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)
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.
I put the following lines in my rc.conf file on computer FOO
hostname="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="YES"
defaultrouter="24.21.112.1" # Gateway for my ISP.
natd_enable="YES"
natd_interface="dc1"
natd_flags"-l -u -s -m"
firewall_enable="YES"
firewall_type="OPEN"
The rc.conf fie on BAR looks as follows.
hostname="BAR"
ifconfig_x10="inet 192.168.1.2 netmask 255.255.255.0" # Private non-routable IP
defaultrouter="192.168.1.1"
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.
Any help on this matter would be greatly apreciated.
Thank You,
Robert Daniels
