Constraints for using IP address and port lists

When you use IP address lists and port lists to configure the source or destination address in a virtual server, make sure you keep these constraints in mind to ensure successful configuration:
  • You cannot remove an address list from the BIG-IP system if the list contains a virtual address in use by another virtual server.
  • No two virtual servers can contain the same IP address in their respective address lists.
  • The address ranges specified on a virtual server cannot overlap. For example, two or more ranges specified on a virtual server cannot contain the IP address
    10.20.10.5
    .
  • All addresses in an address list must be of the same type (either IPv4 or IPv6).
  • In a range of addresses or ports, the beginning value of the range must be lower than the ending value. For example, you cannot specify a range of
    10.10.20.30
    -
    10.10.20.10
    .
  • All addresses in an address list must belong to the same route domain.
  • Another virtual server cannot specify an overlapping end point as defined by: the same source or destination address and mask, the same service port, the same route domain ID, and enabled on the same VLAN.
