Hi E1-531g,
Thank you for your quick response. I will have a go with a single firewall as you have suggested. Then may add the second firewall later to see how it goes. In my original plan for having two controlled firewalls because the most common static ports 25, 53, 80, 110, 443, 445, etc. are always opened to allow malware software attack for any unauthorised data leaks, botnets, backdoor access, etc. for sending back to bad guys or even rouge spooks/hackers who knows. That is why I was thinking a firewall to control ax88179 USB 3.0 to Ethernet traffic to wireless router box could close all these static ports in firewall’s end and use proxy’s customised port numbers. Firewall to control NIC traffic that connected to modem box may open these ports through the firewall’s filtered known IP addresses to support Privoxy and email gateway. Hope this make more sense. :-)
If Privoxy becoming less useful, is there any other better web content filtering software tool to support openbsd platform? Just curious thanks.
