Pfsense has configurations backup option it is a good practice to regularly backup configurations with encryption, especially after major changes and before upgrading pfSense. The catch is that rules are delayed 30 days after they have been released to Vulnerability Research Team (VRT) paid subscribers, they still a very good option for less targeted personal and SME use. If you registered a free account at Snort, simply copy your generated Oinkmaster code from your Snort account to Snort→ Global Settings. Many Websites/Services uses CDN (like Amai Technologies) where blocking many nearby countries will affect your connection, also noticed some CDN uses 'Undefined IPs' in continent countries list.įor improved Snort detection It is recommended to add registered users rules which are free. There is a time-saving button when using pfSense rules, where you can copy a certain rule, very helpful if you are creating similar rules with few modifications.īe careful when allowing AlexaTop Domains to whitelist when using DNSBL, Amazon Alexa ranks domains by the number of users visited these domains while using Alexa PUP toolbar, some malware domains can become on the top of Alexa domains.īlocking the world with pfblockerNG GeoIP will highly affect usability, more overhead on the system. PfSense pass/match followed by pfBlokerNG pass/match, then pfSense block/reject followed by pfBlokerNG block/reject. So it is recommended to configure pfBlokerNG rule order option -from pfBlokerNG → General → Rule order- to the second option, where it will make the order: PfBlokerNG by default adds its GeoIP and DNSBL rules on the top, even if you add an allow rule on the top the next Cron job will automatically place pfblockerNG rules on the top again and will make the allow connection blocked after the next cron. So it is better to keep the most restrictive rules down (you can drag rules up/down) and add allow rules on the top. Firewall rules work in orders from the top to bottom if a connection matched a rule no further checks will be made.įor example: if you have two rules, one to block all connections to 5358 TCP/UDP port on the top and another one to allow this port to a specified host down it, the host will be blocked because it will match the block all rule on the top.īut if you add the block to 5358 TCP/UDP down of the allow 5358 TCP/UDP to the host rule, the allow rule will match and allow the connection and no other rules get checked.
