F5 Change DNS config

Hi,

 

I'm new here, and I don't know how f5 work at all...

 

We have a tunnel IP with a customer, with his DNS. but his DNS is closed, and I need to add a new DNS to the configuration. It's on CentOS I can't edit the /etc/resolv.conf because it's overwritten. I saw a restorecon in network-scripts/network-functions on resolv.conf. In the context it points on "system_u:object_r:net_conf_t:s0"

 

I don't know anything on SELINUX but it's disabled and only enabled at first view by f5...

 

Anyone know anything or where can i search?

 

Thank you in advance Bye

    Hi,

     

    In order to change DNS using F5 you have to do it using cli (tmsh) or GUI.

     

    Using GUI,

     

    • connect to gui

    • System ›› Configuration ›› Device ›› DNS

       

    • And modify your dns

    Keep me in touch.
