H'lo Bob, |
32 |
|
33 |
I'm not a DNS wizard though (with help from friends) I have DNS running |
34 |
locally/publicly. While my environment is not exactly the same as what |
35 |
you describe, it has lots of similarities (which I realized as I wrote |
36 |
the description below).... |
37 |
|
38 |
The DNS configuration has several zone files. One is for my |
39 |
192.168.x.y LAN. A second is for osagesoftware.com. The third is for |
40 |
bogofilter.org. |
41 |
|
42 |
My LAN has multiple machines, with a variety of operating systems and |
43 |
distros. There are appropriate entries for each machine in the LAN zone |
44 |
file. FWIW, each machine has a static IP address. |
45 |
|
46 |
osagesoftware.com's zone file has multiple entries, i.e. www, ftp, |
47 |
mail, etc which all resolve to one machine. |
48 |
|
49 |
bogofilter.org's zone file also has multiple entries. |
50 |
|
51 |
The DNS machine has 2 NIC's - one for connecting to the LAN's switch |
52 |
and the other for connecting to the WAN (internet). The WAN card |
53 |
responds to two static IP addresses (one each for osagesoftware.com and |
54 |
bogofilter.org). |
55 |

HTH, |
