I have been trying to get NAT and IPFW running on my home machine FreeBSD4.3 Release to turn it into a Broadband firewall. I have one ISA Realtek 10MB card and 1 Realtek 10/100 PCI NIC and a 3com Cable modem. I have compiled the IPFIREWALL_VERBOSE and IPDIVERT options into the kernel and added: gateway_enable="YES" firewall_enable="YES" firewall_type="OPEN" natd_enable="YES" natd_interface="ed1" to my rc.conf. My internal net is using the 192.168.1 network address. My exterenal nic is using DHCP. Internal IP is 192.168.1.5. Here's the problem. Once the machine is up I can ping names and numbers from the Gateway machine to the outside world and I can ping to the inside network from the gateway. I can ping both interfaces from my machine on the network but I cannot ping internet addresses from inside the network. It seems like the NAT is not working properly. I am able to access my gateway machine from the outside world through SSH. Below is a copy of my rc.conf: gateway_enable="YES" hostname="hornet" network_interfaces="rl0 ed1" ifconfig_rl0="inet 192.168.1.5 netmask 255.255.255.0" ifconfig_ed1="DHCP" inetd_enable="YES" linux_enable="YES" sendmail_enable="NO" sshd_enable="YES" log_in_vain="YES" ipfilter_enable="YES" ipfilter_flags="" ipmon_enable="YES" ipmon_flags="-Dsvn" ntpdate_enable="YES" ntpdate_flags="ogden.bendnet.com" firewall_enable="YES" firewall_type="OPEN" natd_enable="YES" natd_interface="ed1" natd_flags="-redirect_port tcp 192.168.1.5:22 22" Any ideas or suggestion are appreciated.
