Blog Firewall configuration recommendations

Hi guys,

Sorry for my late response. I couldn’t login on this forum for some time and than corona decided to pay us a visit. All okay now,

Yes, that’s the blog I meant.
My first question seems to be answered here. So the answer to " Right?" is " Yes" if I interpret it al well. But:
I already configured the webproxy and it works well. Windows computers do pickup the proxy.pac, on android phones I had to configure the proxy manually.
I applied the rules for DNS, NTP etc. When I change the default forward and outgoing behavior to Drop, internet browsing isn’t possible anymore. So there is still something not done right.
I do see the firewall make connections to my DNS servers (DNS watch).

On the other questions (OpenVPN, DDNS) I didn’t find an answer yet.

Regards,
Edwin.
