What do you run; Opnsense, pfsense, Smoothwall, maybe a WAF like wazuh?
Today was update/audit firewall day. I’m running a standalone instance of pFsense on a Protectli Vault FW4B - 4 Port - Intel Quad Core - 8GB RAM - 120GB mSATA SSD with unbound, pfBlockerNG, Suricata, ntopng, and heavily filtered. I did bump the swap to 8 GB as I’ve previously noticed a few ‘out of swap’ errors under load.
Before I signed off, I ran it through a couple porn sites to see if my adblocking strategy was working. Not one intrusive ad. Sweet!
Show me what you got.
I think I have the same protectli as you and it is awesome. Need it for my 2.5gb uplink. I use openwrt on it… Didn’t really like opnsense. I am more used to linux than bsd.
I host lots of services and get bombarded by scrapers, scanners, and skids both at home and on my VPSs.
I use ipset for the usual blocklists which I download regularly. I also have tarpits on 22/tcp (endlessh). I pipe the IPs from the endlessh logs into fail2ban which feeds the ipsets. I have ipset blocks and fail2ban on my home firewall and all VPSs and coordinate over mqtt. So
any fail2ban trigger > mqtt > every ipset block. Touch my 22/tcp anywhere and you get banned instantly everywhere. The program I use for this is called vallumd and it runs on openwrt.I also put maltrail everywhere but I’m not totally sure how to interpret and respond to the results. Probably will implement a pipe from maltrail to my mqtt > blocklist setup.
I don’t do any network-level adblocking… Might be a future project.
