Re: IP Helper-address questions [7:247]
Actually, you'll want to make the pools only as big as the subnet, unless you know some trick I don't Muhammed. Each pool will need a default gateway assigned as part of the scope, and unless you're doing a /16 range for 192.168/16, then you'll want a pool for each 192.168/24 network. Don't forget to take advantage of the global attributes. Set your DNS, WINS, and whatever settings are the same for each pool as a global setting, and only those settings that need to be unique for each pool (Gateway is all I can think of). This way you don't have to specify these same settings for each pool. A pool-specific attribute will also override the Global attribute for that pool, so even if you had a local WINS and/or DNS server that you want one network to use, still set the Global for whatever is the main configuration. Don't forget if you use WINS to set the node type to 0x8 (hybrid). -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ ""Muhammed Khalilullah"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Yes, The DHCP server will check the IP address of the > interface on which you have configured the IP Helper > address command.

Re: IP Helper-address questions [7:247]
Yes, The DHCP server will check the IP address of the interface on which you have configured the IP Helper address command. So make pools on the DHCP server accordingly. eg: Router's interface 192.168.1.1/16 Server' pool 192.168.0.1-192.168.255.254 wil work. Muhammad Khalilullah CCNP, MCSE --- "Jason J.

The source MAC address is the router's address (assuming the packet only went one hop), but the source IP address is 0.0.0.0, so that doesn't help. What does help is that the DHCP packet has a GIAddr (Gateway IP Address) field. The router that forwards the packet puts its own address in that field. The router puts the address for the interface that the DHCP Discover packet came in on. The remote DHCP server can figure out which scope it's dealing with from that info. The GIAddr should be from the same subnet as the requesting host. Priscilla >""Jason J.

Re: IP Helper-address questions [7:247]
Yup, you got it. Just set up the extra scope(s) for the subnet(s) you have the ip helper-address enabled port(s) on. The DHCP server sees the source address (or perhaps network address/mask, I'm not sure the down and dirty details), and sends an appropriate DHCP address from the scope that fits that subnet. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ ""Michael Snyder"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I happen to be a ccnp and mcse.

I happen to be a ccnp and mcse. I get how ip helper-address works. Also work with microsoft dhcp servers. How do you setup a scope for a remote subnet, and how does the dhcp server know how to hand out the correct ip leases for a non-connected subnet? Does the dhcp server look at the source address of the interface of the forwarded helper-address packets? Then match up the correct scope with the router interface ip address? ""Jason J.

Re: IP Helper-address questions [7:247]
Actually, the IP helper command is placed on the interface that is recieving the broadcasts. Now you have to decide which router is supposed to recieve the broadcasts. But in usual case, Clients usually try to communcate with the PDC for authentication and other stuffs. So, i think it would work to configure ip helper-address w.x.y.z on the ethernet interface of router 1 only (where w.x.y.z is the ip address of your PDC, but if you have multiple PDCs then you have to give the directed-broadcast address and also have to use ip directed-broadcast command).

RE: IP Helper-address questions [7:247]
I assume when you say PDC, you are referring to an NT server PDC. I must also assume you have TCP/IP installed on all NT servers needing to communicate to each other. If so, then the ip-helper command is of no use. It merely forwards bootp and DHCP requests. If you need a PDC and a BDC to communicate then just make sure both servers are reporting to a common WINS server. From the WINS server the PDC and BDC will know what IP addresses they nees to use to communicate. As long as the servers can ping each other and WINS is configured properly then you are cooking.
