[Solved] ASUS RT-AC68U DSL settings

The asus is a bridged DSL modem, the linksys with openwrt is the router? I am always confused about the actual terms.

Otherwise I am making progress with the Ultimate SQM settings: Layer_cake + DSCP marks - #444 by dlakelan thread, this solved many of the questions I had running advancedtomato whereas I begin to run to the end of the router config and needed scripts to further sharpen the qos. It was suggested I just run cake so I did :slight_smile:

I also have other questions like do I use

nat dual-dsthost ingress
nat dual-srchost

on all sqm instances - layer_cake and piece_of_cake? Do I swap the rules on the LAN sqm instance the same way I swap the up/down speed?


Are these set correctly?

My icmp is not functioning like the udp rule, it does when assigned mac but should this be

the WAN, LAN flipping egress and ingress values confuses me and @dlakelan explained but lol

##priority function creates a rule which isolates all traffic and defaults it, while prioritizing the egress udp packets from my pc on the lan

##firewall tcp/udp
## flush mangle table
iptables -t mangle -N dscp_mark
iptables -t mangle -F dscp_mark

iptables -t mangle -A FORWARD -j dscp_mark

iptables -t mangle -A FORWARD -p udp -m hashlimit  --hashlimit-name gaming --hashlimit-above 75/sec --hashlimit-burst 50 --hashlimit-mode srcip,srcport,dstip,dstport -j CONNMARK --set-mark 0x55

These two posts by @easyteacher are what I am trying to accomplish, if the router is able to distinguish lines this way using code, I would attempt it and monitor it like you said, but I need assistance it is very complex and written in a format I am not familiar with. First, what programs would I use to monitor this type of data, I see he drew some packets from the connections and while these values are important it is not critical and uncommon - we would like to simplify this ruleset. Like say I added a checkbox to OpenWrt that said "accelerate game packets" how would this be written in relation to @easyteacher 's code ?

Basically I want to build a virtual bullet train and as long as I have the hardware to accomplish this right now, I believe configuring it is the issue. If there are any other scripts you can think of which will assist or have suggestions to my rules - I only want a pipe running from my pc to the game servers which is big as possible and super slippery for the hit reg udp packets to transfer through.

My hope is to create a rule in iptables where layer cake is combined with dscp marked udp burst and length designed in a fashion related to @easyteacher 's packet identification

Your input is greatly appreciated, I am making more progress than I have in 2 years.
