Regarding Forwarding IP VS

Hi Team,

 

We are trying to route traffic via F5 LTM i.e. when traffic coming from external network (firewall) we are diverting the traffic to LTM becoz we don't have specified network directly connected to firewall and then we are trying to reach the server. We have created 2 vlan, one for traffic coming from firewall and other vlan in server vlan. Also we created Forwarding IP VS for the server we are trying to connect but still we are seeing the server intermittently in accessible. Is there any step I am missing or other way to make LTM as virtual router.

 

Thanks.

    Hi!

     

    We have recently done this successfully. I advise you to read the following SOL: https://support.f5.com/kb/en-us/solutions/public/7000/500/sol7595.html

     

    Pay special attention to the section: Emulating stateless IP routing with BIG-IP LTM forwarding virtual servers

     

    Also when using a FastL4 profile you need to disable "Hardware SYN Cookie" protection. (Note: Hardware SYN cookie protection may not function as expected on a wildcard virtual server, because hardware SYN cookie protection requires a destination IP/port pair to function properly.)

     

    Ps: Before we made the necessary changes we also had some intermittent issues, but not anymore
