Use F5 as a router

Hello all,

 

I would need to make my F5 to route traffic. Is there any way to achieve this? I have tried to use as default gateway the F5 floating IP and also using a Forwarding (IP) Virtual Server but without luck.

 

I don't know if I'm configuring right the Virtual Server, I'm using as source and destination 0.0.0.0/0 and I've applied a fast L4 profile with Loose initiation enabled and Reset on timeout disabled.

 

Am I doing something wrong? Can this be done other way?

 

Thanks!

    The simplest configuration would look something like this:

     

    • Define a system default route (0.0.0.0/0, gateway IP)
    • Wildcard forwarding VIP
      • Protocol: whatever you need here
      • Source: 0.0.0.0/0
      • Destination: 0.0.0.0/0
      • Port: 0
      • VLAN and tunnel traffic: client-facing VLAN
      • Source address translation: disabled
      • Address/port translation: disabled

    This VIP has the effect of listening to all traffic, maintaining true source and destination in the packet, and forwarding to the system route. Traffic routes to the BIG-IP via the client-facing VLAN self-IP.
