Your internal hosts need to use officially registered IP addresses in this case.
RAW, this table is used mainly for configuring exemptions from connection tracking in combination with the notrack target.
D/snmpd start snmpwalk -v1 -c fwuser localhost system chkconfig ford 8n tractor manual snmpd on Now you will want to install mrtg, create the relevant directories and configure.You could also use a firewall to separate a "testing network" from a production network, especially if you need Internet Access for your testing network.Httpd_accel_host virtual httpd_accel_port 80 httpd_accel_with_proxy on httpd_accel_uses_host_header on, then you need to change your firewall settings to redirect any http traffic coming from your network to the proxy server.To run mrtg issue the following command: env langc /usr/bin/mrtg /etc/mrtg/g Now that it works correctly, you need to "prep" the webpage using the following command: indexmaker /etc/mrtg/g mrtg needs to be ran periodically to collect all the data it needs to process.Linux-w2mu # iptables -A input -p tcp dport 22 -j LOG log-prefix "Someone knocked on port 22" linux-w2mu # iptables -A input -s -p tcp -dport 22 -j drop Figure.1: Correct order.FW_customrules (firewall uncomment this variable to install custom rules.The firewall rule sets are created by entering rcSuSEfirewall2 start as root.The only possible disadvantage is that you need to write out each rule manually and make sure the ordering is correct set.
This is called implementing a "Transparent Proxy".
