Currently, ZeroShell does not have support for DDNS updating of the forward and reverse DNS mappings from DHCP. This is due to a limitation in the LDAP backend that ZeroShell uses for the DNS database. There is, however a script that was written to resolve this problem. I have not used it yet, but I am looking into trying it out on ZeroShell one day. I was wondering if it would be possible to implement this existing script into ZeroShell to allow DDNS updates automatically.
This script can be found on the Bind 9 LDAP backend home page, or at the link below:

I think this would be awesome to not have to worry about trying to assign static entries would be awesome!
