What I do nowadays to solve this kind of problem is to use gif(4) tunnels to create point-to-point links between all machines that need to have 'public' addresses and the firewall/router. All the ethernets can then have 10.* addresses, with the scarce 'real' addresses only allocated to the gif interfaces on the machines that need them. There's obviously a slight performance penalty, but typically not noticeable in the normal case where your internal (10 or 100Mbit) ethernets are faster than the connection to the ISP.
