Dorms not allowing routers question in Campus Broadband Chat http://www.dslreports.com/forum/r15097687 en Tue, 08 Dec 2009 21:24:01 EDT Tue, 08 Dec 2009 21:24:01 EDT Re: Dorms not allowing routers question http://www.dslreports.com/forum/remark,16741334 raid85 : 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.]]> http://www.dslreports.com/forum/remark,16741334 Sat, 19 Aug 2006 21:18:12 EDT Re: Dorms not allowing routers question http://www.dslreports.com/forum/remark,16740948 twizlar : Some of you need to stop giving advice when you know nothing.]]> http://www.dslreports.com/forum/remark,16740948 Sat, 19 Aug 2006 19:47:52 EDT Re: Dorms not allowing routers question http://www.dslreports.com/forum/remark,16651007 fegul : Thats all I needed to know, and thats exactly what I figured.

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.

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!

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?

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?

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...]]> http://www.dslreports.com/forum/remark,16064220 Tue, 09 May 2006 19:41:05 EDT Re: Dorms not allowing routers question http://www.dslreports.com/forum/remark,16029493 Nate425 : There's more than one way to skin a cat, chief.

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]]> http://www.dslreports.com/forum/remark,16022982 Wed, 03 May 2006 14:42:36 EDT Re: Dorms not allowing routers question http://www.dslreports.com/forum/remark,16022974 uid1307457 :

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.

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.

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.
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.

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.]]> http://www.dslreports.com/forum/remark,15112058 Tue, 27 Dec 2005 17:05:34 EDT Re: Dorms not allowing routers question http://www.dslreports.com/forum/remark,15099591 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.

Well, I've been running ICS off my laptop for quite sometime and I haven't been shut down yet.
