Moving from Fail Over to Using both WANS ??

RouterOS Beginner Basics
2

Sorry, async WAN-s and without Mangle… no idea :slight_smile:


I always do

  1. recursive routing…

  2. MANGLE
    I really recommended to learn and do this one HowTo who have got the best way to use many WAN’s at ones.
    Next you can use any method netwatch/script/pcc etc to just flow the outgoing - then this is small stuff.
    Bandwidth-based load-balancing with failover. This presentation also covers Mangle.
    This was presented at the MUM (MikroTik User Meeting) in New Orelans, USA.

  3. My own detectors of offline and do action with fix that stuff

  4. ISP who is now DOWN should have a remove all connections from conntrack table, and that connection and theyr keepalive will start NEW connection via UP ISP without breake at network.

One of main action here is that:

ip route enable  [find dst-address="0.0.0.0/0" gateway=8.8.4.4 routing-mark="wan2_SM" ]
delay 1s
foreach IPList in=[/ip firewall address-list find list="LANs_via_SM"] do={
 local CurIP [ip firewall address-list get $IPList address ]
 local IP3oct [pick $CurIP  0 [find $CurIP "." ([find $CurIP "." ([find $CurIP "."]+1)]+1)]]
 ip firewall connection remove [find connection-mark~"wan1_Orange<->LANs" src-address~$IP3oct ]
 ip firewall connection remove [find connection-mark~"wan1_Orange<->LANs" reply-src-address~$IP3oct ]
}

With all that points I receive good and FULL working MultiWan.

The last one point is very importand in your situation because he help’s hop to next ISP that users who are using “re-connected” wan.
Other words it’s fix for massive TIMEOUT problem when WAS is offline.

btw, IP Octet manipulation thread.
