# Don't use MAC Address for VPN filtering

A little background story. I forgot to bring my laptop that have been registered to connect to the office network (through VPN). But, there's flaws in it, they used MAC address to register the person who wants to use the network, so I just need to borrow my friends laptop and change it to my MAC address.

Here's how I do it.

### 1. Get your MAC address
```bash
$ ifconfig
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=400<CHANNEL_IO>
	ether XX:XX:XX:XX:XX:XX  <-- here
	inet 192.168.100.10 netmask 0xffffff00 broadcast 192.168.100.255
	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect
	status: active
```

### 2. Turn down the interface of your PC/Laptop
Example of the interface name: **wlp4s0
**
```bash
sudo ip link set dev <interface> down
```



### 3. Change the MAC Address
***XX:XX:XX:XX:XX:XX*** --> is your MAC Address that you want to use.
```bash
sudo ip link set dev wlp4s0 address XX:XX:XX:XX:XX:XX
```



### 4. Turn up the interface again, with the new MAC Address 
```bash
sudo ip link set dev wlp4s0 up
```

Boom you can connect to the network !!!*
