Re: Dynamic DNS registration port

If your computer attempts to get an IP from a DHCP server outside your
network, it will not attempt to register its DNS record with your DNS server
in your office unless you have your DNS server set statically on your
workstation.

Also, you said port 53. It needs to be UDP port 53. Also, if you open your
DNS server to allow dynamic updates unsecured from the internet, you are
opening yourself up to a host of possible DoS attacks and other security
issues. I cannot think of a "need" to have your workstation registered on
your internal DNS server unless you are doing something beyond normal remote
work.

What is your exact need because if you only allow remote DNS registration
and Kerberos authentication, you still cannot get to shares or printers.
Are you even asking about a firewall for remote connectivity or just between
segments on your internal network?
