First make sure you're using a supported NIC in the FBSD box, or a "fully compatible" NE2000 clone (your mileage may vary). Next, test basic connectivity with "ping" (both FBSD->Mac & vice versa). >What netmask should I use. I'm not connecting externally, what IP's should I use? Per RFC 1918, the following ranges are reserved for private (non Inet-connected) nets: 10.0.0.0 - 10.255.255.255 (class A net, up to 16 million hosts) 172.16.0.0 - 172.31.255.255 (class B; up to 64k hosts on 16 networks) 192.168.0.0 - 192.168.255.255 (class C, 253 hosts on 256 nets) Netmask depends on the address class and whether you're subnetting. It specifies the bits that comprise the network number (remaining bits are the host id) by performing a bitwise "AND" between an IP address and the netmask. For example: host = 192.168.0.1 netmask = 255.255.255.0 Here all of the first 3 octets (192.168.0) are used for the network number, and the last byte (1) identifies the host. Using the same netmask, 192.168.1.1 would identify a host on a different network. MjB
