Installed latest OpenWRT build, enabled HW NAT. Under last LEDE build it was working near good, able to use gigabit wan speed but cant drop old connections properly BUT working. Now it drops, but only 70MB/s and got some errors too with disconnections from PPPoE randomly, not when using full speed.
First half with SW NAT, maxed only 44MB/s , second half with HW NAT enabled (my current connection is 500/200Mbps but soon get up to 1Gbps)

Thank you for hard support. Installed Padavan and using without any problem. I will recommend it to my friends too, avoid OpenWRT far far away...
