Reconfig of dhcp.conf

Using dhcpd on SLES10 SP3/OES2 SP2.
We have finally gotten a real firewall/router. We are replacing a netscreen
firewall/router with a juniper firewall router with a optional/dmz port. The
old one had a secondary ip configured. With the install of the real
firewall/router, I am sure we will need to reconfig the dhcp on the server.
Follows the existing dhcp conf:
option domain-name "";
option domain-name-servers;
option ntp-servers;
ddns-update-style interim;
default-lease-time 14400;
max-lease-time 172800;
Class "123 DHCP Clients" {
         match hardware;
       subclass "123 DHCP Clients" 1:00:23:DF:86:6D:44;
      # HP a6313w builtin NIC subclass "123 DHCP Clients"
       subclass "123 DHCP Clients" 1:00:06:29:89:D6:CA;

Shared-network EH {
       subnet netmask {
         option routers;
         pool {
           allow members of "123 DHCP Clients";
       subnet netmask {
         option routers;
         pool {
           deny members of "123 DHCP Clients";

The old firewall had relay-agent enabled; will the new firewall need this
enabled also? The dhcp server is on the 192.168.124 subnet (if that
matters). I just want to hand out ip¹s for both networks, nothing fancy. I
would appreciate any ones help in reconfig¹ing the dhcp.
