My ISP provides me up to 5 dynamically assigned addresses out of a /20 block. I have more than 5 machines on my network, so I have no choice but to run NAT, however I would like to force two of those machines onto their own external addresses. If I had static addresses, I could simply alias the addresses into the external interface and then use "binat" in pf to redirect the traffic. However, the addresses have to be requested from the DHCP server, and expire after 4 hours. I can get this to work by running the NAT function under QEMU and just giving the virtual machine several interfaces bridged to the physical external interface. Running a VM is far from ideal. Is there any way I could set up a virtual network interface that could be bridged to the true interface and grab its own DHCP address? Thanks, Raymond Wagner
