Basic Http Load Balancing issue when not using Template wizard

Hi Community. I'm using the last F5 BIG-IP LTM VE, i would like to create a simple http load balancing. it's works fine when i create it using the default template in templates and wizard/generic http. When i create my pool / Virtual server manualy, i can telnet the virtual ip/port but the redirection to my pool does not work. I compared the things created by the wizard and mine.. i did not found any difference... I tried to create it using the shell and same issue. Maybe something i miss. please help! Thanks in advance. Quentin.

  • Hi Quentin,

     

     

    Do you have SNAT automap enabled on the template virtual server but not on the manually created one?

     

     

    If that's not the issue, can you reply with the virtual server and pool definitions by running the following commands for both VIPs/pools?

     

     

    b virtual VIP_NAME list

     

    b pool POOL_NAME list

     

     

    Thanks, Aaron

  • You can enable SNAT automap manually under the virtual server properties. Just set SNAT to Automap.

     

     

    You can also check the box for enabling port translation. And you don't need an HTTP class by default.
