Hello, my name = is=20 Robert. I am trying to configure my FreeBSD 4.0 as a gateway. I = have a 3=20 computer network. My ISP is cox@home. (Cable Modem)

Computer 1 name is = FOO (will=20 serve as gateway)

Computer 2 name is = BAR (Running=20 Free BSD 4.0)

Computer 3 name is = BAZ(Running=20 Dual Boot Win2000 Professional & Red Hat Linux 7.0)

I compiled = IPFIREWALl, IPDIVERT,=20 IPFIREWALL_VERBOSE, and IPFIREWALL_DEFAULT_TO_ACCEPT in my Kernel on = computer=20 FOO.

I put the following = lines in my=20 rc.conf file on computer FOO

=20 hostname=3D"CX628451-A"

ifconfig_dc0"inet = 192.168.1.1=20 netmask 255.255.255.0" # Private IP

= ifconfig_dc1"inet =20 24.21.112.xxx netmask 255.255.255.0" # Public = IP

=20 gateway_enable=3D"YES"

= defaultrouter=3D"24.21.112.1" #=20 Gateway for my ISP.

= natd_enable=3D"YES"

=20 natd_interface=3D"dc1"

natd_flags"-l -u -s=20 -m"

=20 firewall_enable=3D"YES"

= firewall_type=3D"OPEN"=20

The rc.conf fie on BAR looks as=20 follows.

hostname=3D"BAR"

ifconfig_x10=3D"inet = 192.168.1.2=20 netmask 255.255.255.0" # Private non-routable IP

= defaultrouter=3D"192.168.1.1"=20

= gateway_enable"NO"

With this setup I am able to ping = computer FOO from=20 computer BAR. I am able to ping both private and public addresses. I am = also=20 able to ping FOO defaultrouter IP and DNS IP that I have set in=20 resolv.conf. But I am unable to ping an address out on the internet = on=20 computer BAR. Of course I am able to ping address on the internet with = computer=20 FOO. I can telnet into Foo via BAR and vice versa. I=20 also verified that the line natd 8668/divert was present = in=20 /etc/services.

Any help on this matter would be = greatly=20 apreciated.

Thank You,

Robert Daniels =
