Problem with my DHCP

Hi all,

Ok, I feel kind of silly, I am sure you will laugh but I am new to these kinds of things. I am working on my server and got as far as DHCP, and now I am hung up. My setup: I have two network cards, one will route data from the internet, the other will serve clients. Simple. The routing works great, but DHCP, not so well.

Here is a copy of my dhcp.conf file; the 192.168.254.xxx is the network my FreeBSD will serve. It is supposed to offer 20-150 for the clients. 192.168.255.xxx is the network that is being served. That number will change, for this is a test setup.

dhcpd.conf file:

Code: 
 #options and netmask
 #Place a domain name here if you have one.
 #You can make one up. If you do not have a real domain name do not use a real one 
 #and do not use a real end like .com ,.net ,.org. Use something like "unreal.fakenet"

option domain-name "home.bsd" ; 

 #replace xxx with the IP of the DNS. 
 #If you have more than one use a comma between them
 option domain-name-servers 66.234.112.70, 66.234.112.71;

 #IP of the gateway if you have one comment out this line if you don't have one.
 option routers 192.168.255.254 ;

 #the dynamic DNS update
 ddns-update-style none;

 #lease times in seconds for clients
 default-lease-time 3800;
 max-lease-time 18000;

 # IP subnet netmask and lease range of addresses
 subnet 192.168.254.0 netmask 255.255.255.0 {range 192.168.254.20 192.168.254.150;}

 #The subnet mask for the client
 option subnet-mask 255.255.255.0;

 #end of dhcpd.conf
 
Post the outputs of

$ ifconfig

and

$ netstat -nr

The line with
Code: 
option routers 192.168.255.254 ;
looks wrong to me but I'd have to know what addresses are bound to which interface.
 
the 192.168.254.xxx is the network my FreeBSD will serve. It is supposed to offer 20-150 for the clients. 192.168.255.xxx is the network that is being served.

Those are two different subnets. This is not going to work.

Code: 
#IP of the gateway if you have one comment out this line if you don't have one.
 option routers 192.168.255.254 ;

This gateway is outside the subnet you're giving to your clients.

It works. Yep it was my router, I was pointing to the "internet router" not defineing what the client PC's will see. THanks!

I do notice it is working, but I am getting an netmask error on xl0 and a binding error, is that normal, or is my config too simple?
 
What error? And do you get the error on the server or on the client?
 
Server, with binding to the interface and ignore requests from Xl0 because of netmask. I don't have the exact error, but maybe it was more of an informative thing.
