Iptables Not Working With CSF
I have CSF installed on one of our server.

CSF dont ban the IP and if manually it is done I get following error.
----------------
csf -d 195.88.65.47
Adding 195.88.65.47 to csf.deny and iptables DROP...
iptables: Index of insertion too big
DROP all opt -- in !lo out * 195.88.65.47 -> 0.0.0.0/0
Error: iptables command [/sbin/iptables -v -I INPUT 2 -i ! lo -s 195.88.65.47 -j DROP] failed, at line 864
-------------------
Also iptables is not running on server.
If status is checked it says its stopped.

I have many sites on my server I dont want to get any downtime.

Please let us know how can we fix this issue as soon as possible.

I have tried reinstall CSF but still the issue remains same.

Iptables Block An IP Not Working
I use

iptables -I INPUT -s 60.216.238.212 -j DROP

To block ip, not working

After issue

netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

I can still see

87 218.86.252.158
163 219.150.191.62
301 60.216.238.212

60.216.238.212 still has 301 connection, any idea.

Basically, I use ddos-deflate to block ddos attack.
I already set the max conection to 25.
But it seems not working.
all the connections over 25 have not been blocked.
Did I miss something?
I mean after I issue

iptables -I INPUT -s 60.216.238.212 -j DROP

Do I need to do something like refresh iptables?

this in my Incoming packets rules..

Outgoing packets are all accepted..

so if i made connection from the server the input rules shuld accept them because it is established and related connection.. But it wont work.. any ideas about it..?
my vps is running on cent os 5.2 final..

After Flush+zero Iptables, Will A New Iptables Ban Work
I execute the following commands, in the following order:

iptables --flush
iptables --zero
iptables -A INPUT -s 218.65.12.161 -j DROP

will that last command successfully ban that IP until reboot?

If not, what needs to be done? I can't access my site if I don't flush + zero iptables first but I need to be able to ban with iptables.

IPTables
I've got two VPS's and both have the same ruleset for outbound EG_TCP

Code:
EGF="1"

EG_TCP_CPORTS="21,25,37,43,53,80,110,113,123,443,873,2089,3306"

EG_UDP_CPORTS="53,465,873,6277"
Whenever I turn EGF to 1 my VPS locks me out of everything, I need togo into hyperVM to turn it off and restart my firewall.

What would cause this?

It's Fedora Core 5 on OpenVZ i've googled and cannot seem to find a reason why it would do that. Could be something in the host node kernel that may need adjusting?

Now I just went ahead and put this on one of the servers, one that I really don't need the traffic on. But I am wondering what kind of affect this may have on the speeds. Will it really affect it more then a few ms? And anything else I should maybe worry about? Except maybe the loading time at reboots.

to block IP, and

service iptables save

But when i run netstat command abouve, i found IP are attacking still available, it seem iptables don't block it?

Iptables Rules
One of my low knowledge area's is Iptables Rule's I just normally use APF/CSF.

However on a VPS Host node, I basically want to block all access to a certain port let's say 1234 apart from a certain IP address.

However I don't want to block this port on any of the VPS's on the Node, so what Iptable Rule(s) would I need to put into a bash script on startup.

How Do I Disable IPTables?
I installed APF/BFD a log time ago on my centos server and have had no problems up until now.

Approx 3 days ago, the server was uncontactable by SSH/HTTP/FTP. So I ran a traceroute and the host confirmed the box was up with no problems.

He disabled IPTables and I was allowed in. Anyway, overnight, the same thing has happenned again.

I will have to SSH in from another IP however, my main question is how do I disable IPTables ? Or better still, how do I uninstall APF!

Configuring My Iptables
I saw an ad on WHT by LimeStone Networks and decided to get a server from them. My server was made within few hours. On the server, I was only able to connect to the SSH on port 22, I could not login to the DirectAdmin or anything.

So, I tried shutting down the "iptables" firewall like this:

Code:
service iptables stop
and then tried to access the directadmin like this:

[url]

and it worked. So, the problem is that, my host only configured ssh on my server and didnt configure the rest.

How do I open the rest of ports, e.g.

2222 (directadmin)
80 (web server)
21 (ftp)
443 (https)
3306 (mysql)

etc... ?

on the welcome email, this is what they said about the firewall, but I don't quite understand

Quote:

Please be advised that your server's firewall is active for your protection and will only accept connections on port 22/tcp by default.

If you modify firewall or IPTable rules on your server, please be sure to have them configured to allow inbound and outbound traffic on all ports (TCP & UDP 1-65535) from 209.130.152.0/28.

How Many IP Address U Blocked On IPtables
for about only 3 months running, my server iptables has 36 ipaddresses blocked so far (most of them are from .edu.cn and .edu.tw, dunno why? maybe because of summer break hehe..).
Those IP got blocked mostly because of SSH bruteforce. Everytime I noticed any SSH bruteforce on my /var/log/secure, I just issued "iptables -A INPUT -p all -s [ipaddress] -j DROP"

so, I'm just curious, how about yours ? how many IP in your blocked lists?

My Own IP Keeps Getting Added To Iptables Rules
I had csf firewall installed, and due to my own stupidity, attempted to login with the wrong password one too many times, which added my IP to iptables, locking me out. I had to SSH into a linux box at school, and then ssh into my server to stop the iptables service so I could get into my server.

I removed every trace of my IP that I could find in csf, but sometime in the middle of the night, iptables reloads some rules from somewhere that blocks me again. I also tried doing iptables -F to clear all rules, but again, sometime in the middle of the night, rules are reloaded and I get blocked. I even uninstalled csf to no avail. I just want to remove my IP once and for all.

I Have To Flush Iptables On Every Reboot
I'm running CentOS 4.4 32 bit.

At the moment every time I reboot my server I have to execute:
# iptables --flush
# iptables --zero

just to be able to access the server. (Though it does allow SSH to access before executing those).

And I figured out that I must do something to /etc/sysconfig/iptables to permanently be able to access the server without those commands after reboot. Right?

Below is the file's contents:

# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.

IPTABLES (Linux Firewalls)
IPTABLES(Linux Firewalls)

Use Of Iptables?

Filtering packets based on a MAC address and the values of the flags in the TCP header. This is helpful in preventing attacks using malformed packets and in restricting access from locally attached servers to other networks in spite of their IP addresses.

Firewall also keeps track of each connection passing through it and in certaincases will view the contents of data flows in an attempt to anticipate the next action of certain protocols. This is an important feature in the support of active FTP and DNS, as well as many other network services.

How IP Tables works?

All packets inspected by iptables pass through a sequence of built-in tables (queues) for processing. Each of these queues is dedicated to a particular type of packet activity and is controlled by an associated packet transformation/filtering chain.

There are three tables in total. The first is the mangle table which is responsible for the alteration of quality of service bits in the TCP header. This is hardly used in a home or SOHO environment.

The second table is the filter queue which is responsible for packet filtering. It has three built-in chains in which you can place your firewall policy rules.

a) INPUT Table b) OUTPUT Table c) FORWARD Table

General Syntax of the iptables is as follows:

IPTABLES -A {INPUT,OUTPUT,FORWARD} -p {tcp,udp} --sport(dport) -s {ip} -j {DROP,REJECT,ACCEPT}

To Block the incomming ip:
IPTABLES -A OUTPUT -p tcp --sport{1..65535} -s {ipaddress} -j DROP {REJECT}
To Block the outcomming ip:
IPTABLES -A INPUT -p tcp --sport{1..65535} -s {ipaddress} -j DROP {REJECT}

You can also use --dport instead of --sport & you can use -d instead of -s which specifies source or destination respectively.
