  • Assign the external NIC of the FreeBSD router all 20 addresses. First address as normal, the other 19 as alias.
  • Use a RFC 1918 address from 10/8 or 192.168/16 for the internal NIC and your LAN.
  • On the same FBSD router configure a packet filter like pf which has Network Address Translation capabilities.

    Outgoing connections, initiated by your LAN clients, will now use one of the 20 external IP addresses,
