Pro tip: buy a computer for and make it into a router .. There are some great cheap fanless machines out there (servethehome has reviews)...

You could also just use an old pc...

For software opnsense, pfsense, openbsd, freebsd, Linux (openwrt could be used too if you want embedded)

It is a pain to start ... But satisfying when it works :)
