Title: Help with installing the thing on a PC (dual boot)
Post by: N00byGeek on February 13, 2020, 05:05:51 pm: Hi,
please forgive my nooby question but I did´t get it from the tutorial past the USB media creation.
I want to install OPNsense on a notebook using dual boot Ubuntu/Win10 (please no advices to virtualizing Win in Ubuntu, as it has not a strong hardware).

As i understand, the OPNsense image needs to install first on a HDD, but I do not know how to proceed afterwards. Can I simply run a Win10 installation process from an USB stick, after I installed OPNsense (and partitioned the HDD)? Afterwards doing the same for Ubuntu.

In case Win 10 install is not supported, I am fine with doing only with Ubuntu (so no dual boot).

p.s.: I prefer the MBR / BIOS type of install.

Thank you very much for a hint

Just a simple question: is OPNsense a firewall to protect other operating systems of a (home) computer, or is it a software intended for servers only?

Thanks :-)

It is neither :)

OPNsense is an appliance based on hardenedbsd which turns a computer into a network firewall. https://www.cisco.com/c/en/us/products/security/firewalls/what-is-a-firewall.html

Host firewalls cannot offer the same level of security, since they share the system that they are meant to be protecting. Any malware can alter or disable the host firewall but it will have a much harder job tampering with the network firewall, especially if you reduce the attack surface by minimising the services that OPNsense offers, such as DNS, web proxy, etc.

Thank you

Spot on, that's exactly how to use OPNsense 8)

For home use, it can be relatively low spec. Check out the hardware requirements: https://wiki.opnsense.org/manual/hardware.html

Thank you. ECC RAM because of security or stability? ;)

Ah, so now I got the primary mode of operation :) Sounds feasibly. With a throughput say 8-15 Mbps, I see no problem in most scenarios. And with the recent refreshment of desktop CPU market, might be even more interesting 8)
Thank you

Long live open-source movement! :-)
