I'm curious why you don't like OpenWRT?
replyI've found it to be the better choice for x86 hardware, because it performs so much better on older CPUs. FreeBSD has gotten better with driver support, but the Linux kernel in OWRT is just a better base to build off of.
not GP but I've found the install and upgrade experience for OpenWRT on larger machines is not great compared to the alternatives and normal Linux distros, everything is biased towards the use case of occasionally flashing/configuring little systems
replyI still use it though, can't complain in terms of actual routing/switching
I think OPNsense now supports ARM.
replyEdit: never mind. Not official images.
