Toggle Via Hardware Device Between Two Lans
Sep 8, 2011
I need to connect my laptop that has a single wired network port to 2 different lans...currently I unplug the wire from wall port A and plug it into wall port B and back and forth. Is there something like a KVM switch, that can have wires from wall port A and B go in to with a single wire going out to the laptop's network card? Then I could just toggle a switch (push a button) to connect back and forth between the lan connected through wall port A and wall port B. Does such a device exist or would it make better sense to add another network card via USB and have both wall ports wired to the laptop all the time and use software to switch between each card?

I recently performed a system restore back to factory settings and downloaded updates to drivers for my service tag. I have a laptop - Inspiron 14R - and I'm having trouble getting my wireless key on the keyboard to work. How can I get it to toggle again. It seems now with the updated driver I have to manually connect and disconnect from wireless internet access.

I have two complete and separate "networks", each with their own internet connections. One is for home use, one is for business use.
(1) Home network has a D-Link cable-modem/router to the ISP. Variable public IP address. NAT'd.This router is configured "as provided" by the ISP (except for a few port-forwards). DHCP serving is enabled, etc. If possible, I do not wish to change any major router settings.LAN IP Range: 192.168.0.0/255.255.255.0
(2) Business network has a 2-Wire ADSL-modem/router to a different ISP. Static public IP address. NAT'd.DHCP serving is handled by a Windows 2003 Server. I am happy to change any router and server settings.LAN IP Range:192.168.254.0/255.255. 255.0
I have a network printer. It is currently connected to the Home Network (1) and has a static IP address 192.168.0.8, but I wish it to be accessible by PC's on both networks.My first thought is to simply connect both routers LAN-side via an ethernet cable. However, I can't find a way to add a LAN-LAN static route on the Business Network router (it only has options for WAN-LAN static routes). Do I really need to internetwork the routers via the internet?!?

I have 2 LANs in my own PC & 2 Routers (TP-Link WR941N each) with 2 internet accounts (512Kbps each) connected to the same ISP signal & company using NanoStation 5 from ubnt.As u know the connections work separately by default!! (I use Windows 7 64bit)Can I merge them to get double speed (download/upload simultaneously) using reg edit or special software or method?

I need to connect two LANs together with hardware VPN, for some file sharing. I was thinking to use a Linksys router and a dedicated ADSL line at each site, in order to setup the VPN. There is also an extra ADSL connection at each site for user internet access. how am I going to separate the two, without having to install two network cards on each user PC?If I set the user's gateway to the VPN or the internet router, how can I use the other?

My VDSL subscription will include both Internet, and TV. The supplied router then makes them available via two separate ports with different address ranges. LAN cables then connect to the computers and TV decoder from these ports.In the house there is a single Ethernet cable already running through the walls from the basement to the lounge on the ground floor. I want to consolidate both the Internet and TV data onto this cable and then split it apart again at the other side to go to a TV decoder and a wifi router.I don't want the VDSL router to be in the lounge as I will also have a TV decoder and Internet connection in the basement.I am renting the property so I can't run new cables through the walls etc.

I have my PC in my office with two lans,, one, the internal lan of my company with a static ip address, the other one a broadband line for connecting to internet.. If i switch on both the lans at the same time, i am able to use the broadband lan and the internal lan stops functioning,, to make it work i need to disable the lan with broadband line.. i even tried bridging the lans but that again stopped my internal lan. way to connect both the lans at the same time so that both the networks work simultaneously... and if there is any other option to function two lans on a single PC at the same time.

I have two locations in the same city and I want to connect them together so I can share files and printers. Each of the LANs has a router and is a simple workgroup. LAN A uses 192.168.1.1 255.255.255.0; LAN B is 192.168.2.1 255.255.255.0. What is the best way to connect these two networks together so I can share printers on both sides? Should I replace the network routers, they are older and definitely could use an upgrade

I have two LANs 192.168.0.* and 192.168.1.* (main)
I'd like to facilitate port forwarding on the sub-LAN - is there a way to configure the device to do so? The "main" LANs fowarding works just fine, however I have specific ports that need to go to the sub-LAN.

We live in a large ranch styled house. Conversely, we installed two broadband connection at opposite ends of the home. One cable and one DSL. Reason: Kids share DSL and Parents have the cable all to themselves. We are currently wanting to setup a media server where both networks would have access to a database of media files. It would be in the middle of the house and each network would connect to it wirelesslyI guess first off, is this possible

LAN L1, with IP addresses 192.168.10.x, for Company C1
LAN L2, with IP addresses 192.168.11.x, for Company C2
I have networks separated: different racks (but very closer fisically: a wire can be thrown), different gateways (to DSL), but both LAN's must connect with each other. I have acquired two RV042, one for each company to create VPN's (permitting telejob).

