I have one interface that the address range is divided between 2 user groups, each needing different egress rules.
The manual talks about being able to set up rules by range of addresses, but the GUI only seems to support CIDR-style address ranges. In theory, I MIGHT be able to use this as the address space is effectively divided in half, but then there are systems on what would be the broadcast address of one CIDR range and the network address of the other, so it does not seem that a CIDR-style address range is what I should use.
How DO I set up an address range to use in the src part of a policy?
