Can anyone work how to do this please!!

Right,

I have moved into a privatly owned university accommodation,

Its all studio flat and are brand new and nice,

The internet however is through a ethernet cable, on theier home page where you sign in it says you can upgrade to wireless for £45.00 which includes router.

Do you think that i would be able to simply plug in my own router and it would work ?

I want to also use my ps3 online off this, will i need to mac addresses for this etc ???

Bit confused

If you use a NATing router you may just about get away with it, as they'll only see you using one IP address.

So using a NATing router would be fine.

Possibly its impossible to say for certain but if you use a cable router with NAT enabled the buildings network will only see 1 device connected.

Surely if the op uses a nat router in the already internal network then its gonna have to use DHCP to pick up an ip from the buldings router.
But it will also need to hand out IP's to its own network. Not sure how the subnetting will work with that. May depend on the router.
Might be better to just use your router as a switch so you can at least plug in more than one device and get internet access. It will just collect an IP from the buildings DHCP server. Unless they closely monitor ALL connections (with a managed switch) they'll just see all your devices as IP's on the whole network.

Im not sure I understand your post but I think you are wrong.

The WAN port on the router will be given an IP from the buildings router/DHCP server.

The LAN ports on the router will be served by the internal DHCP. Then all traffic will go out over the WAN port using that IP address, thats what NAT is!

Pretty much in the same way a standard ADSL or cable router works then? =P

Quite simply, he sets up his router so that the WAN side is the IP address that gets assigned from the buildings DHCP, and he sets his LAN side up to be in a different range. Internal DHCP server of the router will then assign IP addresses from his chosen range to his personal client machines.

The building sees one device connected (the router), and he gains his own internal LAN.

Depending on the uni, they could well monitor everything. At Durham, where I was, you had to give the MAC address of your NIC and then only use that one. If you plugged in a computer with a different MAC address, the port would be locked and you'd have to request that it be unlocked.

Hmm. There's a thing. If they ask for a MAC address, OP will have to give the MAC address of the WAN port on his router.

depends on the terms of your contract, I work for the department that provides halls of residence connections for Manchester Uni and a fair amount of private halls in Manchester, and our terms strictly state that it's against the rules and will lead to disconnection. Even with a NAT'ing router there are giveaway signs which would expose you as having multiple devices connected, not being a network bod I'm not sure what those are though.

Most routers have the functionality to set the MAC address manually or automatically to that of the PC

Banzai_Joe · 6 Oct 2009 at 13:55

after mulling it over and BEFORE you lot shot my theory down

, i'd already realised the flaw....but thanks for confriming that i was right in being wrong!

It was jsut a test to see if you were all napping.....you passed....good...carry on!
:rolleyes:

Students don't give a fig about rules and regs though. All they want to do is play WOW and lift up spliffs......surely!?

Those that get disconnected in the first week and are left without internet for a year do tend to care

Banzai_Joe · 6 Oct 2009 at 14:34

they'll be too high to care.

Says a lot about the institution if it's happy to take afew grand off someone then leave them without, what has become, virtually a critical resource. Any institution relying on the totally secure mac addresses, or deliberately piling up problems for lost/stolen/replaced gear, well go figure..

Anyway, find out if vpn still works, if it does pick up a router that runs dd-wrt and setup vpn via the router, plug your stuff into and and you're set. The catch is you'll need to pay ~8 quid a month to a vpn provider but it works, although most people use vpns over uni networks for security usually.

If that doesn't work then you need to look into (again pay for) http tunnelling, i.e. sending everything down port 80. The problem here is you're laptop is essentially the gateway i.e. it would always need to be on with the rotuer plugged into it. Sub-netting could be a small nightmare that way
