I have a question about building a FreeBSD gateway.
I want to create a subnet in our internal company network. I have installed FreeBSD 8.0 RELEASE i386, no updates, right from the FreeBSD CD. Now I want to configure this box as the gateway of the subnet. I have two NICs configured. One external for the company network and one for the new subnet. On this box I can reach any other computer in our internal network, I have internet access, too, and I can reach the box on the subnet. The box on the subnet is able to ping both NICs on my FreeBSD box, but cannot reach any other computer of my company network or the internet. Because I don't need any firewall on this subnet, I thought gateway_enable="YES" in /etc/rc.conf should be sufficient. But it doesn't work. Do I need something else?
# cat /etc/rc.conf
ifconfig_re0="inet 192.168.50.1 netmask 255.255.255.0"
# sysctl net.inet.ip.forwarding
# netstat -rn
