Hi I have 2 ISP providers
wan1-20mbps
wan2-6mbps
I need to combine 2 WAN's and have speed on LAN 26Mb
How can I do it ?
I tried:

/ip address

/ip firewall nat
add chain=srcnat out-interface=WAN1 action=masquerade
add chain=srcnat out-interface=WAN2 action=masquerade
-----------------------------------------------------------------------
but no success
summary my speed 20mbps

I think you mark the connections in bad chains. Try to use prerouting chain instead of input and output.

/ip address
add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=Local
add address=192.168.1.2/24 network=192.168.1.0 broadcast=192.168.1.255 interface=WAN1
add address=192.168.2.2/24 network=192.168.2.0 broadcast=192.168.2.255 interface=WAN2


/ip firewall mangle
add chain=input in-interface=WAN1 action=mark-connection new-connection-mark=WAN1_conn
add chain=input in-interface=WAN2 action=mark-connection new-connection-mark=WAN2_conn

add chain=output connection-mark=WAN1_conn action=mark-routing new-routing-mark=to_WAN1
add chain=output connection-mark=WAN2_conn action=mark-routing new-routing-mark=to_WAN2


/ip route
add dst-address=0.0.0.0/0 gateway=192.168.1.1 routing-mark=to_WAN1
add dst-address=0.0.0.0/0 gateway=192.168.2.1 routing-mark=to_WAN2

/ip firewall nat
add chain=srcnat action=masquerade



Remember you haven't set default gateway & gateway for your local network.
here we go
First Mark Lan traffic with mangle rule
/ip firewall mangle
add chain=prerouting src-address=192.168.0.0/24 action=mark-routing new-routing-mark=local_trafic
Now add gateway for local trafic
/ip route
add dst-address=0.0.0.0/0 gateway="192.168.1.1,192.168.2.1,192.168.1.1,192.168.1.1" routing-mark=local_trafic
i have added 192.168.1.1 for 3 times & 192.168.2.1 for 1 time for automatic load balancing. as ur first gateway has 20Mbps & second has 6Mbps
now add default gateway, remember web proxy & dns requests goes through this gateway

/ip route
add dst-address=0.0.0.0/0 gateway=192.168.1.1 or 192.168.2.1 use which is more reliable


i hope this info will helpfull for you!

Just a note that if you load balance a 20mpbs connection and a 6mbps connection you don't combine the speeds. Those connections will be the same speed you'll just have the load spread among them. The only way to get a 26mbps connection out of that is interface bonding and that requires the ISPs cooperation because they have to bond on their end as well.

And that is not an easy job

thank you for help, guys
