IPTABLES - How to allow all packets from a certain address

exitsfunnel · 09-06-2005, 09:17 PM

Hello,

I'm running RHEL 4.0 and not much of a networking expert and know next to nothing about IPTABLES beyond the fact that I think that they are running

I'm trying to connect to the linux box from a windows client on port 1423 but the client is getting a destination unreachable error. By fumbling around around with ethereal I've determined that the packets are showing up but it seems that they are being rejected. I'm guessing that this is a firewall issue. I'm a bit desparate at the moment and don't have time to come up to speed with IPTABLES so I was wondering if someone could just give me the command to allow ALL packets from a particular IP Address. Also, the command to undo it when I'm done would be helpful

Thanks in advance.

open for IP:

Code:

iptables -I INPUT -j ACCEPT -s {{INSERT_IP_HERE}}

When finished, replace -I with -D and run again.
