Hi all.
I would like to solve a mystery in a load balance script cause i really cant understand.
according to this
The mangle rule set for distributing the traffic evenly to both links
/ip firewall mangle
add chain=input in-interface=WAN1 action=mark-connection new-connection-mark=WAN1_mark
add chain=input in-interface=WAN2 action=mark-connection new-connection-mark=WAN2_mark
add chain=output connection-mark=WAN1_mark action=mark-routing new-routing-mark=to_ISP1
add chain=output connection-mark=WAN2_mark action=mark-routing new-routing-mark=to_ISP2
add chain=prerouting dst-address=192.168.1.0/24 action=accept in-interface=Local
add chain=prerouting dst-address=192.168.2.0/24 action=accept in-interface=Local
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_mark 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_mark passthrough=yes
add chain=prerouting connection-mark=WAN1_mark in-interface=Local action=mark-routing new-routing-mark=to_ISP1
add chain=prerouting connection-mark=WAN2_mark in-interface=Local action=mark-routing new-routing-mark=to_ISP2
FAIL OVER WITH ROUTING the wan Links
For checking the remote address i am using these hosts
8.8.8.8 Google-DNS host1A
72.30.2.43 Yahoo host1B
8.8.4.4 Google-DNS host2A
199.59.148.82 Twitter host2B
first we need routes to our checking hosts:
/ip route
add dst-address=8.8.8.8 gateway=192.168.1.1 scope=10
add dst-address=72.30.2.43 gateway=192.168.1.1 scope=10
add dst-address=8.8.4.4 gateway=192.168.2.1 scope=10
add dst-address=199.59.148.82 gateway=192.168.2.1 scope=10
Then, let’s create destinations to “virtual” hops to use in further routes. I’m using 10.1.1.1 and 10.2.2.2 as an example:
/ip route
add dst-address=10.1.1.1 gateway=8.8.4.4 scope=10 target-scope=10 check-gateway=ping
add dst-address=10.1.1.1 gateway=72.30.2.43 scope=10 target-scope=10 check-gateway=ping
add dst-address=10.2.2.2 gateway=8.8.8.8 scope=10 target-scope=10 check-gateway=ping
add dst-address=10.2.2.2 gateway=199.59.148.82 scope=10 target-scope=10 check-gateway=ping
And now we may add default routes for clients:
/ip route
add distance=1 gateway=10.1.1.1 routing-mark=to_ISP1
add distance=2 gateway=10.2.2.2 routing-mark=to_ISP1
add distance=1 gateway=10.2.2.2 routing-mark=to_ISP2
add distance=2 gateway=10.1.1.1 routing-mark=to_ISP2
And masquerade both wan interfaces
/ip firewall nat
add chain=srcnat out-interface=WAN1 action=masquerade
add chain=srcnat out-interface=WAN2 action=masquerade
How do those virtual hops work? because when i ping 10.1.1.1 or 10.2.2.2 nothing happens
also in ip routes they show as unreachable.
Is this normal behaviour?
Thanks
