Problem can be in how you are cabled or how you assign private lan
IP address to xp box behind FBSD.

An single xp box cabled to your FBSD needs to be cabled using an
crossover cable. An normal configuration is cabling FBSD box
directly to public internet cable or dsl modem and then have all the
xp systems cabled to hub and the hub cabled to FBSD box.

Xp uses DHCP to automatically get an network ip address assigned and
the reference DNS server ip address to use. On an private lan you
have 2 ways of doing this. The manual way is to enter the network
assigned ip address and dns servers ip address into xp. The other
way is to install an DHCP server software on your FBSD gateway box
so xp can get the info it needs automatically.

Subject: IPF/IPNat router/gateway


   Hello.  I apologize for asking a question which has been asked
several
   dozen times before, but none of the prior-offered solutions seem
to
   work.

   I'm trying to use a freeBSD box (v 5.1) as a gateway/router for
my
   network.  I've got a static IP range for the network, but can't
get
   things running.  (...the local machines are all running Windows
XP
   Pro)

   The local machines can connect to my ISP when they're plugged in
to
   the uplink, whether individually or through a hub, and the
freeBSD box
   can as well.  ...however, a machine plugged into the BSD box is
unable
   to ping the BSD box and vice versa.

   IPF is set to pass in/out quick all from any to any

   IPNat has the following rules set:

   map rl0 192.168.1.0/24 -> x.x.x.254/32 portmap tcp/udp
10000:40000
   map rl0 192.168.1.0/24 -> x.x.x.254/32

   IP of the BSD box is x.x.x.254, mask 255.255.255.224 on the
external
   NIC
   IP of the BSD box is 192.168.1.1, mask 255.255.255.224 on the
internal
   NIC

   the lone machine connected to it at the moment is set on
   IP 192.168.1.2,
   mask 255.255.255.224,
   gateway 192.168.1.1

   ...and rc.conf has gateway_enable, ipfilter_enable and
ipnat_enable
   all set to "YES"

   thanks.
