Is there any manual or tutorial for MikroTik V3 LoadBalancing

thanks for the info!!!

you may use load balancing for 2.9 - there's no difference in principle

But which is the best method of loadbalancing from the example of wiki.

I have two Lines.
VSAT : 512 Kbps
Leased Line : 1 Mbps:

Now i dont want round robin, I want to Balance 1:2, How to do that, Coz i have tried with the wiki example, The VSAT is getting full but NOT able to use the bandwidth from Leased line.

Again In LAN we are facing slow speed issue...

But which is the best method of loadbalancing from the example of wiki.

yup.. i have the same questions with ashish.

it would be nice if mikrotik release an official tutorial with an example about load balancing

Well, I've already try but it wont works.... Like thiz one http://wiki.mikrotik.com/wiki/Load_Balancing it won't works on MikroTik V3, Is there any additional information that miss for Version 3

You can try what I am working on right now.

network 214.0.0.0/24 I split in 2 LAN1 214.0.0.0-127 and LAN2 214.0.0.255 config is as follows:

/ip firewall mangle

add action=mark-routing chain=prerouting comment="" disabled=no dst-address=0.0.0.0/0 new-routing-mark=LAN1 \
passthrough=yes src-address=214.0.0.0/25
add action=mark-routing chain=prerouting comment="" disabled=no dst-address=0.0.0.0/0 new-routing-mark=LAN2 \
passthrough=yes src-address=214.0.0.128/25

/ip route

add comment="Clearwire" disabled=no distance=1 dst-address=0.0.0.0/0 gateway=88.147.15.2 routing-mark=LAN2 scope=30 target-scope=10

add comment="Telenet" disabled=no distance=1 dst-address=0.0.0.0/0 gateway=213.0.0.1 routing-mark=LAN1 scope=30 target-scope=10

if you want to see the differnece between the nth parameter try a voice or video conversation u'll find it there espcially at peak time

Regards,

Well, thank you very much for the config but that's not what i needed, i want the configuration like the one from wiki. mikrotik because i ussually doin some large download, the bandwidth become one while the download process like the wiki state.

its meant for ppl who want to split bandwidth not combine like your case

its meant for ppl who want to split bandwidth not combine like your case

Yup!!! Is there anyone can help me, the refer or something else???

I'm found it!!! and it's really works 100% run..........

Hi guys,

I have been in your position before and have worked through to learn all the lessons the hard way.

You have these options for load balancing:

ECMP
Round Robin
Policy Based Routing

Part of the problem for you and for me is that your internet supplies are not matched. 1 is a high latency vsat of only half the bandwidth of the other lower latency bandwidth.

Eventually you will come to realise that Policy Based Routing is the most suitable solution for you.

This url spells it all out http://wiki.mikrotik.com/wiki/Per-Traff ... _Balancing

Enjoy!

Yeah.. it's true what you say!! But for some reason I don't like policy based routing, when one of the connection is down we should manually change it or maybe you put another script to make it run automatic.
Different with full bandwidth, when one connection is down, the another one will backup the connection till the the one has been Up. off course that each configuration has weaknesses.

instead of

add dst-address=0.0.0.0/0 gateway=10.0.1.1 scope=255 target-scope=10 routing-mark="WAN - 01" comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=10.0.2.1 scope=255 target-scope=10 routing-mark="WAN - 02" comment="" disabled=no

use something like

add dst-address=0.0.0.0/0 gateway=10.0.1.1 scope=255 target-scope=10 routing-mark="WAN - 01" comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=10.0.2.1 scope=255 target-scope=10 routing-mark="WAN - 01" comment="" disabled=no distance=100
add dst-address=0.0.0.0/0 gateway=10.0.2.1 scope=255 target-scope=10 routing-mark="WAN - 02" comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=10.0.1.1 scope=255 target-scope=10 routing-mark="WAN - 02" comment="" disabled=no distance=100

and you may use 'check-gateway' option

Did you say you got the load balancing working where it will combine bandwidth during download? If so what would you mind posting your config?
thanks
Kenny

Config for which one? Firewall, NAT, Mangle or routing? Like the chupaka said that the basic it's not so far but the problem lays on NAT & NTH in Mangle....
If you use hotspot it preferable to use masquerade instead of src-nat and the NTH follow the sum of connection you used!

I used the NTH 2,1 and 2,2 for my connection but i don't know why there still some delay between 2 connection!! Hmmm how can i say.... I'm still don't really understand the NTH especially for the best configuration for each connection!

Using the NTH parameters (remind this is changed a little in 3.x version) divides only the connections over the two (or more) WAN links. I can happen easily that one WAN gets more data traffic then the other just because one connection group sees more heavy users then the other.
the bigger the LAN network and amount of users, the more even the bandwidth will be spread.

