iptables block access to port 8000 except from IP address

Question

I\'ve never used iptables, and the documentation online seems a bit opaque.

I\'d like to block all requests to port 8000 on my server except those coming from a spec

Answer 1

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

iptables-restore < myfile and you're good to go.  

REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.
