I have a server with 2 NIC's. Is it possible to enable the Windows firewall
on just one of them ? If not, should I install RRAS ? I just need the
server to have internet access for anti-virus updates--it doesn't host any
web apps or anything.
 
Re: Windows firewall

It is not a good idea to enable two NICs in any machine without a reason.

I find this an odd question. What is the other NIC connected to? Doesn't
that network have an Internet connection? How do the machines on that
network get anti-virus updates?

You only need to install RRAS if you want the server to be a router or a
remote access server.

Re: Windows firewall

It's an odd configuration. I have no choice. The other nic is connected to
workstations which also have 2 nics. The "other" nic in them is connected to
a network which has i/n access (same network as the "other" nic in the
server).
However, I have zero control over that network. I just need to firewall one
nic and not the other. So, is it possible with Windows firewall ??

Re: Windows firewall

What stops working if you enable the Windows firewall? You should be
able to enable local networking. It is not uncommon for a server to access
local resources with the
firewall active.

Re: Windows firewall

The server is, basically a SQL and File/print server. When I turned the
firewall on, both of these roles quit working. Then, in doing some research,
I found the general feeling is that it is a bad idea to run Windows firewall
on a 2003 server. I also remember seeing what ports to open if you really
want to run it but don't seem to find that info now. Can you direct me to a
document which has this info ??

Thanks

Re: Windows firewall

If you are concerned about it, simply disable the Internet connected NIC
at all times except when you want to run Windows update.
