It never matched my requirements and I never saw a reason not to use
OpenWrt's firewall package. I've heard some vague myths about OpenWrt's
firewall not working well with some of the routing protocols used in
libremesh, but all attempts to reproduce that or inquire what the
problem was or is remained without substancial results.
I guess there are some historic reasons for some people to still
hestitate using OpenWrt's firewall (ie. fw3 nowadays), maybe some bug
which has long been resolved or simply not (auto-)adding the rules
needed to also run routing protocols on the WAN interface (which I've
fixed some years ago).
