MikroTik Load Balancing

Condition: ISP where we work as an administrator to use more than one gateway to connect to the Internet. Everything must be able to serve the upstream & downstream service. Because the case would be different if one of them can only serve downstream, for example when using VSAT DVB One-way.
For this case in the example ISP has 2 lines to the Internet. One use access DSL (256 Kbps) and others use Wireless (512 Kbps). With DSL usage ratio: Wireless = 1:2.

What will be done:

1. Using all the available gateway channels with load-balancing techniques.
2. Making one as a back-up with fail-over technique.

OK, let's just get started experiments:

1. IP address for access to the LAN:
> / Ip address add address = 192.168.0.1/28 interface = LAN
IP address for access to DSL lines:
> / Ip address add address = 10.32.57.253/29 interface = DSL
IP address for access to lines Wireless:
> / Ip address add address = 10.9.8.2/29 interface = WIRELESS
Specify the gateway and the ratio of each:
> / Ip route add gateway = 10.32.57.254,10.9.8.1,10.9.8.1

2. In the case for fail-over technique. Assumed to be the main route through Wireless with DSL lines as a back-up if the main line were impassable. To check whether the main line can be passed or not, use the ping command.
> / Ip firewall mangle add chain = prerouting src-address = 192.168.0.0/28 action = mark-routing new-routing-mark = SUBNET1-RM
> / Ip route add gateway = 10.9.8.1 routing-mark = SUBNET1-RM check-gateway = ping
> / Ip route add gateway = 10.32.57.254

3. Good Luck!!

================================================== =====================================

seemed to use the proxy to be able to "load balancing" stay put 3 interface,

interface A for Speedy1, eg IP 192.168.1.1
interface B for Speedy2, eg IP 192.168.2.1
C interface to the LAN, for example IP 10.10.10.0/24


in mikrotik config like this:

> / Ip address add address = 10.10.10.0/24 interface = LAN
IP address for SpeedyA:
> / Ip address add address = 192.168.1.1/32 interface = SpeedyA
IP address for SpeedyB:
> / Ip address add address = 192.168.2.1/32 interface = SpeedyB
Next we specify the gateway and priorities:
> / Ip route add gateway = 192.168.1.1,192.168.2.1,192.168.2.1

Could also be added config for failover, jd example is one of the main speedy reply can die instantly using only speedy path,

> / Ip firewall mangle add chain = prerouting src-address = 10.10.10.0/24 action = mark-routing new-routing-mark = RM-SPEEDY
> / Ip route add gateway = 192.168.2.1 routing-mark = rm-speedyB check-gateway = ping
> / Ip route add gateway = 192.168.1.1


Or the other alternative is, we divide the traffic into two lanes speedy network group based on our LAN,

Our IP settings on each "proxy interface,

/ ip address add address 192.168.1.1/32 interface speedyA
/ ip address add address 192.168.2.1/32 interface speedyB
/ ip address add address 10.10.10.1/24 interface LAN

Next we try to network into Group 2

add chain = prerouting action = mark-connection src-address 10.10.10.0/25 new-routing-mark = Group-A
add chain = prerouting action = mark-connection src-address 10.10.10.128/25 new-routing-mark = Group-B

then we set the default gateway of each group

/ ip route add gateway = 192.168.1.1 routing-mark = Group-A
/ ip route add gateway = 192.168.2.1 routing-mark = Group-B

Make sure also we've set the NAT on our network

/ ip firewall nat add chain = srcnat src-address 10.10.10.0/24 action = masquerade

================================================== ==============================
Using 3 etrernet card

ether1 ==> wireless
ether2 ==> speedy
ethet3 ==> Lan

mikrotik command:
/ ip address add address 202.152.74.1/32 interface ether1
/ ip address add address 192.168.1.2/32 interface ether2
/ ip address add address 192.168.10.1/24 interface ether3

Ip divide into 2 Group

add chain = prerouting action = mark-connection src-address 192.168.10.0/25 new-routing-mark = Group-A
add chain = prerouting action = mark-connection src-address 192.168.10.128/25 new-routing-mark = Group-B

Default each Group

Group-A = 192.168.10.0/25 default 192.168.1.1

Group-B = 192.168.10.128/25 default 202.152.74.128

mikrotik command:

/ ip route add gateway = 192.168.1.1 routing-mark = Group-A
/ ip route add gateway = 202.152.74.128 routing-mark = Group-B

Local ip nat

192.168.10.0/24 ==> masquerade

mikrotik command:
/ ip firewall nat add chain = srcnat src-address 192.168.10.0/24 action = masquerade

================================================== ================================
ip route add dst-address = 0.0.0.0 / 0 gateway = 192.168.1.1 check-gateway = ping
ip route add dst-address = 0.0.0.0 / 0 gateway = 10.0.148.254 check-gateway = ping

Where 192.168.1.1 ADSL router & gateway 10.0.148.254 RT / RW-net use 2.4GHz so it's just ..
check the gateway using ping so if the gateway down
direct switch. If not directly on ya down 2 at the same time, wealthy hell load balancing

I just happened to add a parameter distance = 2 at the gateway RT / RW-net can be a lower priority ..

Firewall / NAT makes two seeds for each gateway

for easy client
add a default route IP-ether-mikrotik

PC / Router mikrotik I operate a LAN card 3
2 to the ADSL modem, LAN 1 toward the
clients are directed to the ethernet LAN gateway proxy only

Good luck and Good luck .... ...
