| Dorms not allowing routers question
Supposedly if I connect a router to their network, they can detect it and shut me off.
Well, I've been running ICS off my laptop for quite sometime and I haven't been shut down yet.
So here's the question, are the routing methods in ICS different from a consumer level router? or are they just BSing me because they think i'll hook the router up backwards  |

| I have heard that the reason why routers aren't allowed is because in their default state they can cause an extreme amount of traffic and come close to crashing the network. However disabling certain settings that are needed for home networks can eliminate that problem, but obviously most people wouldn't do that. I don't know what that setting is though unfortunately. |

They just don't want you running DHCP off of the router...that's what they can detect because it'll screw with their network pretty severely. All you need to do is disable DHCP on your router, then have a network cable running from the port in your dorm room to the LAN side of the router, leaving the WAN port empty. |

You can use a router. It all depends on how your campus network is set up.
If you need to register your MAC address, logon through a web page, or do nothing but plug in then use the instructions below, if you need to use VPN software running on your computer then you can only us ICS.
All you need to do is clone your computers MAC address to your router.
Plug your routers WAN port to your wall outlet. Then plug your computers and game counsels into the LAN ports. Also you can leave your DHCP server on as it will not affect anything over the WAN port including your campus network. You might want to leave your firewall on in the router to help prevent any viruses or your campus IT guys from scanning anything behind your router.
Also when you connect your router to the campus network with the WAN port with your PCs cloned MAC address they will just think your PC is plugged in and they will have no idea you are using a router. |

St John'S, NL | Also when using a router remember to route the ports throught the router. Game consels and p2p will need ports routed, but you do not need to route any ports for just browsing the web. |

Please explain? Because to me what you said makes no sense whatsoever. If anything routers cause less traffic. Back in Fall of 2003 when those virii spread across the internet, college campuses were hit hard. All because they didn't have anyone turning on a firewall or using routers. If you have a routable IP address, not letting you use a router is reckless. |

DO NOT PLUG IN A ROUTER WITHOUT DISABLING DHCP!
It WILL respond to DHCPDISCOVERs from the WAN port. It WILL fsck up the dorm network, and you WILL get caught.\
Plug your WAN into the wall, plug your computers into LAN, and disable DHCP first thing. In fact, do it before plugging your router into the wall. |

The only time a router causes problems is when people plug the schools internet connection to one of the switch ports on the private lan side of the router instead of in the WAN port like they should. When I was in the dorms some idiot did that and my friends computer kept getting it's dhcp from that private router instead of the school and couldn't get on the internet as a result. Luckily it had the default password on it so we were able to turn the dhcp off. |

you can use DHCP fine. The routers DHCP will only attempt to assign addresses to the ports on the LAN side. IF you plug the schools network into the lan side it will attempt to answer DHCP requests and probably piss off your admin.
WHY do you want to use a router anyway? Just use a switch and you will be fine. |

| You cannot use a switch if your campus only gives you 1 ip address also if your campus requires mac authentication.
A router with your pc's mac address cloned to it will just look like your computer to your campus admin's thus allowing you to plug whatever you want into your lan side of the router and them not knowing its there. |

you CAN use a switch. a Switch is a Layer 2 device and only needs one IP address. The only "gotcha" with a switch would be the "mac address" IF the school requires it to be registered.

just turn off the WAN access and DMZ zones...make sure to buy a cheap router too. |

"You cannot use a switch if your campus only gives you 1 ip address also if your campus requires mac authentication"
buy a cisco switch and then make VLANS
most campus networks need to be at your computer to get your mac address, also in 2 seconds i can change what my mac address would look like to an outside source.
if it comes to and that dont work:
buy windows server
make your server a router and the problem is solved.
requirements:
2 NIC cards
1 connected to the campus
the other connected to a router/switch |

If the router is giving out 192.168.x.x addresses and the network uses 172.x.x.x addresses, you'll mess up the network with dhcp enabled because now you have 2 dhcp servers on the network both giving out completely different addresses to whatever client asks for one. If you turn off dhcp on the router, you effectively make the router a switch, and it will get the ip addresses from the school network and all will be right in the world. |

| and if you buy a router you can assign the IP address on both sides, just like you can assign the IP address of your NIC card on your computer even tho DHCP is enabled on the router as long as you assign a number that is within the given pool of addresses, which is not that hard to find out and do. dont argue with me on this you will lose. |

No... your "LAN" behind the router is a seperate network segment. Those computers don't 'see' the higher-level DHCP server.
...unless, of course, you're plugging the WAN and LAN ports into your campus network, which is stupid... |

I know this topic is old, but I want to clarify this.
So long as I have the router assign IP addresses within the given pool that the buildings DHCP server assigns, I will be good?
What if the router assigns an IP address that has already been taken by another machine connected to the main DHCP server? wouldnt that screw things up too?

| Basically, (to put this into simple terms) your router will look like a computer to the building's router/hub/switch. It will assign the router a IP address through its DHCP server. Now your router will have its own little network where your computers will connect to it. Your routers should come with its own little DHCP server that allows you to assign IP's for your own little network.
Sooooo... whenever your computers want to access the internet, it will route internet traffic through the single IP address assigned by the building's router/hub to reach the internet. Get it?
