I’ve actually had an excavator take out my network. I’ve also had networks taken out by forklift, train, and a semi-truck towing three other semi-trucks.
That punchline hit like a tree falling onto a network cable.
Spanning tree is a firewall
Okay, that’s just cursed.
I’ve heard of almost all of those things.
What’s a HA proxy?
It’s a lolbalancer
Without it we might accidentally Lol or lOL. It would be anarchy
http://www.haproxy.org/ it’s a load-balancer (it only allows access to devices behind it based on rules).
i wonder what is the favorite firewall of people here?
I’m at the top right myself. 😆
Not as fast as ASIC firewalls, but way more flexible and fast enough for home routing.
In my apartment, I have a PC running Linux with four network interfaces:
- One Ethernet port built into the motherboard, connected to a switch that the rest of my hard-wired devices are connected to
- One PCIe Wi-Fi 5 card, serving as my apartment’s wireless access point
- One USB Ethernet dongle, connected to my ISP’s optical network terminal
- One USB Ethernet dongle, connected directly to an employer’s PC (for working from home)
It forwards packets between all of these (i.e. is a router) and uses nftables (i.e. is a firewall).
The firewall is specially configured to isolate interface 4: it is only allowed to talk to the Internet and the router’s DHCP and DNS servers, but not any other device in my apartment, nor any other process running on the router itself.
Seems pretty radical on both axes, but it’s neat that I can do this with nothing but common consumer equipment and free software. No fancy Cisco gear required. And unlike the average home router, the software running on mine actually receives security audits and patches, so I consider it far more secure.
Cisco Automatic Telecommunications Excavator: for all your internet connection restricting needs!
A firewall is when I redirect stuff to 0.0.0.0 in /etc/hosts
Ah yes, that time a Georgian granny became the Great Firewall of Armenia.
