Changing WAN IP address from DHCP to static without console access

[VasilyK]

Hello,

I am running pfSense on amazon aws ec2 instance and do not have access to the console.

How I can change WAN IP address from DHCP to static without rest of disconnecting in the middle of the process?

Currently, I am using web interface to manage it.

My thoughts were running a script or creating a snapshot, restoring it into volume and modifying some files after attaching it to a different instance and then attaching it back.

If your ISP is providing DHCP, why would you want to do that? You could be inviting problems.

It is not ISP, the instance is running on amazon EC2.
It looks like I can change it via GUI, but a bit worried if something will go wrong and I will not able to connect to it.

It was not possible to change it correctly from gui.
I have connected to console using putty change IP of the interface and later created new gateway via gui and assigned it to the network card.
