Hi,

the DHCP Server is installed on the TMG Server?
http://technet.microsoft.com/en-us/library/cc302605.aspx (you can use this article also for Forefront TMG)

Did you create allow rule for DHCP?

Yes DHCP Server installed on TMG server

Right now I created Firewall Policy for DHCP (reply) and DHCP(request) for all networks to all networks

As Marc noticed, you have to create rule for DHCP (local host <>vpn clients)

Right now I created Firewall Policy for DHCP (reply) and DHCP(request) for all networks to all networks

Don't forget to start Log Query (Log&Reports-Logging-Tasks-Start Query). You can use filter if it's necessary. Provide yo

Now I changed it to DHCP (local host <>vpn clients) but same problem

witch filter in query I should apply?

Just review your log on any errors (red records) or apply filter "Action is equal Failed". VPN client is now receiving APIPA address not DHCP. Please, make a screenshot with your created rules or provide the full description (source network,target,action,protocols and etc)

this is my created rules :

DHCP Reply = FROM Local host to VPN CLIENTS

DHCP Request = FROM VPN CLIENTS to Local Host

Ok? Your rule is not c

No any new Status, same problem,

I made 2 rules for DHCP as you say

by the way when I change Address assignment to External work fine IP range 192.168.55.xx to clients

but I need my internal range

DHCP configured correctly?

Are you getting any alerts in the Log query?

You can add some rules just for test (all outbound traffic between local host+vpn clients to local host+vpn clients)

Provide your results. 

Can your provide your networks list and networking rules?

I don't think problem is in TMG access rules and VPN connection,

I think VirtualBox Network settings have problem, and it should be change

Hi,

Thank you for the post.

You should check you vpn settings on TMG server as per this guide:http://www.isaserver.org/articles-tutorials/configuration-general/Checking-Out-TMG-2010-Virtual-Private-Network-Server-Part1.html
