DNS and natd

[Scott Hiemstra]

I've never tried it with natd on freebsd but I have on many routers just
setup a loopback adapter which will allow your hosts which are inside to
loopback into the webserver.  I searched through the docs but I can't seem
to find a specific example.  Perhaps someone here has some experience with
this setup.

-Just as an example, my home web hiemstra.us is actually served by
192.168.1.20 on my LAN.
-I don't have any funny DNS going on to get there.
-My router figures out I actually need to get to 68.165.225.111 and routes
the requests through the loopback
-I get the desired page delivered

I'm not 100% sure this is feasible in freebsd but it should be.

Good luck,
Scott

Thanks for your reply. I found the "6.1 Creating a mini-DNS system" document
from the Pedantic PPP Primer
(http://www.freebsd.org/doc/en_US.ISO8859-1/books/ppp-primer/c831.html#AEN83
3)

Do you think it fits my needs?

Yes, it is an internal DNS setup and I believe "views" requires BIND9. With
BIND8+, you need two DNS setups: 1 for external and 1 for internal
(LAN).....
