    Hi minheo​ 

    It is not possible or supported to configure different default gateways per device in an F5 HA pair (BIG-IP tenants on rSeries/F5OS). The default gateway must be the same on both units, and any change will be synchronized across the HA pair. The supported method for gateway redundancy is to use a floating IP (VRRP/HSRP) on the upstream L3 device.
