Is it true or not?

Question

SSH

We draw the attention of those users who are going to use the SSH tunnel to hide their real IP address, for the purpose of anonymity. Many browsers (Opera, Google Chrome, etc.) and other programs (for example, Skype), no matter what settings you use to connect to the network, try to establish direct service connections bypassing the proxy. This, of course, instantly negates your anonymity by revealing your real IP address.
To eliminate such exposure, it is necessary in the firewall rules to prohibit outgoing connections for all programs, except for the connection to your proxy address (127.0.0.1). And allow the Bitvise SSH Client program to make an outgoing connection to the SSH server address. In this case, anonymity will be observed impeccably.
