    Hi all,

    I would like to use DNS load balancing with ispconfig 3. As I read in a mydns manual this should work by changing the priority value (aux) of a DNS A record. The ispconfig interface does currently not allow to change the priority of an A record. It is only possible to change the priority of a MX record.

    Shall I change the priority directly in the mysql table? Or is there another way to change the priority through ispconfig?

    That might be a feature request as well?!

    Thanks for your input.

    You can change this in the mysql db. But as far as I know it is not nescessary to set this value for load balancing at all. Just add more then one dns A-Record for every load balancing target.

    mydns algorithm

    As I know, mydns uses round robin to select the primary IP if all records have the priority 0. That means each record has the same weight.
    If you change the priority to higher values, the corresponding record will have a lower weight and will be returned less.

    I will temporary change the values manually and add a CR.

    Thanks
