Firewalls and MagnaVoIP
Data102's MagnaVoIP service uses two networks for geo-redundancy and a restricted set of ports for the various offered services.
We strongly recommend that customers firewall based on subnet rather than IP due to potential changes to configurations in the future. That said, subnets are fixed and will not change.
