I'm trying to set UFW (using GUFW) to create a firewall that only allows network connections when OpenVPN is connected.
So in GUFW I deny incoming and outgoing connections and enable the Firewall. I then create a rule that allows incoming/outgoing of the openvpn service.
Interestingly, with these settings I'm able to make a VPN connection using Network Connections, however I'm unable to browse. Note that without these rules I'm unable to make the VPN connection.
I've also tried creating a rule using the OpenVPN ports and VPN IP address with no success.
To troubleshoot, I delete those rules and create more broad rules of allowing incoming/outgoing HTTP and HTTPS. With these rules in place, I'm still unable to browse online. I tried this while creating rules with my IP address, and no luck.
Here's an example of my current rules, which is not allowing me to browse.
user1@vuser-pc1:~$ sudo ufw status Status: active To Action From -- ------ ---- 80/tcp ALLOW Anywhere 443/tcp ALLOW Anywhere 80/tcp ALLOW Anywhere (v6) 443/tcp ALLOW Anywhere (v6) 80/tcp ALLOW OUT Anywhere 443/tcp ALLOW OUT Anywhere 80/tcp ALLOW OUT Anywhere (v6) 443/tcp ALLOW OUT Anywhere (v6)
Is there something I'm doing wrong?
Edit: If I set "allow" outgoing, and then create rules to disallow http/https connections, the rules work. I cannot browse. It is strange to me that in this case the rules work to disallow, but I can't get it to allow.
