What should I do if I get a dns attack when I connect to vpn intra?

Question

VPN

Answer 1

sniffer help!

Answer 2

Panic, run, occupy the nearest bunker.
"Having a DNS attack" (now) and "susceptibility to DNS attacks" (generally in principle) are completely different things. The program simply warns that the device may use DNS queries that it does not protect. Why does it warn? Insecurity is better than a sense of false security.

Answer 3

There is a problem: after restarting the browser, the session crashes.

This is not a problem, this is the duration of the session.
You can increase its lifetime in php.ini or locally in .htaccess
