Re: [LARTC] HTB metro/international

[George Alexandru Dragoi <waruiinu@gmail.com>]

http://metropolitana.loginet.ro/ and reat that stuff, or

you can try to diferentiate metro/interfor for download asking your
ISP if they set a specific DSCP for it. For upload limitting, i add
routes for all metropolitan ips (or bgp does it automatically), and
the default route has a special realm. You can then match the realm in
FORWARD or POSTROUTING chain in mangle and set a mark to those
packets, then mark every ip with a different mark. ex:

eth0 - your ISP (let's say GTS)
eth1 - your lan 192.168.1.0/24

Gts uses 32 value as dscp for international traffic (0x20)

tc qdisc add dev eth1 root handle 1: htb r2q 1

tc class add dev eth1 parent 1: classid 1:999 htb rate 90mbit
tc class add dev eth1 parent 1:999 classid 1:1 htb rate 2mbit
tc class add dev eth1 parent 1:999 classid 1:998 htb rate 80mbit
#client with ip 192.168.1.2 has at most 1mbit for metro, 128kbit for external
tc class add dev eth1 parent 1:1 classid 1:2 htb rate 256kbit #Your
total external bandwith

tc class add dev eth1 parent 1:1 classid 1:11 htb rate 12kbit ceil
1mbit #metro for client 1
tc class add dev eth1 parent 1:2 classid 1:21 htb rate 8kbit ceil
128kbit #external for first client

FIlters are:

tc filter add dev eth1 parent 1: protocol ip prio 1 u32 match ip dst
192.168.1.2/32 match tos 0x80 0xfc classid 1:21
tc filter add dev eth1 parent 1: protocol ip prio 2 u32 match ip dst
192.168.1.2/32 classid 1:11

A global filter for lan traffic would be:
tc filter add dev eth1 parent 1: protocol ip prio 0 u32 math ip src
192.168.1.1/32 classid 1:998

For upload, after you make a script to add all metropolitan routes:

ip ro add $prefix via $isp_gw

and the default route would be:

ip ro add default via $isp_gw realm 6

Check /etc/iproute2/rt_realms

iptables -t mangle -N metro-up
iptables -t mangle -N ext-up
iptables -t mangle -A FORWARD -o eth0 -m realm --realm 6 -j ext-up
iptables -t mangle -A FORWARD -o eth0 -m realm --realm 6 -j ACCEPT
iptables -t mangle -A FORWARD -o eth0 -j metro-up

iptables -t mangle -A ext-up -s 192.168.1.2 -j MARK --set-mark 0x21
iptables -t mangle -A metro-up -s 192.168.1.2 -j MARK --set-mark 0x11

add classes similar to eth1

tc filter add dev eth0 parent 1: protocol ip prio 1 handle 0x21 fw classid 1:21
tc filter add dev eth0 parent 1: protocol ip prio 1 handle 0x11 fw classid 1:11
