Yeah - been a while - got distracted by non-tech.

George Toft, have not seem you in a while. Thanks for all this feedback.
Eventually I will configure DNS on my private net.
Love your parental controls!!
I hope to configure a home server in the future. The first time it
was so I could say I did it. The second time (future) I hope to learn
a lot more and I would like to have the bragging rights.

Short answer to all of your questions is yes, you can do this. I did
it for several years, and it came in really handy when I wanted to
control the Internet usage of my pubescent children.
I set up DNS locally - I used georgetoft.com and had it split -
outside my house (public) only had the simple entries for the A, MX,
CNAME records. Inside my house, I included the file server, FTP, web
and mail server hosts.
Then I set up a DHCP server that issued my DNS server's IP as part of
the DHCP response. That way, everyone in the house could access the
internal resources.
Now when my teenage children got the hormones and thought they knew
more than me, I set up two different DHCP configs and used cron to
activate one profile in the daytime and a different one at night. To
make this work, I turned off DHCP and WiFi on the Internet Gateway
and used my own DHCP server and WiFi Access Point, with a TTL of 60
seconds. At the appointed time, the nighttime profile kicked in
which only allowed the approved MAC addresses to get a DHCP address,
effectively cutting them off from the Internet both by their PC and
their phones. They were out of high school before they figured out
how to make their phones into hotspots - LOL.
As far as running your own mail server - yes you can (and I did for a
while), but the effort really isn't worth it. Back when I would get
1 or 2 SPAM per week, and took great delight in tracking down their
mail provider and ISP and filing SPAM complaints, but when it ramped
up to 50/day, I outsourced it to a provider that managed SPAM
blocking. I tried blacklisting entire countries by IP - that
helped. I tried subscribing to blacklists - that helped, but in the
end, I had more important things to do than spend hours per week
managing an email server.

Hi,
For some reason .local popped into my head this morning. From what
I read it appears I may be able to create an Intranet that has a
private domain name such as MyBusiness.local, on a private IP, and I
am thinking I can run BIND and make a zone file for this Intranet.
In this case, if I am in he local net I can bring it up with
MyBusiness.local?? If so then I should be able to add subdomains to
the local BIND/zone... So will this private network work like the
public Internet?
This makes me believe I can create a mail server on this private net
for the users of this private net. Not that I want to, however it
is interesting.
I read that MAC is doing something with the .local domain so it was
recommended to use:
.test
.example
.invalid
.localhost
Would it be possible to create a private network using one of these
private TLDs and can I use BIND to control this?
How will my browser know to go to my private domain if I use one of
these private domains - I seem to recall needing to put this in the
hosts file on Linux and Windows so it would resolve. Would BIND
override this?
Thanks!!
Keith
