DHCP and RAS question


Networking, Remote access, DHCP, RAS Server, Mobile, PDA

I have about 20 VPN users who remote into the server. I am having a problem with the DHCP server giving IP addresses to the PDA. The DHCP server is giving them 192.168.11.12, which is the DHCP server itself, and every PDA should have a different IP but they don't.

How do I configure the RAS and or the DHCP server to assign different IP addresses to the PDA's?

Thank you?

Under the DHCP scope there should be a category called Reservations. You can add a reservation by right-clicking on this heading and choose New Reservation. Give the reservation a name which will show up in your AD DNS, assign an IP address within the scope and enter the 12 hex digit MAC address of the PDA device. Then enter any description text desired. You can choose either DHCP, BOOTP, or both. You will probably want to segment the DHCP range so that all the PDA devices are within a range. In other words, put the PDA devices in 192.168.11.200-220. The rest of the range (50 addresses) will then be available as needed for other devices.

I didn't see the subnet mask in your listing.

There are a few details missing from your question and some clarification is needed.

1. What VPN server are you using?
2. What DHCP server are you using?
3. What DHCP scopes have been configured to be given out to clients?
4. What DHCP options are configured for the clients?
5. Do you want to use address reservations for the PDA clients?

I think I put this in the wrong category before:

The VPN and DHCP service are located on the same server, we are using Windows server 2003.
The DHCP scopes that I am using are:

Address Pool- 192.168.11.150- 192.168.11.225
Address Leases
Reservations- I have no reservations
Scope Options-

003 Router- 192.168.11.10
006 DNS Server- 192.168.11.12
044 WINS/NBNS Servers- 192.168.11.12
046 WINS/NBT Node Type- 0×8

Server Options- I have nothing

5. Do you want to use address reservations for the PDA clients?

On this one, I could use address reservations for the PDA clients, but I am unsure how to do this when all I have is 75 IP addresses for my whole network.

I have 20 computer users
3 remote laptop users
20 PDA users
