RRAS DHCP

I have a reservation in my DHCP server for a laptop.  The user is connecting the laptop remotely through RRAS and he is not getting the assigned "Reservation".

Is it possible to assign an reserved address via dhcp through RRAS vpn connection?

If so, what am I doing wrong?

When I check RRAS, I find that the the radio button for "This server can assign ipv4 by using Dynamic Host Configuration Protocol" is selected.

Have you also configured DHCP Relay Agent in RRAS to point to your DHCP server?

DHCP Relay Agent is configured to IP or "Internal" ?

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

Only ways to assign reservations with RRAS is by the following:

1. Use Active Directory Users and Computers.  Go to the Dial-in tab on the users properties and Assign Static IP Address

2. On the VPN client, assign it a static IP when connecting.

OK, and one more question :) You have probably IP address reservation using MAC of LAN card of that computer, right? But remember, when you create VPN connection then virtual NIC connection is established :) You should try ith IP reservation of that virtual connection.

For test, use VPN connection and then (when you are connected over VPN) run in command-line

ipconfig /all

and locate that vitrual connection's MAC address. Create IP reservation for it (I'm not sure if it would work because it can create random MAC address). But you can check it :)

Thanks iSiek,  I will try this tomorrow.   I can't reach this gentleman until the morning.  Sounds like a good idea.  I know exactly what you are talking about.
