# IP Whitelist with TLSTCP Tunnel

Pinggy provides the capability of IP whitelisting, allowing access restrictions based on specified IP addresses or ranges. This feature permits connections solely from designated IP addresses while disregarding requests from other addresses without any response.

Start tunnel with IP Whitelisting as follows:


```bash
# SSH - no install, works anywhere the ssh client is available
ssh -p 443 -R0:localhost:8000 -t tlstcp@free.pinggy.io w:IP1
```

```bash
# Pinggy CLI - install with: npm install -g pinggy (or download the binary)
./pinggy -p 443 -R0:localhost:8000 -t tlstcp@free.pinggy.io w:IP1
```


Like basic authentication, one can set multiple ip addresses as well.


```bash
# SSH - no install, works anywhere the ssh client is available
ssh -p 443 -R0:localhost:8000 -t tlstcp@free.pinggy.io w:[IP1[,IP2[,IP3..]]]
```

```bash
# Pinggy CLI - install with: npm install -g pinggy (or download the binary)
./pinggy -p 443 -R0:localhost:8000 -t tlstcp@free.pinggy.io w:[IP1[,IP2[,IP3..]]]
```


You can customize the command here:


```bash
# TLSTCP tunnel forwarding localhost:8000
ssh -p 443 -R0:localhost:8000 free.pinggy.io
```
