I noticed there is a note in LEDE Documentation which says that disabling firewall's connection tracking can speed up routing and save memory. So I tried to disable it but that didn't work. Could someone tell me how to do it?
Thanks in advance.
What I did
I followed the guide and tried disabling it by specifying 'option conntrack 0' in /etc/config/firewall.
# cat /etc/config/firewall
[...]
config zone
option name awlan
list network 'awlan'
option conntrack 0
option input REJECT
option output ACCEPT
option forward REJECT
[...]
And then, I proceeded to reload the configuration but it says the option conntrack is unknown.
# /etc/init.d/firewall reload
Warning: Option @zone[0].conntrack is unknown
[...]
As expected, there seems to be no firewall rules regarding connection tracking.
# iptables -t raw -L -vn
Chain PREROUTING (policy ACCEPT 1587 packets, 251K bytes)

Hardware and Software
I don't know if this clarifies the issue, but I tried LEDE 17.01.2 on WZR-300HP (Buffalo) and WZR-HP-G450H (Buffalo) and both of which didn't work.
