Best settings for gaming QoS+DSCP

[-taz-]

Hi
Researching on IPTABLES
and Qos de Gargoyle, this is the best configuration I found, the only bad thing is that it does not give bufferbloat A +


make sure dns have a minimum TLL
and that MINRTT is active when the network is saturated









confirm if the game class is active




(WinSCP)


iptables -t mangle -A FORWARD -p tcp --tcp-flags ALL SYN,ACK -j TCPMSS --set-mss 1452

commands to restart Qos or Firewall
service firewall restart
service qos_gargoyle restart

stop Bwon network statistics "Performance Improvement"
/etc/init.d/bwmon_gargoyle stop
/etc/init.d/bwmon_gargoyle disable


iptables -t mangle -vnL

Thanks for sharing taz.

I have also been playing with iptables, and I am using this:

iptables -t mangle -N qos_plus

iptables -t mangle -A PREROUTING -j qos_plus
iptables -t mangle -A INPUT -j qos_plus
iptables -t mangle -A FORWARD -j qos_plus
iptables -t mangle -A OUTPUT -j qos_plus
iptables -t mangle -A POSTROUTING -j qos_plus

iptables -t mangle -I qos_plus -i eth0 -j DSCP --set-dscp-class CS0

iptables -t mangle -I qos_plus -p icmp -j DSCP --set-dscp-class CS6

iptables -t mangle -I qos_plus -d 192.168.1.142 -p udp -j DSCP --set-dscp-class CS4

iptables -t mangle -I qos_plus -s 192.168.1.142 -p udp -j DSCP --set-dscp-class CS4


It seems not to have a "correct" setting, but the best one for each person.

I think it's a good idea to include DSCP tags in the Qos Gargoyle interface, perhaps in place of the layer7 protocol.

I tried its configuration and it works almost the same as mine, but in my case my configuration is better for me.
eth0 does not work, the interface does not exist

iptables -t mangle -vnL

Did you test my settings?

You're right, it's just a different way of writing the rules.

eth0 is the wan interface.
Using the command ifconfig, the interface that displays your public ip (from internet) will be your wan interface. But maybe using the interface in the rule is not necessary.

I have tested your rules too, but for now the rules I use go well.

[-taz-]

where the Qos_plus command came from and what it does apart from the Qos gargoyle

[VanCleef]

qos_plus is a random name of your choice.

In this rule qos_plus means PRE / INP / FOR / OUT / POST at the same time.

Just an alternative to simplifying the rules.

EF should work nice in 'wired' game, radio dont know.

[VanCleef]

Hello

Based on the documentation, for wifi is also recommended CS4 for games.
https://tools.ietf.org/html/rfc8325
https://tools.ietf.org/id/draft-ietf-ts ... 11-05.html
I play over wifi and it's good.

But if the game flows better in voice class, like EF on cable, it will be CS6 on wifi.

[VanCleef]

I am also testing better MTU values, and it looks like xbox was right to have MTU 1480 as default.
Games are more responsive on my ps4.

The mtu in gargoyle interface i do not change.

If you play on PC and have trouble for open sites after the change, you can use these commands to set mtu:

iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1440

for a specific ip:
iptables -A FORWARD -s 192.168.1.142 -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1440

This site shows the current mtu:
