I have an odd(?) NatD setup I am tryin to implement but haven't been able get it working or find adequate resources to help me figure it out. I have a cable modem, and with it I am assigned 4 IPs. Now, as they are not IPs I can subnet, and because I want some basic firewall functions (Blocking NetBios, for instance.), I want to connect the cable modem to my FreeBSD server, then connect a second NIC to a hub on which rests 2 other machines. This part i have wokring ok. What I want, though, is for those two machines to be accessible from the outside world as public IPs through transparent translation on the FreeBSD box. So what I have is: The Internet | | /-------------\ | Cable Modem | \-------------/ | | \--------------------------------------\ | | /---------------\ | 208.166.54.56 | | 208.166.54.57 | | 208.166.54.58 | | | | 10.166.54.56 | \---------------/ | /-----\ /-------------------------| Hub | | \-----/ /--------------\ | | 10.166.54.57 | | \--------------/ | /--------------\ | 10.166.54.58 | \--------------/ Where do I begin in writing the NatD rules that will allow packets destined for 208.166.54.57 hit 10.166.54.57, and for machines on the internet to see 10.166.54.57 as 208.166.54.57 when sending packets back?
