Installing firewall help

hey I got this off another site... I want to install it however
im abit stuck after the first bit

I get this, that seems easy ...

cd /usr/src
wget http://rfxnetworks.net/downloads/apf-current.tar.gz
tar -zxf apf-current.tar.gz
cd apf-0.*
./install.sh


Now edit config file
#pico -w /etc/apf/conf.apf

Change the following:
USE_DS="1"
USE_AD="1"



But after that whats all this mean



Scroll down to this section:


# Common ingress (inbound) TCP ports IG_TCP_CPORTS="20,21,22,25,26,53,80,110,143,443,465,993,995,2082,2083,2086,2087,2095,2096"
# Common ingress (inbound) UDP ports
IG_UDP_CPORTS="21,53,465,873"

# Common ICMP (inbound) types
# 'internals/icmp.types' for type definition; 'all' is wildcard for any
IG_ICMP_TYPES="3,5,11,0,30,8"


Scroll down a bit then find this section:

EGF="1"
# Common egress (outbound) TCP ports EG_TCP_CPORTS="21,22,25,26,27,37,43,53,80,110,113,443,465,873,2089"
# Common egress (outbound) UDP ports
EG_UDP_CPORTS="20,21,53,123,465,873"


Save the file and start apf via.
apf -s
If everything still works then edit the config file and turn dev mode off.
DEVM="0"

Now restart APF
#apf -r






----------

A firewall should be the first thing installed.. I recommend advanced protection firewall (APF) by rfxnetworks. APF will block unused outgoing and incoming ports. It can also be configured to use information from some block lists.

#cd /usr/src
#wget http://rfxnetworks.net/downloads/apf-current.tar.gz
#tar -zxf apf-current.tar.gz
#cd apf-0.*
#./install.sh

Now edit config file
#pico -w /etc/apf/conf.apf

Change the following:
USE_DS="1"
USE_AD="1"

In all honesty I do not think it is smart nor secure to discuss your firewall setup in a forum.

Its simple to install, first download APF Firewall

# cd
# wget http://rfxnetworks.net/downloads/apf-current.tar.gz

Then uncomptress it

# tar -zxvf apf-current.tar.gz

then go to the folder

# cd apf-0.*

Now install the Firewall

# ./install.sh

Now your firewall is installed and you need to configure it. You can do this by editing conf.apf file, go through the comments and try to understand :-)

# vi /etc/apf/conf.apf

If you need any help, PM me.

This is just of another forum .. there are no server login details etc...


thanks its set up now
