City A is the data center with 2 WLC (CT2504-K9) and a number of AP. City B is a branch with MPLS between A and B. Right now the APs at City B has joined the controller. Users at B is getting ip's assigned from DHCP at City A. How do I configure the WLC so users can get ip's assigned from DHCP server present at B. Option 43 is enabled.
View 2 Replies View RelatedCurrently we're providing DHCP to wireless clients from a dhcp pool on a cisco 6500. Due to new requirements we need to move to windows 2008 dhcp and when I test this on an unused WLC (7.0.235.0) the client doesn't get an address.
When I do a packet capture on the client I see it requesting dhcp but not getting any response from the server. When I do a dhcp debug on the client I see the same (see attached file).
This seems to me to be a server issue but the same server is supplying addresses to wired clients.

View 10 Replies View RelatedI keep getting some additional IP addresses logging onto my home network that have an address outside what should be allowed by the router. The server is running at 192.168.2.1 and is set to only allow clients from 192.168.2.2 - 192.168.2.10 so a total of 9 clients should be allowed on.The problem is that something keeps logging in with an address of 192.168.169.2 or 3 etc. Sometimes more than one device at a time.I have assumed that it is some automated or virtual client as I'm pretty certain my network has not been breached. I have a 9 character password with a relatively random alphanumeric combination, although I haven't tried changing the password (I live in a share house with with a bunch of devices using wireless, so I haven't yet bothered). What I don't understand is how it has connected with the xx.xx.169.xx range at all. I have a Belkin 'Share' Wireless N Modem Router and at some stage there was a 'guest' network but that has since been disabled and I still am seeing the extra address. I have attached a screen shot of the DHCP client list on the router.The following is a list of devices that may be on the network at times, I'm thinking one of these may be responsible for the problem:
Windows Vista Desktop - Only LAN device
PS3
Macbook
Epson wireless printer
Android HTC Desire Mobile Phone
Laptops running various Windows versions (XP, Vista and 7)
A few thoughts I had:
- the android phone is capable of running a wireless hotspot, may have to look into it to see if if has been operating as an access point into the Belkin router, but assumed this wouldn't bring up clients connected to the phone on the home router.
- The desktop has PS3 Media server installed to stream video to the PS3 over the network (not that I have ever managed to get it to work), however this is not ever open on the desktop.
DHCP enabled with default settings. Dynamic IP range from 192.168.0.100 - 192.168.0.199.Router shows laptop with 192.168.0.199 however when I check the IP on laptop I have 192.168.100.10 and both laptops are connected on my SSID with 90% signal strenght.

View 1 Replies View RelatedIm facing with some DHCP lease issue and its like this,Our Cisco 2951 edge router is configured with local dhcp pool for a set of remote users when they connect through Cisco VPN which was working fine until we planned to change it to a Windows box that is configured for DHCP.The basic idea now is to relay the DHCP requests that are coming from the remote clients through Cisco VPN to the DHCP Windows server. So we added the scope on the server and changed the client config on the router as follows (highlighted is the dhcp relay config). [code]

View 3 Replies View RelatedI'm experimenting a strage issue with some AP1142 that prefer getting new IP from DHCP server rather than using the static ip already configured.
I've got more than a hundred of 1142 APs already conected to a 5508, all with static IP, all working fine for about a year.
As i installed 30 more AP, i enabled a dhcp scope on the controller to give IP to the new APs and when the new aps got registered i changed the configuration to static IP.
The problem comes when some of the older AP than have already static ip are gettig ip from dhcp scope.
If i look at my WCS, it reports that this APS are getting DHCP IP because they cannot reach the controller with their static ip. As this is impossible, because the static ip and the dhcp enable scope are in the same subnet in a layer 2 configuration and with the same gateway. (e.g: old AP 10.10.2.10/16; new AP(dhcp 10.10.3.10-50) 10.10.3.15/16; gw 10.10.254.1)
The problem comes when i disable the dhcp scope, all the older aps that got dchp ip from the wlc scope instead of using their staic configured ip are deregistered. If i reset every ap manually, from the swithc disabling PoE, they start to use the static ip and everything comes fine.
This is happening with about ten of fifteen APs from the 100 installed, that is the strange thing because this seem to be very random as the failing APs are installed in different building and connected to different switches.
As now i have disabled dhcp scope and all APs (old and new) have static ip everything is ok, but i will have to add some more APs shortly and every time i enable the dhcp scope on the wlc
Is there a way to get the E4200 to NOT provide itself as a dns server to the DHCP clients? I have the unit set up to provide two dns servers to the clients, but the 4200 always provides itself as a third and it uses my cable providers dns servers. I am using a dns based filtering service to prevent certain material from being accessed within my network as the first two resolvers. So long as both or one of the provided servers is working it doesn't fall back to the unfiltered third, but I would prefer to remove it entirely.

View 4 Replies View RelatedI have a few ASAs with L2Ls in a hub-and-spoke fashion, works great. All ASAs are 8.2(1). I've tried to add remote-vpn to the HQ ASA. I have this working on a PIX 6.3 box at HQ, but have not been able to make it work completely on the ASA.
Just to check, I also set up remote client vpn access on one of the spoke ASAs, and that actually did go well. Applying the equivalent config on the HQ ASA - won't function.
The problem with the HQ ASA remote client vpn is that after completed phase 1 & 2, the traffic goes one way only, from client side towards the ASA. I e remote side only encaps, no decaps; ASA side only decaps, no encaps. If the remote client pings a host on the inside (i e behind the HQ ASA) the packets arrive, and are returned towards the ASA (a correct route for the remote vpn network is in place on the inside host). However, it seems as if the ASA doesn't send that traffic back into the tunnel, but rather sends it unencrypted through the default route (doing a traceroute from the inside host for instance suggests this).
The ONLY way I can pass traffic towards the remote client is by initiating a ping from within the HQ ASA, it's the only time I get encaps on the ASA side and decaps on the remote side of the tunnel. Interestingly, it's actually the "ping outside 192.168..." that works, doing an "inside" ping fails. Compare this to the spoke ASA and its remote vpn client, there an inside ping is succesful, but not a outside ping, i e the spoke ASA functions as expected with its remote vpn. Given that the configs on the two ASAs are the same for remote client access, I would have expected both to work, not only one of them. But then, the HQ ASA has more lines of code, and I guess that something there gets in the way. [code]

