Flowtable in a load balancer

Flowtable in a load balancer

[Eliezer Croitor]

I am trying to understand where can I use flowtable on a load  balancer.
Also if and how it will work with PBR.

I have created a nftables load balancer lab at:
.	https://github.com/elico/mwan-nft-lb-example
.	https://github.com/elico/mwan-nft-lb-example/blob/main/run-lab.sh

I know that flow tables cannot work with PBR but not sure on what degree.
Also maybe something is needed possible..

I will try to describe the lab:
1 client 
  ether0: 192.168.125.100/24 gw 192.168.125.254
1 Lan GW 
  ether0: 192.168.125.254/24
  ether5-15: 192.168.205-215.254/24 (10 ~ wan interfaces with ip addresses)
15 WAN Routers
  ether0:  192.168.101.5-15/24( a single ip per WAN Router) (SNAT ie
MASQUERADE)
  ether1:  192.168.205-215.254/24( a single ip per WAN Router)

1 Edge_R_Web_service
   ether0:  192.168.89.99/24 (SNAT ie MASQUERADE) GW 192.168.89.254
(MASQUEARDE to the Real WORLD)
  ether1: 192.168.101.254/24


This lab tests the LB of the LAN GW towards the WAN Routers and verifies the
result via a HTTP request.
The client sends a http request towards 192.168.101.254 and then receives
the ip address of the WAN Router at the 192.168.101.0/24 net.

If it's possible to use flowtable on any of the Routers on this network I
would like to make sure I understood right.

Thanks,
Eliezer
