OK, let's start with the simplest possibility:  Are you sure you enabled the
FreeBSD kernel's IP forwarding facility?  In "late model" FreeBSDs you can do
that by simply setting one line in /etc/rc.conf:

gateway_enable="YES"            # Set to YES if this host will be a gateway.

See sysctl(8) for more info.

You shouldn't need to bother with routed or gated just to get a simple setup
working - static routing should be fine.  If the above doesn't work, then
check your kernel's idea of the routing table with a "netstat -rn".

Oh, and the IP address of the FreeBSD machines NIC must be the default
gateway for all the internal machines.  But I suppose that's already been set
if their traceroute gets as far as your gateway box.
