Re: Dorms not allowing routers question
If you plug the ethernet from your dorm into the Wan/Internet port on your router, then your network devices into the 1-4 switch ports, you will be fine. A DHCP server is fine because it will only assign IP address within the LAN, the devices within the 1-4 port switch. The router does not do a backwards DHCP, no DHCP assighnments come out of your routers wan/Internet Port.
If you were to plug the ethernet cable that is supposed to go into the Wan port into a switch port, then it will start assigning 192.168.x.x IP address to other nodes.
A router is fine, But an Admin can see that you are using a Linksys router, This is due to the name of the node being Linksys. |

If someone is a dumbass and leaves the DHCP server on, and plugs the network cable into a LAN port, instead of WAN, it will cause havoc. The router would start giving out IPs to other machines. Definitely not good.
As long as you plug the cable from the wall into the WAN port and clone the WAN MAC address, if your resnet auths based on MAC, you should be fine. The only issue that will arise is the router's NAT/firewall killing any filesharing abilities with outside networks.

They said they didnt really care about how many devices were on the network (they even offered to setup QoS for me for free in the event I got a VoIP device)

ResNet probably doesn't want you to install routers/switches/hubs cause that means introducing more computers (i.e. more bandwidth... which translates into cost for them ). If you are installing a router/hub (which is a common thing), you should not have a problem.
The earlier statement about it not working on a campus network is without merit (as you can see -- no one backed up his claim). Happy surfing!

I talked to the Resnet support people and they said it would. It was also mentioned earlier in this thread that it would mess with a campus network

If you plug in the ports right on your router, you shouldn't mess up the campus network at all!

Right, that's NAT, but why will it mess with a campus network so badly? |

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?

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?

said by Nate425  :Not exactly. 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. 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... |

There's more than one way to skin a cat, chief. Each does the job just fine, now quit getting all pissy on me. I'm talking about the general masses that don't know anything about routers, you're talking about the people that can actually do stuff. Problem solved. |

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. |

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. |

"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 |

said by Nate425 :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. to use a router in a dorm for multiple pcs you would need DHCP.
just turn off the WAN access and DMZ zones...make sure to buy a cheap router too. |

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.

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. |
