@dipan29 That is for resetting all connections whenever the DHCP client changes its IP. If your other uplink is a static IP, you only need one DHCP client.
@marfillaster thanks for the response,
Also, I tried doing the same and gracefully it works for the local network right out of the box. As in for all interface lists LAN. However, My requirement was a little different and could not manage to get it working post Router OS 7.
I would require something similar but for the following scenario
- Having one DHCP Client and one with Static IP or PPPoE Client (here the gateway caused an issue when I tried to replicate cause for ether1 when its PPPoE the gateway IP isn't defined)
- Ensuring that both the WAN IPs can be used for DST-NAT - for any local subnet
- I would be having generally two subnets - one for home lab and one for normal home users. For the home lab I won't really want to do load balancing but just ensure that the DST-NAT for that network works from both the WANs.
- For normal home users, I would be okay if it goes out through ether1 (PPPoE/Static) most of the times but have an address-list called DUAL say that can only get Load Balancing when tagged to it. In other words, only the addresses tagged as DUAL can have the load balancing.
I tried finding a lot of guides on the internet but could not have something from reddit or mikrotik forum that serves my purpose (some claim to, but they just don't get connected).
Also, I am new to this mikrotik, would be glad if you can guide me with some exact details or something from the internet that works.
I'm using this config but, when the ISP 1 has no internet, it uses the ISP 2, however, when the ISP 1's internet get's back, the recursive will still mark ISP 1 as no internet. It only uses ISP 2's internet the whole time, unless I'll restart the mikrotik.

I can help you with all your requests
Has the variable $leaseBound change to $bound now?
Hi @nhan6310 how can we connect to get this configuration set?
I tested this on a MikroTik RB4011, and it worked perfectly. However, I'm encountering an issue that perhaps you could assist with: the load balancing is happening constantly (meaning a PC is continuously switching between the two WANs). Is there a way to configure WAN balancing based on the client's IP?
@quinont the easiest way to to change this is to change the pre routing mangle rule to included a src address list and then you can specify which IP get load balanced or not
Below is how mines looks
add action=mark-connection chain=prerouting
connection-mark=no-mark dst-address-type=
!local in-interface-list=LAN
new-connection-mark=ISP1_conn passthrough=yes
per-connection-classifier=
both-addresses-and-ports:2/0 src-address-list=
MultiWAN-Clients
add action=mark-connection chain=prerouting
connection-mark=no-mark dst-address-type=
!local in-interface-list=LAN
new-connection-mark=ISP2_conn passthrough=yes
per-connection-classifier=
both-addresses-and-ports:2/1 src-address-list=
MultiWAN-Clients
any one can give me recursive fail over gate way
im using NTH
my ip : gateway
my dns :8.8.8.8,8.8.4.4,1.1.1.1
wan1 192.168.1.1
wan2 192.168.254.254
wan3 192.168.0.1
Jovem, que configuração excelente. Testamos em laboratório de bancada, fizemos testes de estresse, usamos conexões diferentes (pppoe, client, etc), e tudo funcionou perfeitamente. Meus parabéns e muito obrigado pelo compartilhamento.
# WAN to LAN
add action=mark-connection chain=prerouting connection-mark=no-mark connection-state=established,related in-interface=ether1 new-connection-mark=ISP1_conn \
passthrough=yes
add action=mark-connection chain=prerouting connection-mark=no-mark connection-state=established,related in-interface=ether2 new-connection-mark=ISP2_conn \
passthrough=yes
These rules are not only from WAN to LAN connections, they also catch connections directed to the router itself (if you remove the connection-state=stablished,related), thats the reason why this two rules also exist:
add action=mark-routing chain=output connection-mark=ISP1_conn dst-address-list=!local new-routing-mark=to_ISP1 passthrough=yes
add action=mark-routing chain=output connection-mark=ISP2_conn dst-address-list=!local new-routing-mark=to_ISP2 passthrough=yes
The output rules are using already marked connections that were directed to the router itself, and now they serve the purpose to route the connections to output from the same interface that they did enter. This have nothing to do with the ECMP routes, the ECMP routes are used only for new originated connections from the router itself to the internet, so you can ping 8.8.8.8 from the router and it will choose one of the two routes, then ping 8.8.4.4 and it may choose the another.
Sorry for my english.
how to deal with bgp routes? Their routing mark beeing overriden
Can anyone please explain what this area is doing?
I have one Static WAN where I need to setup but how do I add the script?
