Multiple Devices With The Same IP?
Feb 7, 2011
I am in a manufacturing test scenario and need to connect multiple devices with the same IP address (identical hardware all with the same fixed IP) to one Windows 7 desktop for the purposes of testing.I have a 3Com SuperStack II Switch 1100 that I am using as my switch. This switch supports VLAN and I have set up a number of VLANs, 1 for each device, with the host machine residing in all of the VLANs. I need to connect to these devices via SSH, preferably all simultaneously.'m thinking this will work except I have no idea how to differentiate ssh traffic to/from any 1 of the VLANs to the host.

I would like to connect a variety of wireless devices in my house to my work VPN while allowing other devices in the house access to my home network as normal.I was hoping to find a wireless ADSL router that allows me to associate a LAN port to a VPN connection, then connect a wireless access point to that port. I could then run two wireless networks in my house, one that would connect to my work VPN and the other that would not.

I lost it on my old laptop. Figured it was time to get a new computer anyways, we bought a new one, along with a Playbook. Both the new computer and the Playbook have had this problem, though they were able to fix it.They all use Wi-Fi.

I want to connect my ps3, sky hd+ box and samsung smart tv. Upstairs is my wireless router and I have connected to this by using a power supply networking adaptor (duvelo). I have since purchased a cheap ethernet switch from ebay and plugged this into the power adaptor connection next to my ps3, sky hd+ and samsung smart tv downstairs. I thought by connecting these 3 devices to the switch (which is connected to the duvelo adaptor) I could have all 3 devices simultaneously connected online. However, I still can only have 1 ethernet cable in the switch at once and hence only connect 1 device at a time.

We can only connect 2 devices at a time. Someone suggested that it may be a setting with my wireless router.

I just got a Nook Color as a gift (nice huh?) I just bought my iPad2 in Jan. So now I've got Comcast cable with a Netgear N600 router and:
1 desktop Win XP sp3 plugged into router
1 desktop Win 7 usb wireless
1 HP laptop w/ Vista
2 Dell old laptops Win XP not used much
Sony PS3 not on much
iPad2 always on
Nook Color
AND a Roku always on
I think that's all. So I'm guessing all this will slow down my whole connection? My iPad is the fastest. My Nook is extremely slow. Maybe it's the B&N website? When I go to shop and even when I registered it, it says connection having trouble. I finally had to setup my account at BN with my desktop. The Nook wouldn't stay connected.

I work from home and host quite a few machines within my home network which are all accessible internally, however I have a requirement to be able to access multiple services externally.I have standard home broadband with a SKY ADSL Router Modem and have the ability to set a DMZ, however i can only put 1 IP address as the DMZ destination. This means that from externaly, I can only access a single machine, obviously I can RDP from there but I need other services, for example SSH to another machine. Anything that I can buy which I can set as my DMZ, but can have rules which will redirect me once in the internal network to different services?

I have a wireless G router and all of my devices that connect to it right now all have wireless adapters. I have several devices in a media closet (about 3 or 4 - Blu ray, DVR, ect) that only have wired ports. Since all these devices are right next to each other, I don't need to buy a wireless adapter for each one because that's just pointless. is there a way to have all 4 of these wired devices connect to a central device, which in turn this device connects to my wireless network? I know there is a way I just haven't been able to figure it out.And then, with this new device, is there some special way it has to be configured?

I just moved into a new place and the cable company supplied me with a Motorola sbg6580 gateway and I have a netgear wnr3500l router with dd-wrt. because of location I have computers plugged into both devices (htpc and game consoles in the gateway, desktops in the netgear). how would i configure the gateway and router so everything sits on a single network AND the netgear with dd-wrt handling all the heavy lifting (port forwarding mostly)

The original network had a Zylex router, Netgear Switch. There was 2 pc's, one XP and Win 7. There is also 3 tills connected too. There is VPN network connected too. This emits a wireless signal to connect to a scanning gun and is also used to administrate the entire network. I was told by the Administrator of that network that it shouldn't interfere with the wifi network.
The job I was requested to do was to install 3 new wall plates as the Win 7 pc was using a Belkin wireless adapter. There was 2 put inside the office where the XP and Win7 pc's are located. The 3rd was just outside the office.
Now all the ethernet connections work 100%. The wifi is another story though. It will show up in the connect too, when you try connect it will disappear/no response from AP/connect then disappear, these are random too. No order to when each is error is displayed. Even when I put in another router the exact same issues happen.
I have tried to connect to both routers wifi when it wasn't plugged into the switch. Just the router's turned on with no cables plugged in separately of course, no joy same issue with both.

