Vpn's, Dns and DHCP

[snipesnab]

Firstly I will explain my current setup and goal:

I have Check POint firewall FP3 installed at my Head Office which is running a windows 2000 network.

I have client PC's running checkpoint secureclient as several remote sites.

When a VPN is negotiated from these remote PC's they are issued with an IP address from the windows DHCP server on the windows 2000 network - these allocated IP addresses are registered properly on the DHCP server.

However, I need to know which remote PC's have been allocated the various ip addresses as we need to map network drives from our head office to thos remote PC's. Thus I would need to associate that remote PC's netbios name with its DHCP allocated IP address (How can I get it to register its netbios name on our network?). For example: each day that the remote computers connect through the VPN they arn't garunteed to be allocated the same ip address so we have no way of knowing which PC has been allocated which IP address so we don't know what the netbios name of the pc we are connecting to is. A DHCP server or a predefined IP pool are the only way of allocating IP addresses to the remote PC's.

I need to over come this, can anyone help me please. The windows 2000 DNS server address is downloaded to the VPN client but their IP addresses dont seem to be registering with the DNS server and neither are their netbios names..

Please help.

Could you not just assign them static ip addresses?
either via client configuration and researved via MAC address MCSE NT&2K
CCNA/CCDA
CNA
ASE
NSP

Or you could configure 'Reservations' in you r DHCP Scope so that it gets the same IP Address all the time if you don't want to go the Static IP Route (no pun intended)

I am not familiar with Checkpoint firewalls, but others I've used assign the IPs themselves. In those I have seen, you can see the netbios names of the computers connected to the firewall (I am assuming PPTP). I'm not sure how helpful this is, as you might be looking for a more permanent solution.

Some hardware firewalls will allow you to configure the PPTP clients to actually authenticate on the Windows 2000 server on the inside, thus updating the WINS, if you are running it.
