I have a quick question about using dyndns in tomato 1.27. If I selected dyndns, there is a check box named: Code: Save state when IP changes (nvram commit) What does that exactly mean? Say we select the check box. So is that means, it saves the current IP in nvram and after a reboot cycle, if router gets the same WAN IP, it doesn't change the IP in dyndns name server? On the other hand if I don't select the check box, will it update my WAN ip in dyndns name server regardless what happened to WAN IP after a reboot cycle? OR....is this means something completely different?
