any better code?

The first one is mine. It’s modified to work with Hotspot networks. If you’re using Hotspots, the second one won’t work for you. If you’re not using Hotspots, the first one will not work for you so choose the second one, though I would replace the masquerade NAT rules with specific srcnat entries explicitly choosing a public IP to NAT to. Masquerade ‘automagically’ works and that’s not a good thing with multiple WAN links.

If you end up choosing option two, add this:

add action=accept chain=prerouting disabled=no dst-address=192.168.0.5/24 src-address=192.168.100.1/24
add action=accept chain=prerouting disabled=no dst-address=192.168.1.5/24 src-address=192.168.100.1/24

at the top of the prerouting chain rules, though. Reasons for that are explained in the PCC wiki entry.

I am using the first one because I use Hotspot

there seem error in the red bold lines

add action=mark-routing chain=prerouting connection-mark=outside2_connection disabled=no new-routing-mark=to_outside2 passthrough=yes src-address-list=Local_NAT_Networks

the error is bad argument name per-connection-classifier
I have 3.22 routerOS

5

http://wiki.mikrotik.com/wiki/PCC

Notes
PCC is available in RouterOS since v3.24. This option was introduced to address configuration issues with load balancing over multiple gateways with masquerade

6

Then what is the solution for load balancing Hotspot for version 3.22(IS the upgrade from 3.22 to 3.30 free. Do you recommed to upgrade to 4.2)

Note: all line in your code has been excuted expect the lines in red

7

Now I have 1 active ADSL line(outside2) and I upgrade RouterOS to 4.2 but when I added the lines in red, the internet stop working. Does the code require that both lines are working
