pushing data from internal to external and back

Im setting up a basic load balancing setup but was curious what is the standard when building out a configuration.

 

external subnet(VIP)<->F5<->internal subnet(nodes)

 

I just want to get the routing taking care, so when a node sends data, it hits the DFG(10.43.12.1 - which is the F5), then pushs the data out to VLAN 121. Does this make sense?

    Hi,

     

     

    I'm not exactly sure what you're trying to ask. So here is a general description of a few related items.

     

     

    If a host behind LTM responds to load balanced traffic, LTM will send it back out to the same MAC address it was received from using Auto Lasthop (SOL2211: Using auto lasthop and lasthop pools for firewall load balancing - Click here).

     

     

    If a host behind LTM originates traffic, then there must be some type of configuration object to pass the traffic. Ideally, you would use virtual servers as these provide the most configuration options. You could also use a default SNAT or SNAT list.

     

     

    The LTM configuration guide should provide more info on these concepts. If you have more specific questions on your scenario, please let us know.

     

     

    Thanks,
