PureVPN IPv6 Leak

by anagogistis anagogistis.com published 2025-09-174 min read

Two findings in PureVPN on Ubuntu 24.04. After a reconnect the system takes a default IPv6 route outside the tunnel, and the ip6tables OUTPUT policy is still ACCEPT, so traffic leaves in the clear while the client reports connected.
