Hi Gavin,

If I got this right I think you might be on the wrong track. Here is how
this works:

- if you set up a static pool then remote clients will be distributed IP
address from that pool. The clients will also get the DNS settings from the
settings of the RRAS server
- if you set up DHCP to allocate the IP addresses THEN the clients will get
the DHCP settings. As Bill said previously RRAS leases 10 addresses at a
time from DHCP and keeps them in the registry. It then leases them to remote
clients. When it finishes these 10 addresses it will lease 10 more and so on
and so forth.

The fact that you set up the DHCP relay does not mean that clients will use
DHCP, because you already set up a pool of IP addresses to be assigned to
remote clients. If you want DHCP to assing your IP addresses to remote
clients remove the static pool and select DHCP from the following: under the
remote server's properties in RRAS mmc, go to the IP tab and make sure you
select 'Dynamic Host Configuration Protocol (DHCP)'. Then if your DHCP
server is on the same subnet as your remote server you do not need to use
the DHCP relay. However if your DHCP server is on a different subnet then
you need to set up the DHCP relay otherwise remote clients will never be
able to reach the DHCP server.

Hope this answers your question.

Cheers,
