This won't help in the slightest.

iptables works at the kernel level meaning that a flood that bypasses VAC will also bypass any iptables rules if it hasn't already exceeded the interface limits.

It's pretty much a resource for skids.

it's dead like all the other sub forums related to "hacking". I don't even know why this website is still called hackforums and not "moneymakingebookmarketplace.net".

And some of us are trying really damn hard!

damn, I forgot that I joined in 2019 and therefore cannot have memories about the time before. I apologize.
But honestly, there are almost no threads about real hacking here, only skids everywhere.
