Ext - DHCP v RAS DHCP

[The Ricster]

In my continuing effort to make at least one successful
VPN connection, I am wondering if using RAS to assign
ip's to VPN clients is better than using my routers DHCP
service to do so.

Currently, I point the DHCP Relay Agent to the internal
IP of my router (which is also the gateway ip), and it
seems to be working, since the client can connect (but
can not see the lan), and receives an IP address
consistent with my lan. I am assuming that this will make
the client part of my lan subnet.

But maybe the DHCP from the router is missing something
that the RAS DHCP can supply, like maybe WINS or the
address of my internal DNS server, or something that will
allow the client to see the rest of the network
(including the RAS server resources, which it does not
now.

Any ideas...anyone...please...

I doesn't make a lot of difference which way you do it. The client in
fact gets its IP address and the WINS and DNS addresses from the VPN server,
no matter which way you do it.

The IP address and name server addresses come to the client as part of
the PPP/PPTP negotiation at connection time. So they come directly from the
RRAS server, not from a DHCP server. If you configure the RRAS server to use
DHCP, what actually happens is that the RRAS server leases a batch of IP
addresses from the DHCP server, and uses these addresses as its address
pool. The client should receive the WINS and DNS addresses which are
configured on the RRAS server's LAN NIC.
