Ubuntu Linux and firewalling and dual NIC's

[J. L.]

Hi!

Of course Ubuntu, just like more or less any other Linux distro, _can_
be used for firewalling but since You had asked for advice i'd
_strongly_ suggest You'd better take a look at one of the following
specialized "distros" with pfSense and OPNsense being based on FreeBSD
and not Linux:

http://www.ipfire.org/
https://www.fli4l.de/
https://www.sophos.com/en-us/lp/utm-upgrades.aspx (formerly knowna as
Astaro Linux)
https://www.pfsense.org/
https://opnsense.org/

Among some others Endian, Gibraltar, IPCop and Smoothwall seem not to be
really actively maintained any longer. But that depends on one's point
of view! ;-)

Lots of luck!
