I am trying to setup my FreeBSD 4.10 box as an internet gateway for a =
small
home LAN (2x Win XP and 1x Win 98SE)
The LAN operates without any problems when using the Win 98SE box as a
gateway - all computers can access the internet
I have two nics installed in the FreeBSD box:
dc0 is the LAN interface via 4-port Linksys hub
dc1 is the WAN interface via cable modem
I have successfully connected to the internet with dc1
I can ping all other machines on my home LAN with dc0 and vice versa
I cannot access the internet from any machine except the FreeBSD gateway
ifconfig looks like this:
dc0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::204:5aff:fe76:55f0%dc0 prefixlen 64 scopeid 0x1

sl0: flags=3Dc010<POINTOPOINT,LINK2,MULTICAST> mtu 552

The contents of /etc/rc.conf are:
hostname=3D"sara.mshome.net"
ifconfig_dc0=3D"inet 192.168.1.1 netmask 255.255.255.0" =
ifconfig_dc1=3D"DHCP"
<snip> inetd_enable=3D"YES" gateway_enable=3D"YES"
When I try to ping an outside address from a Windows box, I get this
response:
"Ping request could not find host www.freebsd.org. Please check the name =
and
try again."
When I try to ping a known good URL, I get this response:
Pinging 68.99.63.5 with 32 bytes of data:
Request timed out.
Ping statistics for 68.99.63.5:
Packets: Sent =3D 4, Received =3D 0, Lost =3D 4 (100% loss)
I have tried setting the DNS servers on the Windows box to the addresses
listed in /etc/resolv.conf:
68.105.161.20
68.1.18.25
68.10.16.30
I have also tried setting the DNS address directly to the default =
gateway
192.168.1.1 and get the same response.
While searching around in /stand/sysinstall I found the named daemon
enabled. I disabled with no change (I have since re-enabled it because =
I
believe that was the default setting when I installed FreeBSD)
FWIW, here's output of netstat -rn on the FreeBSD box:

And the results of netstat -rn on the Windows box:

I'm not sure what to do next. For some reason the Windows cannot access =
a
name server. From what I understand from the literature I've been using
(FreeBSD Handbook, Lehey's The Complete FreeBSD, and Anderson's FreeBSD: =
An
Open-Source etc etc) all that should be needed is set =
gateway_enable=3D"YES"
in /etc/rc.conf and I've done that.
Google revealed some info on using natd for PPOE, but not sure if that
applies to this problem.
All suggestions/out-right solutions appreciated.
TIA,
Jim C. =20
