I've got the 4-port BEFSR41 and I'm not using the DMZ function on it.
Didn't think I needed to since I had the ISA server and could use its
DMZ function if needed. The linksys is only being used on the external
interface of the ISA server and I've forwarded ports 25, 80, and 443
of the ISA server to it. I haven't forwarded any ports from the mail
server because I haven't figured out how to publish it yet.
