Multihomed addresses

[BruceO]

Hi,
I have a Linux box with three nics that I use as a firewall.
I haven't previously needed DNS set up locally, but now I do.

In linuxconf the nics are:

eth0 main.bordway.org 10.0.0.1
eth1 sub1.bordway.org 172.16.1.1
eth2 sub2.bordway.org 192.168.1.1

I started to put addresses into my db files & my brain locked up.
Any examples of zone files with entries for multihomed boxes?

Thanks,
Bruce
