Hi - i am trying to configure a Sync only device group  F5 deployment in GCP - i have 2 single NIC f5s .

to setup device trust i need to have a NON Management ip address . can you help me understand how you set it up on your environment.

did you add a second ip to interval vlan on both devices and allowed communication on heartbeat ports between the 2 devices on that port ?

secondly how did you configure virtual servers - was it the same ip address on both devices ?

thanks

    Hi awan_m 

    Yes, add a second network interface for the non-management traffic. Regarding the IP address, usually I have a different IP address on each device.

    Please shoot me a message over this website if you want more help and we can email directly, thanks!!