I just bought the E3200 and have it all set up and have been able to successfully print from the USB port. I want to know if you can use a USB hub to connect multiple devices to the router. I found a couple of similar questions on the forum, but they're all back in 2011 before the 1.4 update to Cisco Connect.

I got the new EA6500. For the last few days I've noticed there are multiple devices showing under one device with different IP addresses. In the beginning they show up individually with their own device names, then somehow combine. Each device is different ie. computer, phone, DirecTV box, etc. I did a hard reset, re-flash and still it keeps happening.

I have a Linksys Wireless-G WRT54GS with SpeedBooster.When I turn on 3 devices on Wi-Fi ( for instance 2 Apple MAC Computers, 1 Windows PC, and a wi-fi printer ), in other words 3 to 4 devices, everything works fine. BUT when I add another device later in the day ( lets say an iPad ), the iPad is not able to access the wi-fi connection. I get a message saying that another device is already using the connection.If I reset the router, then the iPad will be able to get in along with 2 or 3 other devices. If I try an extra device, I get the same problem.What can be causing this? I was under the impression that the router can handle an unlimited amount of wi-fi devices.

We have got a pair of N5K and 4 N2k. So far, we have configured VPC Keepalive (2x10G) & VPN Peer (1x1G) between N5K. Also we have configured one N2K with Dual Hommed VPC with both N5K.Now I am having some difficulties with desining/configuring EIGRP with Upstream routers/L3 65xxVSS switch.
Here are the queries.
1) Do I have to create another 1GE link between these 2 N5K to enable routing in between.
2) For these 2xN5K should I enable Eigrp on physical Interface or should I create VLAN & VRF to enable routing in between.
3) For N5K to Upstream L3 device should I have to configure EIGRP on physical Interface or should I create VLAN & VRF to proceed. We have 2 uplink each to connect to 2 DC and we are not planning to aggregate 2 links (VPC or L3 Ether Channel) for each site.

Has come across issues with multiple GRE tunnels between two devices when using the same source and destination addresses. I've tried using tunnel keys but this makes no difference. The only way I can get this to work is between different source & destination addresses.

We have a Cisco 887 router and a Cisco SG-200 switch.We'd like to setup trunking between these 2 devices for multiple VLANs on the switch to be made available on the router.
With previous routers, you could set the router up in the configuration 'router-on-a-stick' and VLANs worked like a charm but the 887 no longer support sub-interfaces.So how can you get trunking working between the 2 devices?
Is there a VTP configuration menu for the SG-200 which we can setup in order for it to talk 'VTP' with the 887 router??

My PC will connect just fine, but it is the only device on my network that the router will allow internet access. The router will allow other devices (DVR, laptop, nook) to connect to it, but won't allow those devices to connect to the internet. Each device will show the same error, - "connected to linksys - no internet". I've reset the router many times with no results.

Once your devices start showing up in your device list make a DHCP reservation for each device. (after confirming that no other devices are listed under it).
If you have a device that has multiple MAC & ip addresses under it you MUST first determine what the devices are listed & power-down before you can delete the device. Also note that some wired devices will still show as connected so you must have to either power down the device by pulling Th power cord OR disconnect the ethernet cable.

I have installed my new E4200 and it works beautifully. I have several wirelss adapters and a few wired connections through powerline adapters. I also have a second VPN router attached to the 4200.I can see the wireless connected devices with the associated IP addresses. If I plug a laptop directly into the Cisco, I can of course see it.However, I can see none of the devices attatched to the powerline devices? I have a securty cam connected via the powerline and want to know the IP address. I checked with cisco technical support via chat and they said it is impossible. I have used 2 previous routers with the same configuration and can see all devices.

