Hello
I want to use load balancing with fault tolerance.
Here is my configuration on the picture.

All device have there own public ip address, also all clients are using public ip addresses, i am not using masqureiding or nat, i have enabled on gateway interface proxy arp and thats all.

I want to use load balancing and fault tolerance with
93.188.x.20 <--> 93.188.x.21
93.188.x.22 <--> 93.188.x.23
Is it Possible?
Thank you

You need a "pcc configuration" on RB600. I am not capable of giving
you instruction on pcc, because never tested it my self, but you
can find it on the wiki:
