Hello, my name is Robert. I am trying to configure my FreeBSD 4.0 =
as a gateway. I have a 3 computer network. My ISP is cox@home. (Cable =
Modem)
Computer 1 name is FOO (will serve as gateway)
Computer 2 name is BAR (Running Free BSD 4.0)=20
Computer 3 name is BAZ(Running Dual Boot Win2000 Professional & Red =
Hat Linux 7.0)
I compiled IPFIREWALl, IPDIVERT, IPFIREWALL_VERBOSE, and =
IPFIREWALL_DEFAULT_TO_ACCEPT in my Kernel on computer FOO.=20
=20
I put the following lines in my rc.conf file on computer FOO
hostname=3D"CX628451-A"
ifconfig_dc0"inet 192.168.1.1 netmask 255.255.255.0" # Private IP
ifconfig_dc1"inet 24.21.112.xxx netmask 255.255.255.0" # Public =
IP
gateway_enable=3D"YES"
defaultrouter=3D"24.21.112.1" # Gateway for my ISP.=20
natd_enable=3D"YES"
natd_interface=3D"dc1"
natd_flags"-l -u -s -m"
firewall_enable=3D"YES"
firewall_type=3D"OPEN"=20
The rc.conf fie on BAR looks as follows.
hostname=3D"BAR"
ifconfig_x10=3D"inet 192.168.1.2 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 computer BAR. I am =
able to ping both private and public addresses. I am also able to ping =
FOO defaultrouter IP and DNS IP that I have set in resolv.conf. But I am =
unable to ping an address out on the internet on computer BAR. Of course =
I am able to ping address on the internet with computer FOO. I can =
telnet into Foo via BAR and vice versa. I also verified that the line =
natd 8668/divert was present in /etc/services. =20
Any help on this matter would be greatly apreciated.=20
Thank You,
Robert Daniels =20
