Ubuntu Linux and firewalling and dual NIC's

[Brandon Tomlinson]

Howdy,

It totally can. This will work by just specifying the interface name.

Example: `ufw allow in on eth0 to any port 80 proto tcp` if you wanted to run a web server.

Hope that answers your question.

-Brandon, out!

Subject: Ubuntu Linux and firewalling and dual NIC's

Hello.

I have a firewall/gateway computer, that has two network cards, and we are soon to change from ADSL to the (Australian) soupy-doupy NBN thing with supposedly higher data transmission speed capabilities, which means a new modem/router thing with which to interface, and so, new settings (or so, I expect), which means, in the context of the status of the firewall/gateway computer, replacing the operating system and firewall software.

I have thus far, used Ubuntu Linux only as a workstation operating system, which does not involve two network interfaces; two NIC's, and so I need to know whether Ubuntu can be used on the firewall/gateway computer, running two NIC's on the same computer.

Please advise.

Thank you in anticipation.
