Problem when connecting via VPN to wifi on public networks, from a computer blocked by WiFree Software

Solution: [[WiFree Software

  1. Connect to wifi on public networks via VPN using a computer that is blocked by WiFree|see here]].

Network problems that may occur in this connection type

Routing internal addresses

There may be no connection to the local network when you are connected to the VPN (the problem can usually be solved by routing)

Instructions for routing are listed below: Routing addresses to the internal network

The routing role is to cause some of the traffic not to pass through the VPN but through the internal network

To do this, we must instruct the computer to route a specific address or group of addresses (range) through the local network adapter.

Sample command:

route -p add 10.0.0.0 mask 255.255.255.255 1.1.1.1 metric 1‏

The command "route print" will display the routing table where to locate the gateway (GW)

The command "route -p add" performs the routing

The parameters are: 1) The address you want to route (10.0.0.0)

2) The next parameter is the mask (255.255.255.255)

This is for cases when routing a group of addresses and not a single address.

The common denominator of all inscriptions should be their beginning - which is all the same.

In such cases in the first parameter we will write a representative sample address, and in the current parameter we will write whow much of the end can change.

For example, for all addresses beginning with 10.0.0, we will write in the first parameter 10.0.0.0 and 255.255.255.0, meaning that the first three groups are 255, the last group does not matter 0.

225 means precisely, that is, precisely the exact address of the first parameter, and zero means that no matter what is in this group.

If we do not enter this parameter in the command, the mask will default to 255.255.255.255

To route a set of addresses

Do it with a mask like this for example: mask 255.255.255.0‏

The zero in the end says no matter what happens there.

Where it says 255 means that it mast be the same.

Ie 10.10.10.32 will match, 10.20.20.0 will not match

3) The next parameter (1.1.1.1 ) is the GW to which the routing is performed.

Cancel routing:

הפקודה route delete‏, למשל:

route delete 10.0.0.0 mask 255.255.255.255 1.1.1.1 metric 1‏

The arguments are the same as "route add‏ only without the flag "-p"‏

Finding the internal address of network drives:

You enter the drive, write down the computer name above‏,

Run the command ping drive-name‏ and you know what the IP is.
