MikroTik

Dear Concern,

I am kawsar from BD and really new on this field. I don't know more about mikrotik. If anyone could help me I will be glade.

My exceptation-

I have to WAN connection on same mikrotik [CCR-1009-1S-1S+]. ether1 and ether2. I have outpur LAN on ether6. I have WAN1=25 Mbps and WAN2=20 Mbps bandwidth. I made PCC load balance and Its not working properly. When I start loadbalance, all of my customer makes complain to me that the NET is really very slow. Eventhough sometimes GMAIL is not opened. When I stop loadblance its works fine. Customer also don't have any problem.

Now lets think about another thing.

I have two WAN port in my Mikrotik CCR-1009-1S-1S+. Example: WAN1 and WAN2.

I have one LAN port named LOCAL.

I have 4 IP block for my local users. Example: 192.168.0.0/24, 192.168.1.0/24, 192.168.2.0/24, 192.168.3.0/24.

Now I want I will pass my user by two WAN port. Example: By WAN1 port I will pass 192.168.0.0/24, 192.168.1.0/24 users block and by WAN2 I will pass 192.168.2.0/24, 192.168.3.0/24. 

Could anyone help me to solve this issue and is that possible really?

Thanks

If load balancing gives problems, then you may have problems with simple policy routing because they're basically the same thing. Load balancing should be the best way to go - check the archives for MUM2012 USA - there were two good presentations on load balancing that year.

Thanks Sir,
I got the script of MUM 2012. I applied it. same script I have used. Just changed the interface and IP address. I am getting bandwidth from WAN1, not getting bandwidth from WAN2 links. do you have any solution?
Thanks in advance.
Step-1 [2-3]
/ip firewall mangle
add action=mark-connection chain=prerouting connection-mark=no-mark disabled=no in-interface=WAN1 new-connection-mark=WAN1 passthrough=yes
add action=mark-connection chain=prerouting connection-mark=no-mark disabled=no in-interface=WAN2 new-connection-mark=WAN2 passthrough=yes

Step-2 [4-5]
add action=mark-routing chain=output connection-mark=WAN1 disabled=no new-routing-mark=to_WAN1 passthrough=yes
add action=mark-routing chain=output connection-mark=WAN2 disabled=no new-routing-mark=to_WAN2 passthrough=yes

Step-3 [6-7]
/ip firewall mangle
add action=accept chain=prerouting disabled=no dst-address=172.17.0.0/30
add action=accept chain=prerouting disabled=no dst-address=172.18.0.0/30


Step-4 [8-9]
/ip firewall mangle
add action=mark-connection chain=prerouting connection-mark=no-mark disabled=no dst-address-type=!local \
in-interface=LOCAL new-connection-mark=WAN1 passthrough=yes per-connection-classifier=both-addresses:2/0

add action=mark-connection chain=prerouting connection-mark=no-mark disabled=no dst-address-type=!local \
in-interface=LOCAL new-connection-mark=WAN2 passthrough=yes per-connection-classifier=both-addresses:2/1


Step-5 [10-11]
/ip firewall mangle
add action=mark-routing chain=prerouting connection-mark=WAN1 disabled=no in-interface=LOCAL new-routing-mark=to_WAN1 passthrough=yes
add action=mark-routing chain=prerouting connection-mark=WAN2 disabled=no in-interface=LOCAL new-routing-mark=to_WAN2 passthrough=yes



Step-6
add dst-address=0.0.0.0/0 gateway=172.17.0.1 distance=1 routing-mark=to_WAN1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=172.18.0.1 distance=1 routing-mark=to_WAN2 check-gateway=ping

Step-7
add dst-address=0.0.0.0/0 gateway=172.17.0.1 distance=1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=172.18.0.1 distance=2 check-gateway=ping

Do both routes in step 6 show as Active in your routing table?

Thanks Sir for your q.
Yes both routes shows active in routing table.

Try adding two more routes - the same as step 6, but opposite GW's and distance = 2... Backup default GW for both policy routing tables. Then disable the ISP1 connection and see if ISP2 becomes active.