View 4 Replies View RelatedI recently upgraded from a WRT54G and am having issues with a Win7 PC with wireless-N. Initially I had it configured static at 192.168.100.100 and everything worked, but the speeds were miserable (I followed all the forum posts and recommended settings). I noticed in the Status section of the router pages that the system showed up with the correct MAC address, but the IP showed as 192.168.100.10, which is the same as the router. Assuming this might be causing issues, I set a reservation for the system at .100 and set the client to use DHCP. However, now it won't pull an IP address at all. The status pages show the client with the correct MAC address, but an IP of 0.0.0.0. I've verified the MAC address a dozen times and rebooted the router and the client dozens of times with no change. Even when I removed the reservation, the system won't pick up an IP. I have a wireless-G client that's pulling an IP fine, so I know it's sort of working. The wired LAN is working fine, too. There are no IP conflicts, either. I changed DHCP to 'Always Broadcast (compatibility for some DHCP clients), but no change there, either. The client sees the network and still has a good signal, but just won't grab an IP.

I have a fresh install of LMS 4.0 on Windows Server 2008 Standart SP2. I have one NIC with static IP configuration. I also disabled DHCP client.The problem is follows: when I go to Inventory - Device Administration - Add/Import/Manage Devices, I always get this error:Error in communicating with DCR Server. DCR Server may be down. Please start the DCR Server and then refresh the page.Reload server/ Daemon Manager dont solve this.I try to beat this problem 2 days already. Second uninstall also doesnt solve the problem..
About a week ago I tried to clear log files which was 270gb (syslog.log) and after that restarted the server. And all inventory devices suddenly disappear! I could find it from search menu but cant access - cisco works said that there is no such a device in Device Repository or I havent enough right to view it (but i logged as admin). And after this i failed to add any device in Inventory. So I reinstall Cisco Works and get that DCR error..

View 2 Replies View RelatedAttempts to run remote desktop client a laptop on a tower using a CAT 5 Crossover isn't working. After starting the remote desktop on the laptop, I'm asked to identify the other computer, which I do, and a remote desktop window with a black background pops up, as expected. But I expect an opportunity to login will be displayed after a second or so. That never happens. After about a minute this pops up:Remote Desktop Disconnected?Your Remote Desktop session has ended.The connection to the remote computer was lost, possibly due to network connectivity problems. Try connecting to the remote computer again. If the problem continues, contact your network administrator or technical support.
My clients are impressed with my ability to setup their networks, Linksys routers with WIFI. But toss something unfamiliar into the mix, like this situation, and I'm pretty lost, pretty quick.
Environment:
Hospital's WIFI.
Laptop running XP Home with WIFI and Ethernet.
Tower running Win 7 Ultra with Ethernet.
Cat 5 crossover cable.
Goal:Configure laptop to access Hospital's WIFI. This is successful, I'm using it to post this. Configure laptop run a remote desktop with the tower as the server. The tower, running Win 7, has no monitor. I don't have a flat screen monitor, and didn't feel like dragging an 80 pound 24 inch Nokia into the hospital.After reading some sites while trying to figure this out, I gave the laptop the same group name, workgroup, as the tower.In my experience, starting the tower has been, turn it on, and it boots to Win 7. But I can't watch that happen without a monitor. I can't configure the the tower's network connections without a monitor either.I purchased the CAT 5 crossover cable yesterday, for this occasion. The label on the plastic bag it was packaged in had the word "Crossover" on it. I connect the CAT 5 to the laptop's single ethernet connection, and to the tower's Intel pro card. At home the laptop is on WIFI, the tower connects to the router.
I try to configure a simple EzVPN infrastructure:
EzVPN Server (CISCO2811, hostname cme) < -- > EzVPN Remote (ASA5505, hostname ezvpn-asa) < -- > Client
Attached you find both configuration of the EzVPN server and remote. The tunnel is getting up and if I ping from the ASA to the Router, I see the packets getting encrypted:
ezvpn-asa# ping 172.16.100.1
...
ezvpn-asa# show crypto ipsec sa
interface: outside
Crypto map tag: _vpnc_cm, seq num: 10, local addr: 172.16.100.2

If I connect a client with IP address 192.168.1.2 to the interface eth0/1 and do a ping to the cme, I don't see any packets getting encrypted. I don't have any idea about VPN, I just need it for a wireless lab environment. What do I have to configure on the ASA, so the inside traffic is encrypted?
After trying to configure remote client VPN access to a Cisco 2911 ISR using the CLI I tried to use the Cisco Configuration Professional. However, either way I have the same problem. A client can successfully connect and access servers but just once. When the client disconnects and tries to connect again there is no access to the servers even though the VPN tunnel appears to be up. I've tried multiple versions of the Cisco vpn client SW and all behave the same: 1st connection can access servers, subsequent connections can't. I've also tried a second (different) client after the original connection and still no luck. If I reload the router the client can get the vpn connection and access the servers but if the client disconnects from the vpn and tries again there is no access to the servers.
I've also tried it with and without NAT but it doesn't seem to make any difference.
The config generated using CCP is as follows:
version 15.0
