That does not work for me. 

root at adb2go:/etc/config$ uci set firewall. at zone[1].mtu_fix='0'
root at adb2
go:/etc/config$ uci changes firewall
firewall.cfg06dc81.mtu_fix='0'
root@
adb2go:/etc/config$ uci commit firewall

I've changed the firewall config but no firewall reload afterwards,
/var/run/fw3.state stays the same (LEDE r2299).

a working example would help a lot.

Thanks!
