One Server, two interfaces

[Alan Neville]

Jeff:
Apologies for the delay in getting back to you, but I have attempted  
adding another scope as suggested to my /usr/local/etc/dhcpd.conf,  
but to no avail. The following is a copy of my configuration file;

#option domain-name "example.com";
option domain-name-servers 213.94.190.194, 213.94.190.236;
option subnet-mask 255.255.255.0;

default-lease-time 3600;
max-lease-time 86400;
ddns-update-style none;

# rl0 (unhealthy)
subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.10 192.168.1.200;
  option routers 192.168.1.1;
}

# dc0 (healthy)
subnet 192.168.100.0 netmask 255.255.255.0 {
   range 192.168.100.10 192.168.100.200;
   option routers 192.168.100.1;
}

When I plug a system into the "healthy" side, i get a .100 address.  
This is working fine. However, I never get a .1 address when plugged  
into the "unhealthy" side. I have added teh scope and restarted teh  
dhcpd service by issuing /usr/local/etc/rc.d/isc-dhcpd restart. The  
following is a copy of the output;

# /usr/local/etc/rc.d/isc-dhcpd restart

Wrote 2 leases to leases file.
Listening on BPF/dc0/00:04:e2:5c:91:dc/192.168.100/24
Sending on   BPF/dc0/00:04:e2:5c:91:dc/192.168.100/24
Sending on   Socket/fallback/fallback-net.

I don't see any problems? Any suggestions?

Many Thanks,

A
