How to create wide IP for generic host?

Hi guys, I'm trying to create a wide ip for a generic host directly without the GTM talking to any LTM.



I know that in order to do this I need to configuring the following:


data center -> server -> pool -> wide IP




However, while I was configuring the server settings, there is a section under "Resource" that requires me to configure the virtual server setting (optional setting). My understanding for this is if I'm configuring for Generic host, I do not need to configure the virtual server settings (pls correct me if I'm wrong)...




Now, the problem is... if I do not configure the virtual server setting, I will not be able to see the server during the Pool configuration.




I tried searching around the forum and config guide but I'm not able to find any topic that talks about this...




Am I missing any steps, how do configure wide ip for generic host without configuring the virtual server settings?

  • Hi Darren,


    I ran into very scenario during internal training sessions about the GTM. The one thing you have to remember is that you have to change your mindset from the F5 perspective of how it views the order of configuration.



    Here is the following order of creation in generalization.



    Data Center --> Servers --> Virtual Servers --> pool --> Topology (optional) ---> WideIP



    That being said you must remember that Generic host is really a device that has many virtual services. When seen in this fashion all general hosts need a virtual server even if the IP address is the same. For example you can have a general host but then you need a virtual service which is port 80. So the rule of thumb is to always understand that General Host requires a virtual service.



    I hope this helps






  • Hi All,



    do you know if we can offload a SSL certificate on a GTM? I am trying to add three VPN devices behind a wide ip config on the GTM and we only have 1 ssl certificate. Any help would be much appreciated.

    Mm... GTM is a DNS server. Unless you're running DNSSEC there's no certs involved...



    If you only have 1 cert, simply copy the cert and key from one device providing the service to the others. You'll need to check your license agreement with your CA provider whether that's legal or not though.
