I use a server for my extended family and friends and require a dyndns block/allow feature which allows access to the server to only these people via a specific port. I've noticed this already implemented on the port forwarding section on the option called "Src Address", problem is it only allows access to for 2 dyndns and ip address's which isn't anywhere near enough what i need. So i would need something which allow me to place has many dyndns address has i require, to only allow these people to access that specific port

Feature rejected. Two dynamic DNS is sufficient for a home router. "Unlimited" parameter is bad programming practice to support "as many as required".

ok! is there a way to at least remove the limit placed on the "Src Address" to an amount that would be useful to me?

Maybe by adding a script or changing some option?

use an online service to amalgamate all your ddns into one place, there are many. No need to add this to the router.

cool! i've looked but i haven't found anything that works… it doesn't do what i want… these ddns companies seem to limit stuff to their own accounts. The problem is these dyndns are given to me… i have no control of what dns companies are used…

SO. basically i need a ddns account plus a program which will recieve the updated ip of any dyndns, no-ip, easydns etc… their own dyndns accounts or whatever other companies are updated by them not me… So i recieve their already updated ip and forward these ip's to my own ddns account to block anyone else other than these people from accessing the port… do you see what i mean? is there anything that does that?
