Re: Is Windows 2003 firewall safe?



My bad, I forgot ISA06 beta has not quite ended.

What do you mean by "The ISA version you mention is dated"?

Thanks again.

Layers are nice, but you rule that out in final comment.
It is always best to not place critical infrastructure right
on the edge / external network.

The ISA version you mention is dated.

The W2k3 firewall is good at what it does and it will cause all
inbound traffic to the external interface to be dropped except
for what you state to allow, if you configure it correctly.
In your case I would use both the firewall and IPsec in a
filtering isolation mode.

I want to setup Windows 2003 + Exchange 2003 server with to network
adapters: one for the intranet, and the other for the internet.

Is it safe to use Windows 2003 built-it firewall on the external adapter
to block everything but mail and dns ports (53, 25, 110, etc)? If not,
can I install ISA 2004 firewall to protect it (i.e is Exchange 2003
compatible with ISA in the same machine?)

Ideally it would be better to have an external firewall but I can't
afford it ($$$).

Thanks!
