I am having a problem getting users who get their dhcp from my
system to be able to connect to the internet.  On one network interface
my server can connect to the internet no problem - that's device vr0.

On another, rl0 - I have a connection to the local network - no problem
connecting to local machines from the server.  The problem is that
the local machines cannot access the internet through the FreeBSD
server. 

Here is the output of ifconfig;

fwe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 02:11:d8:b3:0e:43

And here is the ipv4 part output of netstat -nr

# netstat -nr

192.168.1.255      ff:ff:ff:ff:ff:ff  UHLWb       3      330    rl0

It is machines that connect and receive via DHCP 192.168.1.2 and above that
can't connect to the internet though the server.  I don't know a whole
lot about route - I have been attempting a variation of route commands
without success.

If anyone by looking at my information can suggest a route command, or 
suggest a way to dig for more information on this it would be greatly 
appreciated.


lot about this
