    It's recommended to use destination address affinity to load balance traffic across multiple ISPs. You can use the default profile or create a new one with a customized values , and assign that profile under the resource tab of your virtual server configuration.

    Hi kolom, thanks for answer me, but because I am using a VS forwarding ip I cant use a persistence profile, I tried using a VS performance layer 4 but it doesn't work

    In case of using Performance L4 VS , by not working , you mean the persistence part or the traffic part .

    The traffic part doesn't work without pool assign. and when I assign a default pool the F5 just pass the traffic to the DG and not as a next hop. Causing that all the traffic goes to the ISP routers and showing their routers web login promt

    Use Performance L4 , and uncheck "Address Translation" and "Port Translation" under VS's advanced configuration . Based on your network environment , you can configure the BIGIP to allow asymmetric traffic by configuring the fastL4 profile with the loose initiation and loose close options.