If you have un-equal capacity WAN links then work the nth a bit up. Like 1x4mb WAN ¨A¨and 1x2Mb WAN ¨B¨. you can make every first connection to go to ¨A¨, every second to ¨B¨ and every third to ¨A¨ again.

Load balancing where packages are evenly distributed over two lines will see problems in case of https traffic and possibly others where the user-PC likes to see the packages coming from the same WAN network as the others in the same connection...

Well, instead of using 'Nth', I prefer using 'Random': at first, there's no difference if you have a lot of users (if you have a little - just forget about load balancing =) ), and second - you may smoothly change bandwidth ratio over each connection

use something like

add dst-address=0.0.0.0/0 gateway=10.0.1.1 scope=255 target-scope=10 routing-mark="WAN - 01" comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=10.0.2.1 scope=255 target-scope=10 routing-mark="WAN - 01" comment="" disabled=no distance=100
add dst-address=0.0.0.0/0 gateway=10.0.2.1 scope=255 target-scope=10 routing-mark="WAN - 02" comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=10.0.1.1 scope=255 target-scope=10 routing-mark="WAN - 02" comment="" disabled=no distance=100

What's the effect for the network?

Well, depends on your mangle rules.

And it only works if your gateways are the ADSL modems. (If not, you have a backhaul in between, and the backhaul is up but the modem or WAN is down? Then the gateway stays in force but it is a dead end gateway.)

well, netwatch will help

Hi guys, I need to bypass some traffic... like rapidshare traffic and put it on one specific gateway... Can anybody help me?

BUT there's no imformation about loadbalancing using "Random" ,would you tell me the detail. I ilhave tried it so long.but it
still have problem. i have 5 ADSL to loadblaning. looking for your help. thank you so much

for 5 lines, 'random=' values (to spread all equally) should be: 20, 25, 33, 50, and in the last rule there should not be 'random' - it will match all residual packets. also all rules, that distribute your packets via uplink lines, should have passthrough=no, and connection-type=new, and above you should add rules, that will forward already marked connections to corresponding lines

thank you for your help, Now I know how to make the "random" values . but i'm a rookie in MT. would you mind show me the all the rules or correct my rules above in (/ip firewall mangle) using random to loadbalancing 5 ADSL ?I still don't know which rule should have passthrough=no or add connecton= new also I want to know what rules should be add. I tried for many times but it still not to work. i also want to know is it necessary to mark "dst-port 443" in order to login in Network Bank.

thank you so much

Thx Chupaka, that was a great hint on how Random works! We use Nth extensively for src-nat'ting. We have 4000+ users, who are distributed to 252 different groups using Nth. Each group is the src-nat'ted through different Real IPs. The problem we face is, the 252 groups are not evenly loaded, meaning the number of IPs in each group keep decreasing as Nth values keep ascending, say first 10% groups have 10 - 12 each, where the last 10% has 1 - 2 each.

An excerpt from my config is (for the 12th group):

add action=mark-connection chain=prerouting comment="" disabled=no \
new-connection-mark=cn012 passthrough=yes src-address-list=cn012
add action=mark-routing chain=prerouting comment="" disabled=no \
new-routing-mark=cn012 passthrough=no src-address-list=cn012
add action=mark-connection chain=prerouting comment="" connection-state=new \
disabled=no new-connection-mark=cn012 nth=252,12 passthrough=yes \
src-address=192.168.0.0/18
add action=add-src-to-address-list address-list=cn012 address-list-timeout=8h \
chain=prerouting comment="" connection-mark=cn012 disabled=no \
src-address=192.168.0.0/18
add action=mark-routing chain=prerouting comment="" connection-mark=cn012 \
disabled=no new-routing-mark=cn012 passthrough=no \
src-address=192.168.0.0/18
add action=mark-connection chain=prerouting comment="" connection-state=new \
disabled=no new-connection-mark=cn012 nth=252,12 passthrough=yes \
src-address=10.0.0.0/14
add action=add-src-to-address-list address-list=cn012 address-list-timeout=8h \
chain=prerouting comment="" connection-mark=cn012 disabled=no \
src-address=10.0.0.0/14
add action=mark-routing chain=prerouting comment="" connection-mark=cn012 \
disabled=no new-routing-mark=cn012 passthrough=no src-address=10.0.0.0/14

My guess is that the part of the problem could be we use two different IP address blocks in the private IP range (one /18 and one /14), which is throwing off the Nth counter. But, this assumes that there is only One Nth counter for the whole router.

Can someone shed some light on this? Is it even advisable to use such a large number of Nth rules?
