I'm following this guide here: http://isalazyadmin.net/2009/07/02/configuring-a-basic-firewall-for-debi...

And I have the iptables listed shown, but my server still appears to be accepting all incoming connections (ie: bittorrent peers are still connecting, even though I didn't allow those ports).

/etc/iptables.rules

*filter

# This will allow all loopback (lo0) traffic and drop all traff

How do I use iptables to reject all traffic to localhost port 80 but allow the one that comes from local machine?

Here is my current solution that doesn't seems to block the traffic. the ip, the the ip of the local machine.

I've setup IPTables with the following script...

Possible Duplicate: iptables: forward port 80 to port 8080

I'd like to forward port 80 to 8080. So I tried to edit /etc/syscongfig/iptables:

-A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

But got:

# service iptables restart iptables: Flushing firewall rules: [ OK ] iptables: Setting chains to policy ACCEPT: filter [ OK

I'm trying to find out why changing my default iptables policy is affecting what nmap sees when it scans my host.

Consider the following iptables setup:

iptables -F iptables -A INPUT -p tcp -s 10.1.0.0/20 --dport 22 -j ACCEPT

iptables -P INPUT ACCEPT iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT

iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -m state --state ESTABLISHED,RELATED -j AC

My table rules:

sudo iptables -L --line-numbers

Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- anywhere anywhere tcp dpt:http 2 ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED 3 ACCEPT icmp -- anywhere anywhere 4 ACCEPT all -- anywhere

I used an online tool to create an iptables firewall. Basically I just need port 22 and 1194 open to the outside world. But I noticed this bash script has input, forward and output chains as accept by default. Is it blocking all traffic but those two ports? Thanks.

I'm trying to set up iptables to block all traffic except ssh but, no matter what I do, it's blocking outgoing ssh. The commands that I'm using are shown below. Oddly, I can SSH into the box, just not out.

I cannot deny access to FTP for a IP address.
