F5 Load Balance To External Transparent Proxy

Hello,

 

I'm trying to use f5 ltm as a load balancer over 2 external transparent proxies.

 

the f5 will be the default gateway for the users and should load balance several udp & tcp ports to an external transparent proxies.

 

it should also reflect the client ip.

 

my questions are:

 

  1. which virtual server type will be appropriate for this deployment?

     

  2. is using virtual group a must here in order for the f5 to act as a transparent as well?

     

thanks

 

  • It depends on what you want.

     

    If all you want is load balancing, a performance L4 Virtual will do just fine, and a single virtual can support both TCP and UDP.

     

    Your external proxies can then be configured as pool members and you can select the load balancing algorithm of choice.

     

    If you want to be able to use irules to do other things at layers 4 to 7, then you will need to use standard VIPs. With Standard VIPs, you can only have them as either TCP or UDP (not one virtual handling both). Standard VIPs give you the ability to apply TCP optimizations etc and do do pretty much anything to the traffic via irules and or Local Traffic Policies.
