I have a working dns (bind9) and dhcpd running on my home lan. This adds dynamic dns updates from dhcpd to bind9.

The following is mostly based on http://www.semicomplete.com/articles/dynamic-dns-with-dhcp/. Kudos til Trygve Laugstøl for assistance too :)

I currently have an OpenBSD firewall running on an ancient 586. I have a mini-itx board, CF/IDE converter and a CF card and have been intending to upgrade.

However - rather than OpenBSD I'm going to try for debian (since I know that much better).

This post will end up being a "how I did it" - but at the minute is just a collection of the notes I'm grabbing for now.

The dnslookup section of the exim4 config contains

# ignore private rfc1918 and APIPA addresses
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 : 192.168.0.0/16 :\
172.16.0.0/12 : 10.0.0.0/8 : 169.254.0.0/16

To allow one specific subnet thru change it:
# ignore private rfc1918 and APIPA addresses
ignore_target_hosts = !192.168.3.0/24 : 0.0.0.0 : 127.0.0.0/8 : 192.168.0.0/16 :\
172.16.0.0/12 : 10.0.0.0/8 : 169.254.0.0/16

Here it allows the 192.168.3.x network.
