Configuration should be like below: F5 (10.X.X.X) --- > Firewall (172.x.x.) ---> NAT should be on firewall for 172.x.x.x to 200.x.x.x

 

You need to configure as mentioned below:

 

  1. Configure F5 VIP and pool member should be 172.x.x.x. For example pool member is 172.1.1.1
  2. You should create NAT on Firewall for 172.1.1.1 and it should map to public IP 200.1.1.1
  3. F5 should have routes towards firewall
  4. Firewall should have route towards internet.

I hope this helps.
