Re: SBS Hardware Firewall 2 NICs How To Configure

If I understand this correctly, the Linksys is being used as a perimiter
firewall and the SBS box, having 2 nics is also being used as a secondary
firewall between the Linksys and the rest of the internal network. The
"external NIC, the one that connects to the LinkSys box should be configured
with a static IP in the range of 192.168.1.2-99. It is NOT necessary to turn
off DHCP in the Linksys box unless you're connecting it to the INTERNAL
network but then if you were you'd only have one NIC in the server and you
wouldn't have a secondary firewall ISA or not.
Internet<---->[Linksys]<--->[SBS box]<--->Internal network client PC's
You'll have to use Port Forwarding on the Linksys box for any services you
wish to host on the internet. I.E. you'll at least want to forward port 25
for email, Ports 80 and 443-444 for RWW and maybe even 110 if you have any
POP3 clients. If you want remote admin or VPN you'll need to forward those
ports also. DO NOT configure the SBS server on a DMZ, only forward the ports
you need.

I think Pop is not being as clear as you may need him to be
First of all, you don't indicate if your SBS box is Standard Edition or
Premium with ISA installed and configured?
The main thing here to understand that:
a) The NIC connected to your LINKSYS router/firewall must have a static
IP in the range to match the LAN side of the Router (Probably 192.168.1.2
if that range has not been modifed)
b) DHCP must be turned off on the LINKSYS router
c) It must be in a completely different subnet from the LAN connected nic
(which is no problem if you let SBS select it during install)
Then you should configure the Firewall to pass port 25, 443, 444 and 4125
(at a minimum) to the external nic.

Thanks for your post. The website link does not show the hardware
firewall
between the internet and the sbs box so I stil am not sure how to set all
the
ips and such.

I have a Linksys Router and a SBS box with 2 NICS and static IP. I am
not
sure on the configuration. The router will get the static IP. What
does
the
external NIC get for IP, subnet, gateway and wins. What does the
internal
get
for IP, subnet gateway and wins?
