I have a client that self hosts on AWS and now they want to move towards HA, easy enough. However the SIP providers they use only connect to IP and not FQDN endpoints.
My thought was to configure an instance as a firewall on AWS, then in the event of of a fail-over dynamically update the firewall to change port forwarding to the secondary server. So there would be 3 instances involved , the firewall and 2 3CX instances.
Has anyone experience with updating an AWS firewall programmatically? If so how much time and effort was it? Will this work?
