I have 2 subnets like this: one host is 192.168.0.55 connected to the default GW of 192.168.0.110 which is the first leg of the RRAS server. the second one is 10.1.1.2. two legs belong to RRAS 2008. to the second leg conected DC 2008 with ip 10.1.1.1. my goal is to ping from my host 192.168.0.55 ---> 10.1.1.1. Unfortunately i have no ping. what is my problem??? 10x.eternals81

Routing will work if both machines use the router as their default gateway and IP routing is enabled (ie enable LAN routing in RRAS). 192.168.0.55 dg 192.168.0.110 | 192.168.0.110 RRAS 10.1.1.2 | 10.1.1.1 dg 10.1.1.2 Ping depends on the firewalls allowing ICMP echo. Either allow ping in the firewall settings of both machines or temporarily disable both firewalls.Bill

thanks it is working now. but i have another issue. my vpn client that resides on my windows 7 192.168.0.55 won't get any dynamic IP from my DHCP server that resides on dc 2008 ip=10.1.1.1, instead he keep getting this ip=169.254.254.190 from server 169.254.121.122 which is i guess my Radius client(192.168.0.110 or 10.1.1.2). why is that?eternals81

A VPN client cannot get its IP directly from DHCP. It gets its IP address from the VPN server as part of the connection negotiation process. It could not work any other way because the IP is only valid for the duration of the connection, not for the lease time of the DHCP server. If the server is set to use DHCP for remote clients, it is the server which leases a batch of addresses from DHCP. It uses one for itself (for its "VPN" interface, which is the internal interface in RRAS) and allocates the others to clients as required. If your VPN server cannot get IP addresses from DHCP, you can always use a static pool of addresses. Bill

thank you very much.eternals81

But my question is where is the DHCP server would be installed and how many DHCP servers exist in my environment? 10x.eternals81

How could we possibly know that when we know next to nothing about your environment ? Have you installed a DHCP server? If so, where is it and how is it configured. Bill

Yes, DHCP server is installed on RRAS. It is configured usually to lease ip addresses to my windows 7 machine.eternals81
