DHCP

[Ken B]

I have a RRAS server, with 3 modems in it for dialin. I'm not concerned
with VPNing, so I decreased the number of ports from 5 to 1 and unchecked
the "Remote Access Connections (inbound only)" checkbox. So the server
lists the only ports available for a connection to be made are 3 US Robotics
56k modems (com1, 3, and 4). If I look in my DHCP server at the leases,
there's 10 addresses leased to the RRAS server, all expiring at the same
time, type DHCP and Unique ID "RAS". Why's there 10 addresses instead of
just 3? I can have at most 3 dial-in connections at a time, so why's there
more??

Help!! My scope's running a lil low!

You really need 4, not 3. The server uses one itself and one for each
remote client.

The number of addresses RRAS leases from DHCP is set by a registry
setting. But the simpler approach is to use the static address pool. Give
the pool four of your IP addresses and reserve these in your DHCP scope.

Well, assuming the server is given it's own static address, there should
only be 3 entries for leases for it in dhcp. I think I'll take your advice
and make it a static address pool. It should release those 'leases' right
away after I do that (and make those 3 addresses part of the exclusions
list), right?

Thanks for a quick reply, Bill

No, the server needs an extra IP to act as the server end of the ppp
connections. It appears in the RRAS console with the name internal.
