Following this tutorial, I only allowed connections that are routed through my OpenVPN connection. However, this also results in me not being able to establish a connection in the Tor Browser. Is there a way to also explicitly allow Tor connections through iptables? These are my current settings:
:INPUT DROP [137:9139]
:FORWARD DROP [0:0]
:OUTPUT DROP [0:0]
-A INPUT -m state --state ESTABLISHED -j ACCEPT
-A OUTPUT -m owner --gid-owner openvpn -j ACCEPT
-A OUTPUT -o lo -j ACCEPT
-A OUTPUT -o tun+ -j ACCEPT
