Basic Setup

This page will tak about how to make QUEUE TREE in RouterOS that with Masquerading for more than two interfaces. It's for sharing internet connection among users on each interfacess. In manual this possibility isn't writted.

First, let's set the basic setting first. I'm using a machine with 3 or more network interfaces:

[admin@instaler] > in pr
#    NAME       TYPE    RX-RATE    TX-RATE    MTU  
0  R public     ether   0          0          1500 
1  R wifi1      wlan    0          0          1500
2  R wifi2      wlan    0          0          1500
3  R wifi3      wlan    0          0          1500

And this is the IP Addresses for each interface:

[admin@instaler] > ip ad pr
Flags: X - disabled, I - invalid, D - dynamic 
#  ADDRESS           NETWORK      BROADCAST      INTERFACE
0  10.20.1.0/24      10.20.1.0    10.20.1.255    public   
1  10.10.2.0/24      10.10.2.0    10.10.2.255    wifi1
2  10.10.3.0/24      10.10.3.0    10.10.3.255    wifi2
3  10.10.4.0/24      10.10.4.0    10.10.4.255    wifi3

On the public you can add NAT or proxy if you want.

Mangle Setup

And now is the most important part in this case.

As we will make Queue for uplink and downlink traffic, we need packet-marks. In this example, we use "test-up" for uplink traffic, and "test-down" for downlink traffic.

For uplink traffic, it's quite simple. We need only one rule, using SRC-ADDRESS and IN-INTERFACE parameters, and using PREROUTING chain. Rule number #0.

But for downlink, we have to make sevaral rules. As we use masquerading, we need Connection Mark, named as "test-conn". Rule no #1.

Then we have to make 2 more rules. First rule is for non-HTTP connection / direct connection. We use chain forward, as the data traveling through the router. Rule no #2.

The second rule is for data coming from web-proxy to the client. We use OUTPUT chain, as the data coming from internal process in the router itself. Rule no #3.

For both rules (no #2 and #3) we named it "test-down".

Please be aware, we use passthrough only for connection mark (rule no #1).

[admin@instaler] ip firewall mangle> print
Flags: X - disabled, I - invalid, D - dynamic 
0   chain=forward src-address=10.10.2.10 
    action=mark-connection new-connection-mark=users-10U passthrough=yes 

1   chain=forward dst-address=10.10.2.10 
    action=mark-connection new-connection-mark=users-10D passthrough=yes 

2   chain=forward connection-mark=users-10U action=mark-packet 
    new-packet-mark=10 passthrough=yes 

3   chain=forward connection-mark=users-10D action=mark-packet 
    new-packet-mark=10 passthrough=yes 

4   chain=forward src-address=10.10.2.10 
    action=mark-connection new-connection-mark=users-10U passthrough=yes 

5   chain=forward dst-address=10.10.2.10 
    action=mark-connection new-connection-mark=users-10D passthrough=yes 

6   chain=forward connection-mark=users-10U action=mark-packet 
    new-packet-mark=10 passthrough=yes 

7   chain=forward connection-mark=users-10D action=mark-packet 
    new-packet-mark=10 passthrough=yes 

98  chain=forward src-address=10.10.0.0/16 dst-address=10.10.0.0/16 
    action=mark-connection new-connection-mark=users-lokal passthrough=yes 

99  chain=forward connection-mark=users-lokal action=mark-packet 
    new-packet-mark=lokalTrafic passthrough=yes 

Queue Tree Setup

And now, the queue tree setting. We need one rule for downlink and one rule for uplink. Be careful when choosing the parent. for downlink traffic, we use parent "lan", the interface name for local network. And for uplink, we are using parent "global-in".

[admin@instaler] > queue tree pr
Flags: X - disabled, I - invalid 
0   name="downstream" parent=lan packet-mark=test-down 
    limit-at=32000 queue=default priority=8 
    max-limit=32000 burst-limit=0 
    burst-threshold=0 burst-time=0s 

1   name="upstream" parent=global-in 
    packet-mark=test-up limit-at=32000 
    queue=default priority=8 
    max-limit=32000 burst-limit=0 
    burst-threshold=0 burst-time=0s

You can use those mangle also with PCQ.
