DHCP conflict ( ASL vs WIN2000 )

hi 21,
In my network i've 3 DHCP server ( win2000 ), i've assigned a scope by dhcp and a range of dynamic ip ( eg: from 172.16.100.50 to 172.16.200.150 ).

now i need to assign dhcp ( from 172.16.100.1 to 172.16.100.49 ) to my VPN user ( PPtP roadwarriors ) .
in this configuration i've some internal network client that takes dynamic IP from ASL dhcp and not from my W2000 server !!

How to prevent this ??

follows my ASL DHCP setting :

network: PPTP poof on internal
range: from 172.16.100.1 to 172.16.100.49
DNS: my internal DNS server
WINS: my internal WINS server
node type: H-node
No Gateway
NO static mappings

probably the real question is:
if a Roadwarrior need to take an IP of the same internal network class when connecting from remote client through VPN ( to be reached from internal net via VNC, browsing, etc.. ), my configuration setting are right ??

how to prevent internal network clinet to take IP from ASL DHCP ??

Roadwarriors are usually assigned IP ranges from a block outside of your internal LAN.  (Hence the PPTP-Pool address range).  They don't have to be though.

I assume you have setup "PPTP Roadwarrior Network Access" in Astaro.  You should not need to run the Astaro DHCP server at all.

Use your existing Win2K boxes for internal DHCP. (Perhaps make your scope smaller, or exclude a portion of the scope for your roadwarrior users.)

Then in PPTP Roadwarrior Network Access, use appropriate network values so PPTP users get correct IP's.

How many PPTP users do you have ? Could you assign each user an IP ?

As stated earlier, don't use DHCP on Astaro.  Just use the PPTP Roadwarrior Network Access functions.
