RouterOS Load Balancing

Tässä ohjeessa tehdään kahden WAN portin kuormantasaus. Käytössämme on RB951-2HnD (RouterOS 6.28) reititin ja kaksi WAN yhteyttä. Suosittelemme käyttämään kahta samanlaista WAN yhteyttä.

 wan1: 192.168.10.1
 wan2: 192.168.20.1
 bridge-local: 192.168.88.1

bridge-local on verkkosilta.

Määritetään staattiset IP-osoitteet:

 /ip address
     add address 192.168.88.1/24 interface=bridge-local
     add address 192.168.10.1/24 interface=wan1
     add address 192.168.20.1/24 interface=wan2

Konfiguroidaan palomuuri (Mangle)

 /ip firewall mangle
     add chain=input in-interface=wan1 action=mark-connection new-connection-mark=wan1-con
     add chain=input in-interface=wan2 action=mark-connection new-connection-mark=wan2-con
    
    add chain=output connection-mark=wan1-con action=mark-routing new-routing-mark=to-wan1
    add chain=output connection-mark=wan2-con action=mark-routing new-routing-mark=to-wan2
   
    add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/0 action=mark connection new-connection-mark=wan1-con passthrough=yes
    add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/1 action=mark-connection new-connection-mark=wan2-con passthrough=yes
    
    add chain=prerouting connection-mark=wan1-con in-interface=Local action=mark-routing new-routing-mark=to_WAN1
    add chain=prerouting connection-mark=wan2-con in-interface=Local action=mark-routing new-routing-mark=to_WAN2

Konfiguroidaan reititys

 /ip route
    add dst-address=0.0.0.0/0 gateway=192.168.10.1 routing-mark=to-wan1 check-gateway=ping
    add dst-address=0.0.0.0/0 gateway=192.168.20.1 routing-mark=to-wan2 check-gateway=ping

Konfigoroi NAT

 /ip firewall nat
    add chain=srcnat out-interface=wan1 action=masquerade
    add chain=srcnat out-interface=wan2 action=masquerade
