I have a load of really nice motherboards laying around and wanted to utilise at least one of them before they hit the skip! So I looked at creating a really HiEnd router with one.. PFSense fits every aspect of this job with ease and its free/cheap https://www.pfsense.org/download/ or you can purchase a pre configured hardware job… NICE!
check it out, put an old PC to good use, if you have a good managed switch laying around or from Ebay then happy days ! fantastic opportunity for some networking fun on the cheap..
Disclaimer never do anything I suggest i am nearly always wrong, misinformed, and know nothing about anything, period!