connecting to separate private lans:
A) 192.168.1.x
B) 192.168.0.x
A is behind a Watchguard XTM25 11.5.3
B is behind a CISCO SA520W
Both have static public facing IP's.
B only has a IP based PBX system attached to it over a SIP ALG. (originally it was hooked up to the watchguard but they didn't play nice, but works great with the Cisco. Problem is the Cisco don't have all the features of the Watchguard)
A has all my users workstations attached. The issue is that computers on A need to talk to server on B for a desktop application to work. Since they are on separate subnets, it isn't working. The app itself still doesn't work by port forward/sNats, etc.
A & B are right next to each other, so cabling between them is not an issue.
Currently, I have a cable between the watchguard and the Cisco. The watchguard end is configured with a static private ip on the subnet A (the cisco side), and plugged into the lan on the cisco side. I have a policies to let all traffic flow freeley, and from the logs on the Watchguard, all A subnet traffic is correctly going to the Cisco via said cable.
But, nothing is coming back from the Cisco. So my question is, how can I get the Cisco to play nice with the other subnet and send traffic back to the B subnet?

I have a Cisco 2600 with IOS 12.3. I need a very basic configuration to allow traffic between two LANs. To test this I cleared the router config to the factory default state and configured my network addresses on the interfaces.
When I connected a PC to each interface I found they could ping each other, I was expecting to have to write ACLs to permit the traffic into the interfaces, thinking that the default behaviour of the router would be to deny access. default bahaviour without any ACLs or other routing configurations?
My config, such as it is, is as follows:
Current configuration : 770 bytes
version 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption

I just got the E3200 and it's a pretty good router. Configured it to have 1 SSID as the 5Ghz SSID and the other as the 2.4 Ghz SSID. Since there are 2 SSIDs broadcasted, I was expecting machines connected to each distinct SSID to not be able to see each other, ie expecting the 5Ghz SSID to be a private LAN1 and the 2.4 Ghz SSID to be LAN2? It turns out machines on either SSID can see each other, so it looks like it on 1 big LAN even though there are 2 SSIDs.Doesn't a SSID map to a unique LAN even though they are in the same router?

We want to use a Cisco 861 Ethernet router to link our LAN's data and voice segments together (each on separate switches). Our switches are not Layer3 so routing over them is not an option. We only use the default VLAN1 on both switches.There is a data segment 192.168.1.0/24 and a voice segment 192.168.150.0/24, each with it's own internet/WAN access (internet for the data lan and SIP provider for the voice lan).
Diagram:
internet-~--router_192.168.1.1------192.168.1.0/24_data_lan--------192.168.1.254_cisco861_192.168.150.254-----192.168.150.0/24_voice------192.168.150.1_router--~-sip_provider
This is want i want to achieve:
- Link the data and voice switches using the 861
- I want to make the Cisco 861 the default gw on both segments, but they should only route traffic destined for the other segment to each other and route all other traffic to their segment's designated internet connection. I don't want the Cisco to do any NATting and there's no need for firewalling either.

My BEFSR81 is my primary router and has DHCP turned on. The router's DHCP range is set to accommodate 12 devices. I have three computers wired to it and their Host names (as specified in the set-up of each computer) show up in the router's DHCP device table. I also have two printers (one old Brother HL5250DN laser printer and one new HP Photosmart Premier C410a inkjet printer) connected and there are blanks where the Host name should go. I would like to be able to tell which printer is which when I am looking at the DHCP device table. How can I get a names associated with each printer's IP address in the router's DHCP device table? (The real problem is that the router seems to have both printers at the same IP address (192.168.1.100) and if I can get one of them to change I'd like to know which one it was!)

We are using LMS 3.2.1 with SP1 and Campus Manager 5.2.2.Server runs Windows 2003 R2.Everything runs fine except for User Tracking on two Catalyst 6500 switches running CatOS. These devices are discovered, reachable, SNMP works fine, neighbors seen. But when we try to launch acquisition, the UT utility complains with this error message:"Failed to start acquisition: Device unreachable. Please enter a valid device."When we wanted to add ports via Device Trap Configuration, LMS has fired a different error message: "There are no ports to configure for the selected device(s).Check whether you have selected any router(s)." I have checked the portsData.xml file, which doesn't have any ports included for the two devices: [code] We have tried to exclude / include the switches in the data collection, but that didn't work.

We're looking to deploy a certificate-based VPN solution for users with mobile devices (iPhone, iPad, and Android devices at minimum).We currently have CheckPoint firewalls (with VPN capabilities, currently unused), SonicWall, and Aventail devices at our disposal, but would not be against adding new equipment if the solution is secure, easy to deploy, and easy to manage.We want to use client certificates for authentication, though we currently have no infrastructure in place for such a thing.I'm looking for starting points/reference documents to learn to deploy:
* Certificate infrastructure, including a secure and manageable way to deploy certificates to devices, and revoke them if devices are lost or stolen.
* VPN concentrator configuration guides (whether it be Cisco or one of our existing VPN-capable devices).
