iptables notes
Just some generic notes on working with IP tables. Can be a PITA when an issue is happening to remember the details..
REMEMBER: You can block YOURSELF if you do not use your head!
Dont block:
- Internal IP address
- YOURSELF external IP address (if logging in via public interfaces)
- Loopbacks... Not sure what would happen but expect it would brick things..
Simple blocks
- iptables -A INPUT -s 47.245.124.200 -j DROP
Reminders:
- This will not persist across reboots
- setup of fail2ban would be a heck of a lot easier than manual blocking
- iptables -L -n is your friend
