    Ubuntu has an inbuilt firewall caled ufw

    The graphical version for it is gufw. Search in the Ubuntu Software Center you will find it

    Ufw is installed by default and is one of the strongest firewalls ever

    See this Ubuntu Documentation for Firewalls


    Regarding an Antivirus software, you dont need one because linux rarely catches a virus.
    There are hardly any linux viruses

    If you insist on having one for windows files on linux,

    Then install Clamav found in the Ubuntu Software Center and the gui frontend for it is clamtk also found in the Ubuntu Software Center.

    Check these Ubuntu documentations for more info

    security - Is it possible to configure Ubuntu as a software firewall?
  • user3215

    I have some systems running on Ubuntu in the private IP range . These systems are connected to a switch and the switch is connected to the ISP's modem.

    Neither the switch nor the modem support firewall options. I don't have any firewall device and I'm not willing to individually configure firewalls on all the systems (via gui/iptables).

    Is it possible to make an Ubuntu system into something like a software firewall, so that all the traffic/packets sent to or from the WAN(internet) would be allowed/denied based on its firewall rules?

    AFAIK almost every distribution can be set as a firewall. And also there are some distro specifically built for this purpose such as zentyal, clearos etc. 'zentyal' is based on Ubuntu while 'clearos' is based on Centos.
