Here's an idea - untested.
set up a network on the single nic - say 192.168.55.xx/24
set up the dhcp to offer leases from a subset of this network - say
192.168.55.128/28
set up fixed leases based upon mac address from the remainder of the
network - i.e. outside the subset above - e.g. 192.168.55.1/28
then route / firewall as required - i.e. trusted known mac address
hence IP address allowed vs unknown guest given an IP address we can
block or otherwise handle.
As indicated, this is not tested but if memory serves, dhcpd will
allow this kind of allocation.
the untrusted wireless users will be able to access other LAN machines
without going through the firewall.
surely that depends upon the subnet they operate on (i.e the subnet mask
in old vernacular) - the two I show above are mutually exclusive but can
both talk to the server.
