Nat port with dynamic source

[marcvb]

Wat are we trying:

We want to give us the option to be able to open a port for the public ip where we are at the moment.
We can use VPN but that is to much overhead.

What have i tried.

I created a nat rule with a alias as source.
This alias is filled from a webserver, created a desktop application to update the webserver.
Only the alias updates each 24 hours, not instant or each minute.
I can change the script for pfsense to get it each minuten, but i fear it will put to much stress on the firewall.

Maybe you guys have a better idea.

I think you need to rewrite this post with more detail??

But from what you have above could you not just have an alias with a group of internal webserver addresses or a designated subnet (assuming only one internal address will be using the nat rules at any given time)
