RRAS VPN client cannot connect to local network

Question

Hello everyone,
I have a problem while setup a VPN server using RRAS.
I have a server RRAS which have 2 network card: LAN (10.0.0.56/24) and WAN (IP from ISP). WAN have default gateway to connect to Internet. LAN doesn't have default gateway.
Client after connect to RRAS server can go to internet, but cannot go to 10.0.0.0/24 I cannot ping PC 10.0.0.23, 10.0.0.24 or any PC on subnet 10.0.0.0/24 except 10.0.0.56 which is IP LAN RRAS
The subnet assigned to VPN client is 10.0.34.0/24
My question is how can I config VPN client connect to subnet 10.0.0.0/24?
Here is routing table on RRAS (sorry I cannot upload picture):
Destination networkmask gateway interface metric protocol
10.0.0.0 255.255.255.0 0.0.0.0 lan 281 local

And in routing table on VPN Client I don't see any route about 10.0.0.0/24. When I use tracert 10.0.0.23, the first row appear is 10.0.34.3 and then Request timeout. 10.0.0.34.3 is the IP beginning of subnet assigned to VPN Client.

Does anyone help me this issue? I'm so grateful about this.
