profiles PR-fastL4_30minutos {}

 

}

 

 

 

 

 

 

profile fastL4 PR-fastL4_30minutos {

After with other load balancer ( ALTEON ) I didn't have problems, but now with f5 I have some problems.

  • Hi Miguel,

     

     

    If you have tcpdumps showing the issue, I'd suggest opening a case with F5 Support to get help investigating the possible cause(s).

  • Hi, I have captures where you can see lost UDP in BIG-IP F5.

    I've opened new case with F5 support, i will write the respond of support.

     

     

     

    Thanks.
