What is this called?

[2FA]

Say you have two computers and a switch. Assume only only one port on the switch is available. If one of the computers, computer 1, has two NICs, what is it called when I have computer 1 connected to the switch and then connecting computer 2 to computer 1 via the other ethernet port to allow for internet access.

I don't think that's it. I have the term before but I can't for the life of me think of what it is.

Is it perhaps port forwarding?

Link Aggregation?

Passthrough?

Port forwarding is just setting the ports in a router, not physical ethernet ports, to forward packets to a specific port. 

 

Link aggregation?

Link aggregation is meant to be used in parallel to increase bandwidth. This is more of a serial connection.

 

Link Aggregation?

Passthrough?

Network bridge?

Network bridge, a software one, is probably the closest.

Internet connection sharing?

[2FA]

Basically the reason why I'm asking is because my college dorm only has one ethernet wall port per person and if it detects more than MAC address, it will block all connections to that port. Apparently to stop people from using switches in their dorms. I was considering getting a cheap Linux box to mess around with.

Apparently most of you have no idea, since 99% of the suggestions are incorrect

The term you are looking for is indeed network bridging. You are bridging the two network adapters so that one feeds the other.

You can bridge two connections (both Ethernet, one Ethernet and one Wi-Fi, or both Wi-Fi) using the control panel network adapters page.

Thank you verifying that. I figured most wouldn't know too much Networking stuff.

Internet connection sharing?

Yep, that's Microsoft's vendor specific branding for Network Bridging. The terms can be used interchangeably (Although technically, ICS only refers to Windows based machines, whereas Network Bridging can refer to the process on any OS).

[CWP]

I have reservations with using network bridging in this scenario. My understanding of this is that it will send your second box's MAC address as-is, which means the campus's switch will detect two MAC addresses coming from your port and shut it down.

 

Windows Internet Connection Sharing turns your computer into a glorified router, which greatly improves your chances of getting Internet to your second box without triggering the port security. Alternatively, if you are allowed to, you can also use a router instead of ICS. Be sure to check your terms of use or acceptable use policy on what is allowed.

Network Bridging and Windows ICS are essentially the same thing in this scenario. ICS is simply the name of the Windows Feature which provides Network Bridging.

 

Also, you can use NAT (Which is, IIRC, the default method in Windows ICS), which will route all traffic from the second computer through the IP Address of the computer running ICS.

 

This way, the switch, and by extension, the network as a whole, cannot tell that you have an additional computer connected via Network Bridging.

Smart Lady. I guess they don't want to make any exceptions and change the network config? Probably a hassle for the few exceptions they would allow.

[vanished]

I know in Ubuntu there is a built in feature to have it report a different MAC address than your real one without having to know any hacks... at least for wifi.  I've never tried but I don't see why it wouldn't work for wired as well.  Then, the solution is to set all machines to the same one so it can't tell it's multiple machines

 

Or use some fancier router that doesn't pass through that information, so it shows up to the school like one device but can have many connected to it.

[leadeater]

Would be a whole lot easier to use a cheap router with an ethernet WAN port. Setup the WAN port with the correct IP settings or DHCP and the basic NAT functions of home routers will do the reset. Quick, cheap and gives you more independence rather than being reliant on the computer with the main LAN connection.

Substitute the modem in the diagram for the dorm LAN connection.

Nah it'es really just a way to keep people from setting up their own sub-networks in their dorms and eating of the school's bandwidth for personal profit. Makes sense really.
