Target : Self.
Now, that I’m somewhat “ older, ” I may be “ ready, ” to take the plunge — into the deeper waters of netfilter’s innerworkings. 😉 😀 Nuh, not really, I’m just kidding ! Netfilter — Iptables, has a very steep learing curve ! In other words : Don’t blame me, if something goes wrong. I’m posting “ as is, ” 4 I’ll also assume, you’re sitting in front of your computer, and are not logged in remotely !
## A helpful hint : ## In case you get stuck ? ## Flush all rules, from the default chains. sudo iptables -F ## Flush all rules, from any userdefined chains. sudo iptables -X
So, while I promised — a few days ago — to write up a more thorough description on how to use IpTables, I remember, to have written up 5 something similar, in the past. But to be fair, how I thought back then, and now, are way too much apart for me to make use of it. 😉 Let me start afresh, and point you to some recommended reading, while I conjure up a basic configuration for you to use, if you so would choose ‽ But remember : It’s always better though, to figure things out for yourself !
Hence the Recommended reading :
- Targets, and jumps.
- Traversal of chains.
- Structure — Iptables
- Statemachine — Connection-state
Nuff said ! Let’s get to work.
