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.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) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 1422 packets, 326K bytes) pkts bytes target prot opt in out source destination
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.