Currently my home network is being switched via TrendNet TEGs80G unmanaged gig switches. I have been using them for about a year now with no issues. As my home network becomes more advanced, I recently just added a Cisco ASA5505, I am thinking about swapping those unmanaged devices, 4 of them, to managed. I was looking at the Cisco SG300-10 for upstairs, and a 16 port variant for my main core. These devices do not support full Cisco IOS cli, but they are manageable with a rich feature set nonetheless. My question is, should I swap the unmanaged devices with the more expensive Cisco devices, or just keep what works and save the money until I really need to spend it. As previously stated, my home LAN works just fine as it is, however my WiFi, NTV550s, server and workstations are all on the same network. Probably not the most secure but it is what it is without VLAN support.

All of a sudden my laptop, android phone and blu ray player (all wireless devices) can't communicate with my wired devices (marantz receiver and samsung tv). Everything still connects to the internet independently but i can't for instance play music from my wireless laptop to my wired marantz receiver. I had no trouble with this last week and didn't change anything (that I'm aware of) I did get Verizon to switch out my router but it didn't solve anything. My wife's computer also cannot connect to wired devices. Lastly, if I connect my laptop with via ethernet cable it sees wired devices fine. I tried shutting off windows firewall but didn't work. I have no other firewall/virus software installed. I can ping to all devices (wired and wireless) from my laptop.

how i can configure a second ssid for guest access in our environment. this is our network setup prior to this request: Internet----Firewall (not ASA)---ce520---C1131AG and CME router is also connecting to the ce520 switch. we only have two vlans: one for voice and two for data.
Presently, there is no vlan configured on the AP because it on broadcasting ont ssid and wireless users gets IP from a windows DHCP server on the LAN. the configuration on the ce520 switch port for the AP and other switches say access vlan is the DATA vlan which automatically becomes the native vlan for all trunk port connecting the AP and other Stiches to the network.
Now with this new requirement, i have made my research and i have configured the AP to broadcast both the production and the guest Vlans. The two vlans are 20-DATA and 60-Guest. I made the DATA vlan on the AP the native vlan since the poe switch is using the DATA vlan as native on the trunk ports. I configured the firewall to serve as DHCP server for the guest ssid and i have added the ip helper-address on the guest vlan interface on all switches while the windows server remains the dhcp server for the production DATA Vlan. I have confirmed that the AP, switches can ping the default gateway of the guest dhcp server which is another interface on the firewall. I can now see and connect to all broadcasted ssids but the problem is I am not getting IP addresses from both the production dhcp server and guest dhcp server when i connected to the ssid one at a time. My AP config is attached below.
Do i need to redesign the whole network to have a native vlan other nthan the data vlan? Does the access point need to be aware of the voice vlan? Do the native Vlan on the AP need to be in Bridge-group 1 or can i leave it in bridge-group 20?

I am trying to build a new network from scratch, I have the WLC 5508 w/ Aironet 3600e APs connected to my Netgear Smart Switches and a Linksys RV082 router that I'm using as my DHCP server with several VLANs for several stuff on my Switches.
I have 2 questions:
1. Can I have 5 Interfaces configured on 5 different VLANs, each SSID on each a different Port:
Port 1: Controller management only=> 192.168.x.x /24
Port 2: SSID 1: WiFi Internal=> 172.16.x.x/12 (Radius Auth with no sharing)
Port 3: SSID 2: WiFi Internal w/ sharing=> 192.168.x.x/24 (Radius Auth with sharing)
Port 4 :SSID 3: WiFi Guest=> 10.0.x.x/8 (Web Auth)
Port 5: SSID 4: WiFi IT=> 192.168.x.x/24 ( Radius or certificate Auth with access to the controller management interface)
2. How can I use the Controller as the DHCP server for all the WiFi traffic, and how should that be configured to work with my other DHCP server?

i`m facing a problem configuring the mentioned access point to act as stand alone access point with multiple SSID assigned to differnet VLANs the problem is that
1) i`m not able to broadcast the both SSIDs in the same time from the Access point
2) i need to make the radius server to manage the SSID access for the wireless clients (trying to find a way in which the aceess point sends a log for the radius server containing the VLAN id /IP address of the the SSID) you may find the below info about the IOS ver. & the configuration?
i`m running IOS /c1100-k9w7-mx.123-8.JEE/c1100-k9w7-mx.123-8.JEE?
