nat or dhcp

[dntaba]

hi,

i have a content filtering firewall that was handing out
our dhcp addresses. it can only hand out 255 addresses and
we've gone beyond that number of devices.

i have a 2000 server that was in our lab doing nothing
that i'm going to put on the network.

should i turn on dhcp and set the gateway to be the
firewall and the scope to be 192.168.0.1 - x.x.255.255? i
only have one nic and the server is not new hardware.

any advice would be welcomed.

thanks,
dave

You obviously have a DNS server running in that segment.
And I think you will have to turn-off the DHCP software
on the firewall. As two DHCP servers don't gel well

I think you are correct in assigning the gateway as the
firewall. I would set the scope as 192.168.0.1 -
192.168.x.x and obviously your subnet as 255.255.255.0.

I think that should help youI am still very new at
subnetting and routing etc. So forgive me if this is
totally BULL****.

Good Luck.

If you want more than 255 addresses on the subnet,
255.255.0.0 would be a better subnet choice. Don't forget
to exclude any static IPs (including your
firewall/gateway) from the scope.

Good luck.

ok,

thanks everyone.

my plan is to shut down dhcp on the firewall, and then
turn on dhcp on the server with the gateway being set to
the firewall's ip. i'm going to exclude a range for
statics and then i should be fine. i don't need to worry
about nat or about having 2 nics, do i?

thanks again.

NAT should continue to work on your firewall, but you'll
need to verify with the manufacturer.

You don't need 2 NICs for the DHCP server. You would want
two if you were using the W2K box as a router between
subnets or using that server as a firewall/proxy.

Good Luck!

Dave your best bet is to install another nick in the 2000
server and configure it as a router to give out ip
addresses in a different ip range. connect half your
comouters to the new network. configure the server as
default gatewat adn set it's dns to forwarw to the DNS
servers on the router. All packets will still be filtered
and you doubled your available ip addresses and increased
network speed with in home subnets
