Most of the features described come from the fact that FreeBSD ships with OpenBSD's PF (among others). Why would you build it pick FreeBSD considering their PF version is very outdated ? I think going with an OpenBSD base would make more sense for a 'routing platform' as OpenBSD ships with various routing daemons and other network daemons that fit the description better (isakmpd/iked for IPsec with IKE/IKEv2, npppd for L2TP based tunnels ...). Obviously, you can install and use OpenVPN, pretty much any DNS implementation of your choosing to provide additional features. You also get a bunch of security features to mitigate attacks.[1] Most of them are enabled by default too, contrary to FreeBSD [2](though I have not checked if OPNsense enables them -- it makes sense to enable them, even more so on the network gateway) AFAIK, FreeBSD has better MP support than OpenBSD (though that is a work in progress), and more actively developed wireless stack. Are there any other motivations for using FreeBSD ?
