It's depending how you are giving your (pool)addresses to clients.


Supose your gateway has 192.168.1.1 and you own a class-c-net (/24),
your RAS-Server has 192.168.1.2
and your pool ranges form 192.168.1.10-192.168.1.42 (so IN the range of the gateways default net).
If now a client logs in he will get an from the pool (like 192.168.1.23/32).
All packets from the client (to internet) will go to your RAS-server and (due his default server to the gateway)
If packets come from the Internet they first reach your gateway. Due to the netmask the gateway will send out an
ARP-request the get the hardwareaddress of 192.168.1.23. If you have Proxy=active the RAS
server will see this and answer with HIS hardware address so that he get's the packet
and forward it to the client because the client isn't really in the local LAN.
If you don't want to use this your gateway needs an extra route that points all pooladdresses to the RAS-Server
(as you have to do if the pooladdresses are outside the LAN)

Hope this makes it clear....
