The remote access machines do not get their config from DHCP. They get it
from the remote access server itself as part of the PPP negotiation. The
RRAS server leases IP addresses from DHCP to use for the clients and the
internal interface (which is the server end of the PPP connection).
The config on the remote client looks right to me. It has the correct
DNS address and its IP address matches the LAN machines and its gateway
address is the "received" IP address. That is also correct. It indcates that
the default gateway is the PPP connection.
Is your LAN using a switch? The method you are using (called on-subnet
addressing) goes back to RAS in NT and relies on proxy ARP. There is no real
routing between the remote client and the LAN machines. The client sends
packets to the server through the PPP connection and the server puts them on
the LAN. The server then listens for replies and uses proxy ARP to receive
replies addressed to the remote client, which it then relays over the PPP
link.
This all works fine on hubs and most switches. Some switches don't
handle the proxy ARP and it just doesn't work. The best solution in that
case is to use off-subnet addressing. Instead of using DHCP, put the remote
clients in their own IP subnet using the address pool option in RRAS and
route the traffic through the RRAS server.
