I have a home office network in which I need to setup a DNS server to
resolve lookups for computers inside the LAN. My setup is as follows:
External Sonicwall VPN Firewall running DHCP for internal computers. I
port forward traffic to internal servers for publicly available
services. I am running a FC2 webserver on one internal LAN computer
and a Windoze box that is running a mail server appication. I forward
port 80 traffic from the external ip address to the internal webserver.
I am hosting websites for different 6 domains. The publicly available
dns is hosted on a dns service provider for the domains in question.
What I am looking for is the ability to resolve the internal ip
addresses to each of the websites which I am hosting while not becoming
authorative for the whole domain, else I would disable my ability to
send mail to the domains which I do not host mail services.
How do I add what are essentially A records for domains which I am not
authorative for to point to the internal ip address of my websites
while not having to re-create the mx and miscellaneous other A records
which resolve to outside network servers for the domains in question?
My current setup was created with webmin and the caching-nameserver
rpm. I am running BIND 9.2.3 on a FC2 bix running webmin 1.140. My
setup currently has the following entries in the webmin interface:
rootzone defins to point to rootservers
masterzone 127.0.0.1:
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
1 IN PTR localhost.
masterzone localhost:
$TTL 86400
$ORIGIN localhost.
@ 1D IN SOA @ root (
52
3H
15M
1W
1D )
1D IN NS @
1D IN A 127.0.0.1
I have my ISP's dns servers addresses entered in the Forwarding and
Transfers section for dns forwarding.
Please let me know what I need to do to setup my dns in the manner
described or let me know if I left out any pertinent information.
