How to open terminal port on demand?
 
I have to open terminal connection to windows server over the linux router and it should be safe solution. I can't use vpn (some ISP don't allow VPN connections) and I don't know ip people (they can travel through the world).

Are there solutions which allow to open port RPD on demand within several hours for the necessary IP?

Now I have thought up only one solution:

I can make a small site with https autorization where users can press button which run script (rule for iptables), that open 3389 port only for user IP. And this script make cron job that delete this rule after "X" hours.

It is not smart solution :) But it have to work.
