Sharing a Networking Config that I Found out Earlier Today.

post #1 of 6
Thread Starter 
Hey everyone,

I just found out a interesting piece of technology when I was playing around with the internet settings.

If you know about this already, then I'm sorry, But if I taught 1 person, It is worth it.
.


.

The Modem, to PC, TO ROUTER. Your desktop will have the dibs on speed before the router is connected and spreading your connection to other devices, Which will give you faster speeds.. I realized the security with this setup, but if someone wants it to be convenient than i say give it a shot.

Im Copying What The Help Center Told Me and pasting into the spoler Alert below.
.
. Windows Help Center about ICS (Click to show)

Using ICS (Internet Connection Sharing)

In this article
• How does ICS work?
• Enabling ICS
• Configure TCP/IP
• ICS and VPN connections
• ICS and ad hoc networks

If you want to share one Internet connection among several computers, you have two options:
• Use Internet Connection Sharing (ICS).
• Use a router.
.
.
.
How does ICS work?
First, you'll need one computer, called the host computer, that's connected to the Internet and that has a separate connection to the other computers on your network. You'll enable ICS on the Internet connection. The other computers on your network then connect to the host computer, and from there to the Internet through the host computer's shared Internet connection.
A network using Internet Connection Sharing (ICS)
Enabling ICS
To enable ICS, on your host computer:
1. Click to open Network Connections.
2. Right-click the connection that you want to share, and then click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click the Sharing tab, and then select the Allow other network users to connect through this computer’s Internet connection check box.



Notes
o The Sharing tab won't be available if you have only one network connection.
o You can choose whether to select the Allow other network users to control or disable the shared Internet connection check box.
o Optionally, to allow other network users to use services running on your network, click Settings, and then select the services you want to allow.
When you enable ICS, your local area network (LAN) connection gets a new static IP address and configuration, so you'll need to reestablish any TCP/IP connections between your host computer and the other network computers.
To test your network and Internet connection, see if you can share files between computers and make sure each computer can reach a website.
Configure TCP/IP
To use ICS, make sure the local area network (LAN) connection on each network computer is configured to get an IP address automatically. To do this:
1. Click to open Network Connections.
2. Right-click the LAN connection, and then click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties.
4. Click Obtain an IP address automatically or Obtain an IPv6 address automatically, and then click OK.
The Internet options on your network computers should also be configured for ICS. For more information, see Change Internet settings for ICS (Internet Connection Sharing).
Don't use ICS on a network with domain controllers, DNS servers, gateways, or DHCP servers. And don't use ICS on systems configured for static IP addresses.
ICS and VPN connections
If you create a virtual private network (VPN) connection on your host computer to a corporate network and then enable ICS on that connection, all Internet traffic is routed to the corporate network and all of the computers on your home network can access the corporate network. If you don't enable ICS on the VPN connection, other computers won't have access to the Internet or corporate network while the VPN connection is active on the host computer.

ICS and ad hoc networks
If you share your Internet connection on an ad hoc network, ICS will be disabled if:
• You disconnect from the ad hoc network.
• You create a new ad hoc network without disconnecting from the ad hoc network for which you enabled ICS.
• You log off and then log back on (without disconnecting from the ad hoc network).




Once again, if Im really slow to figuring this out, Im sorry. But I found it and just could remember a lot of people asking about that configuration. And I couldn't find one place where the question was deemed possible/effective. Since I was looking for that config for awhile, Its nice just to know the option is there, even if we don't use it.

Hope this helps somebody out.

In all honesty that's a pretty rigged 'solution'.

You lose the protection of being behind a NAT router, though. This means that outsiders can try to open connections to your PC when otherwise you would have had to have opened a connection to the outside world, first.

Router with QoS tongue.gif.
It works but isn't the most ideal solution.

Kudos for the work though!

Hey everyone thanks for the informative responses.

Like I said, this isn't the Best Option in the Security Department, but if you have the proper coverage with software, (firewall, peerblock, Anti-Malware, Anti-Virus, Ect.) it should limit the risks.

The answer I wanted to point out, was the QoS option.

This is an excellent solution if you can set it up, BUT if you don't have a half decent or older router, your speeds may drop because the router can only handle so much.

This was an issue of mine, which is how I stumbled upon this setting. But I managed to find the problem.

For some reason, Behind my router, even with QoS on, my speedtest.net results were perfect on download, but terrible on upload.

My ISP Advertised Speeds:
DL = 15mb/s
UL = 5mb/s

Setup 1 : PC > Router > Modem:

DL = 18mb/s
UL = .63mb/s

Setup 2 : PC > Modem:

DL = 18mb/s
UL = 3.5mb/s

Solution:
I am receiving the correct speeds from my ISP, but when the router gets involved, my upload is almost non-existant.
- I was messing around in the router settings (192.168.1.1)
- And Somewhere in the WAN or LAN settings, it gave you a space to manually enter your uplink speed in ms/s (Correct me if Im wrong on the units)
- It was automatically put at like 1000, and I decided to increase that because it may increase how upload speed is handled.
- I put it to 3000, saw a jump in speed, put it to 5000, saw a jump in speed, and it bellied-out at 7000 where the speed seemed to be the best i can go.

Now even when my PC is connected to the router, to the modem, I am receiving my advertised speeds!

Sorry for the tangent, just figured I share my solution to my problem, in case others are in the same boat.

Nice improvement in upload speed and nice work on this thread but I'm not entirely sure that this is worth all of the potential security risks, I don't think I would try it myself but others may.
