Firewall Alignment Chart

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.

How about a bus? The fiber to a datacenter i used to work at kept going out at almost consistent intervals during almost normal business hours. Turns out the conduit wasn't deep enough and the city built a bus stop on top of it and it would sag just enough to go out but only when a bus was at the stop.

That's pretty similar with what happened with me and the train. Kept getting random drops from a plant. I went out to investigate and everything tested perfect and the network was staying up. That was until a freight train rolled by. Turns out AT&T had run the line by shoving a piece of PVC through the gravel between two cross-ties, then running the cable through it.

Ah yes, that time a Georgian granny became the Great Firewall of Armenia.

That punchline hit like a tree falling onto a network cable.

This is wrong, I use IPTables but the device is absolutely not dedicated lol.

The iptables one has me triggered.

Who needs all this crazy firewall stuff when I have my

iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -i ppp0 -j DROP

And for IPv6 you don't need a firewall, just use slaac and hope no one finds the address /s

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.
