Newbie moving forwards with firewall (slowly)



  • Can somebody explain firewall logs on my simple home network? My pfsense box is working for openVPN with transparent DNS, squid cache and I've got rules to open the standard IPV4 ports for browsing, email and ftp. Even learned about ports alias!

    In windows I've disable IPV6 but I'm seeing IPV6 port 53 (DNS) blockages, port 53 is open for IPV4?  I realize I've got to do something about Netbios ports since these are required for local file sharing? But am I right thinking I only allow Netbios calls within the LAN and not outside to the internet?

    I have a huge amount to learn, but any help to move forwards would be appreciated. If there is a repository of sample pfsense firewall setups somewhere, that would help me a lot because most of what I try stops something working. Most basic needs are 'working', but I'm assuming I shouldn't see firewall repeated blockages.

    If you don't use IPv6 on your network then IMO the best way to clear your logs of IPv6 noise is to allow it in pfSense (System / Advanced / Networking) then create a quick floating rule to block all IPv6 without logging it.

    Or you can block it in pfSense and choose not to log default rules (Status / System Logs / Settings).

    Either way works just depends on what you want to see in your logs.
