The <b>Open Ports on Router</b> section provides a quick way to set simple rules that allow traffic on specified ports of the device. The figure below is an example of the Open ports on device section and the table below provides information on the fields contained in that section:
In the <b>Add new instance</b> section, select <b>Open ports on router</b>. This provides a quick way to set simple rules that allow traffic on specified ports of the device. The figure below is an example of the Open ports on device section and the table below provides information on the fields contained in that section:

==Custom Rules==
The <b>Custom rules</b> tab provides you with the possibility to execute <b>iptables</b> commands which are not otherwise covered by the device's firewall framework. The commands are executed after each firewall restart, right after the default rule set has been loaded.
The figure below is an example of the Custom rules tab:
[[File:Networking_rutos_manual_firewall_custom_rules.png|border|class=tlt-border]]
The rules added here are saved in the <b>/etc/firewall.user</b> file. Feel free to edit that file instead for the same effect in case you don't have access to the device's WebUI.
The <b>Save</b> button restarts the firewall service. Thus, adding the custom rules specified in this section to the device's list of firewall rules.
The <b>Reset</b> button resets the custom rules field to its default state.
