for that specific MAC.
In ISA570W, when I need to reserve/bind an IP to a MAC it asks me to fill out a table in which I have to manually type in the name, IP, and MAC.
Is there an easier way?Is there a way to do the reservation for multiple clients at once?If this is the only way, do I need to copy the mac address of each client somewhere and then reserve IPs for each one manually? This method looks very far from user friendly and efficient, unless there is a very logical reason that I cannot think of.
I've just got a WAG120N router and can't see anyway to see what devices are attached to the router or be able to assign static IP's

Have a client wanting to hand out public ip addresses to all clients from a PFSense Firewall terminating the internet connection.
How do I allow the Cisco Switches currently in place, configured with private ip addresses in the 10.10.x.x ranges and Vlans, where the main 3550 layer 3 has defined dhcp scopes for each vlan, to relay dhcp requests from all vlans to the PFSense firewall?
I assume I would take off the currently defined dhcp scopes for the vlans and configure each vlan/switch with the ip helper address and specify the PFSense firewall and that Nat would have to be disabled onthe firewall?
Two people went on a business trip with their laptop and when they came back they could no longer access the data server. Cannot map the network drive either.
1. Every desktop PC in office can see and access the data server fine.
2. We have a DHCP and DNS server (on one PC; Windows Server 2008), but we had to shut down the services because internet and email didn't work when the DHCP and DNS server service was on. I am confident that this is due to the recent shutdown of the company e-mail server (now outsourced) and the server settings needs to be reconfigured. The described symptom persists even when the DNS server service is stopped.
3. Upon taking a closer look at the DHCP reservation settings. The reservation status indicates as "Reservation (inactive)". I don't know the MAC address of the device, so I have no idea if the values are correct. Tried rebooting the server, delete and recreate the reservation, reboot router; no cigar.
4. Using the coworker's laptop, the data server is shown in the "Other devices" section even with the DHCP sever disabled, but shows error that it cannot access it.
5. All users, with the exception of the data server, have dynamic IPs assigned.
6. DHCP, DNS server is set to 10.10.10.2, Router is set to 10.10.1, Data server is set to 10.10.10.175. 10.10.10.2 is also an accounting server which can be accessed by everyone even in the midst of this mess.

View 1 Replies View RelatedI made a reservation then cancelled it online, but Sheraton Dallas Hotel charged my MC for one night for "No show ". Because they did not send me e-mail confirmation for both reservation and cancellation, I have no way to prove my cancellation. In e-mail they said:
"At the time you booked your reservation online you did not have your email address noted"
I have been traveling for the past 10 years and reserved Hotels online, and I never forgot to give my e-mail address not even once, so how could they said that I forgot this time ? I believe in keeping expenses low, if I don't give my e-mail address, I may end up paying expensive long distance call to communicate, as many hotels have no toll free numbers for dispute solving, so it's impossible that I forgot to gave my e-mail address! Unless someone manually erased my e-mail address for unknown reason. This I see as indication that a computer system error existed at that time What do you advice me to do to solve this problem ? Maybe computer system record ? In that case what particular system file I should ask them to mailed to me. Is there any way I can spot if there was any tampering? Like erased my e-mail entry, erased cancellation request?

I've just set up an old netbook as a secure ftp server on my network. As part of the process I locked the server host IP by making the lease permanent in the DHCP/Address Reservation page of the routers web GUI.However I later noticed the MAC binding page which seems to achieve the same thing (lock an IP address to a specific adapter). I was wondering what the practical differences between the two techniques are? i.e is it better to use binding than reservation?
I have the gut feeling that binding is more robust as I'm not sure what happens to a reservation if the specified host device is removed and then the router rebooted, is the address released back to the pool of available addresses? Binding feels like that address will never be made available to another device even if that device is no longer present, or is that completely wrong?Also does the binding survive a router reboot?

I have a Cisco ASA 5500 as the main router with a DIR-655 as a wireless access point behind it. DHCP is turned off on the 655 as the ASA is providing DHCP. This worked great for about a year and now suddenly, without any changes, I'm having problems. The only thing that connects without a problem is a laptop, which shows up on the device list with an IP. Other devices have problems. iPhones connect, show an IP on the device itself, but when listed in the connected list on the 655 show no IP. The connection is super slow. An Airport Express will connect, but again, shows no IP in the connected list on the 655. Using the ethernet cable from the Airport Express, nothing can get an IP. I can live with the iPhone not connecting, but the Airport Express not connecting is a major problem. Any reason why this would just stop working one day?
