Perfect, Thanks

This looks good, but doesnt seem to cover the issue if one of the two WAN ports (ISPs) goes down. Every other session will fail.

Yes?

Is there a different routine to add redundancy to this?

Here you have some additional confoguration:

Does two gateway balancing function with Load Balancing Persistent or it is needed just Load Balancing




(Albanian) - Two gateway balancing funksionon me Load Balancing Persistent apo duhet te besh vetem Load Balancing te thjeshte

it depends if you have any persistent route than use that example, if not just continue with load balance only.

(Albanian) versioni me persistent route eshte vetem nese ke te till, nese jo atehere vazhdo me vetem load balance.

This is good.

If ping fails to wlan1, then all traffic marked odd go’s to the wlan2, the oposite is also true.

Any suggestion?

Thanks

What heapands if we have 2ISP to 2wlan LINKs with other MT and other subnets?

I have proved last post Load Balancing but thats dont work for me. becourse: 1.isp=odd 2.isp=even on two links links with wireless wlan1=192.168.2.1/30 wlan2=192.168.3.1/30 whan wlan1 make connection on odd and wlan2 on even this Load balancing is unusual for this situation. or

I got the same situation. i have got two ISP & 2 LAN and Load Balancing operates ok.

Take care of other configurations.

I know what you mean. Thats work if is just 2lan behinde load balancing, but I have 2 LINKs, for ex. after 192.168.2.1/30 in next MT I have 192.168.4.1/24, and also after 192.168.3.1/30 in next MT I have 192.168.5.1/24. So first adresses wich is load balanced is just 2adresses, and for 1day can make just 1 connection, so it is same like I predefine wich Isp on wich LAN. There is no Load balancing. :frowning: I finde on wiki also LOAD BALANCING OVER PORTS, and thats work nicely to me, but still not perfects.
