Firewall configuration

There are a number of tools to configure firewall rules. Such tools are the simplest way to open new ports and add trusted hosts to firewall rules. If such a tool is not available, the iptables command such as available on Linux can be used from command line.

The following is an example of adding a firewall rule using iptables command to allow incoming packets on port 10080 from any source IP to any destination IP when the inbound rules are in chain “INPUT”.

# iptables -I INPUT -j ACCEPT -p tcp --state NEW --dport 10080 -s 0.0.0.0/0 -d 0.0.0.0/0

The following is a similar example showing a rule to allow all incoming connections from a trusted host, 192.168.1.23, such as an Amanda server to all network interfaces on the localhost.

# iptables -I INPUT -j ACCEPT -p all -s 192.168.1.23 -d 0.0.0.0/0
