iptables rules

chrisfirestar · 10-28-2003, 11:13 PM

Hi
Setting up an IP Tables Firewall... the requirements are as follows...

External Blocked on all ports - Internal
Internal Blocked on all ports except essential ones - External

eg 80, 22, 23, 443, 110, 25, 23

This box will not be handling DHCP but probably require masquerading

can someone paste some examples of what I should be typing into the shell? and what my iptables file should look like

Greetings!

If you do not have much knowledge of iptables, I suggest you take a look into firewall builder. You can make complex configurations with it under a nice gui and it will compile a working iptables script for you. You can use it and/or look into it to see how certain rules are implemented.

Good luck!

Hmm, I just noticed that you crossposted this one. It's the exact same post in 'Security' and 'Networking'. Pls don't do that anymore, the moderators don't seem to like it.

'Nuff said.
