How do I connect 4 systems to the internet while hiding 3 systems?

Connect a router to your ISP, then connect your computers to the router.  The router will get an IP address from your ISP.  Set your computers to get their IP address via DHCP (Dynamic Host Configuration Protocol) from the router.  The router will assign non-routable IP addresses to your computers, therefore they cannot be seen on the ISP side of the router.\n\nThe router uses NAT, network address translation, to map packets to and from the ISP to the correct computer on your LAN.\n\nThis is a very standard setup.

get a 5 port 10/100/1000 gigabit NIC\njust so you can be leet and suck up all your LANs bandwidth

Get a switch and hook it to one of the LAN ports on the router.  Connect computers 4 & 5 to the switch.

There is a solution to do this that will work without using a hub/switch. It's really kind of easy and not too hard to set up.\n\nTHE HARDWARE - \n\n3 PCI 10/100 NICs\nI reccommend Linksys cards. They tend to work the best in my experience. 3Com are nice to have, but tend to run a little spendier. \nSome computers will have the ports you need built in. Look on the back of your computer. You should see some ports that look like phone jacks. You can distinguish a phone jack from a network jack by the number of gold pins that are in the center of the jack. If there are four pins, thats a telephone line (RJ-11). Eight Pins signifies a network jack (RJ-45).\n\nYou will also need a Cat5 Crossover Cable. If you don't have one or you don't know what I'm talking about, go to your local Best Buy, Radio Shack, WalMart etc and try to find one in the computer section. Its very important that it says CROSSOVER. \n\nSOFTWARE-\n\nWindows XP. Thats it.\n\nTHE SETUP-\n\n1) Install the network cards so that one machine has two network ports in it and one machine has only one. \n\n2) Install any drivers that came with the NICs. \n\n3) Hook up the cable modem / dsl modem so that the network port on the modem connects to one of the network ports on the machine that has two network ports.\n\n4) Connect the crossover cables between the open network port on the computer with two network ports and the computer that has only one network port.\n\n5) On the computer connected to the modem, set up Internet Connection Sharing. (For tips on how to do this, visit Microsofts website <a href=http://www.microsoft.com>here</a>.\n\nThat's It! Enjoy the internet on two seperate computers.

If you only want to link the computers to each other, install NIC's in each machine, and connect them using a crossover ethernet cable.\n\nIf you want to network the computers and share an internet connection, the method will be determined by whether you have dial-up or a high speed (DSL or cable) connection.  You don't give enough information to point you in the right direction.

Safe mode with networking

Going by your network diagram, i think your best bet is to remove router 1 from the network and connect router 2 directly to the modem. That removes the ambiguity of having two router cascaded in a home network like yours. Doing this, all computers can be on the same network and sharing files becomes easy,\n\nAnother option you have is to yuse a wireless bridge instead of router 2. This again ensures all computers are on the same network.\n\nA third but more intensive option you might sonsider is setting up a vpn within your network which enables you to do such files transfers. Some programs are also available which can help with this. e.g Microsoft Netmeeting\n\nIf you donot want to change your network structure in anyway, I'll advise you go for this last option.

My method of safety is to buy more then 3 hardware firewalls.\n\nYou can buy a hardware firewall cheap by buying the cheapest local area network router (Belkin, Linksys, etc etc.). Why do more then 3 help.\n\nWell lets explain this. Different routers could have different vulnerabilities and 3 would be like this:\n\nB stands for Backdoor\n\n    Hacker\n******|\n******|\n******|\n******V\n.....|B|.......\n******V\n..|B|..........\n    Splat\n.........|B|...\n\nIt would make it more difficult for a hacker to attack you.\n\nAlso get a anti-virus, and anti spy-ware. Another tip is to have encryption (For data, and connections). I recommend you get a anti-virus too.\nOh teal also you should download all Service Packs, hot-fixes, patches, and get a software firewall too.\nOne more thing is to rename your administrator account.\n\nTo learn more goto http://www.markusjansson.net/exp.html if you use windows XP, or 2000.

Use a hardware firewall with NAT and all ports stealthed. Make sure UPnP is disabled, and only allow outgoing connections to trusted (non-proxy) sites.

You would need 2 NIC's in each machine.   \n\nbox 1\nNIC A- 10.10.1.1 (main GW to internet)\nNIC B- 192.168.1.1 (Set DNS to NIC A)\n\nbox 2\nNIC C- 192.168.1.2\nNIC D- 199.100.1.1 (Set DNS to NIC C)\n\nbox 3\nNIC E- 199.101.1.2\nNIC F- 202.100.1.1 (Set DNS to NIC E)

You can't do that with a SOHO class router.  You can do that with something beefier.  On the cheap, I'd strongly recommend IPCop, a free, open-source firewall system that runs on a spare PC with two NICs.  There are add-ons such as Dansguardian that you can use to limit internet access as well as others that will block outbound traffic by port, IP address, or MAC address.  Go to http://www.ipcop.org for more information.

broadband modem with Wi-Fi router and plug in USB WiFi adapter under £40 from www.dabs.com.\n\nplug in the broadband router and modem in to the room were the phone line is. then plug the USB stick (once you have installed the driver software) into the second PC.\n\nset up the Wi-Fi security and the firewall to block all other devices that you dont own by Filtering which devices you want to allow access to your network set up the MAC address of all the Wi-Fi devices in the filter.\n\nyou can have upto Four computers connected VIA cable to the router with additional Wi-Fi connectors.\n\nhave one pc in the same room as the phone line and direct connect (cable) it to the router. if you dont do this you will need an aditional Wi-Fi adapter for the other computers on your home network.\n\nthe reason for filtering the devices on your network is simply so that you don't end up being kicked off your OWN network by unauthorised access. you should also block the router from broadcasting it's signal.\n\nand all firewalls should block in and outgoing ICMPand ICMPv6

If you changed the default admin password on the router and enabled encryption, thats a good start.\n\nYou could also set the router to only accept signals from your system by specifiying the MAC address of your NIC

what OS (operating system) are you using what type of internet connection and what firewall

1. get a switch\n2. get some straight UTP cables (as many as the computers you want to have in your network). The cables can be up to 100 meters long. \n3. make sure all your computers have network cards\n4. connect the computers to the switch using the cables\n5. power the switch\n6. configure the ip addressess your computers. Use 192.168.1.1 for the first computer, 192.168.1.2 for the second and so on. configure the subnet masks as 255.255.255.0\n7. Make sure all your computers are in the same workgroup.\n8. have fun sharing :D

I'm not sure but my answer is 3 Metro Ethernet

1.Don’t think you can which is why we use hardware VPNS but I think I saw some cisco software that would allow multi vpns A better way of doing it is to daisy chain your VPNS together under different ip ranges \n\n2.Not to sure but I would think that limitations to ip rages are standard they are in 2003 server another way of looking at it is to lock down via subnet mask? \n\n3.I usually charge!
