Symmetric nat detection and connectivity support

A server device comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• detecting, by the server device, whether symmetric network address translation is employed at a site comprising one or more computing devices,
• wherein the site is remote from the server device and the server device is coupled with the site via a network,
• wherein detecting whether symmetric network address translation is employed at the site comprises establishing at least two different network connections with the one or more computing devices and comparing one or more of:
• IP addresses associated with the at least two different network connections, and port addresses associated with the at least two different network connections.
• wherein differences between the IP addresses and differences between the port addresses indicate employment of symmetric network address translation at the site;
• and
• in response to the server device detecting that symmetric network address translation is employed at the site, adding, by the server device, a site identifier associated with the site to a site list in order to apply a control policy to the site,
• wherein the control policy directs internet protocol (IP) traffic for the site to a hub configured to serve as an intermediary manager of a data connection between a computing device of the one or more computing devices and at least one other computing device associated with at least one other site, and
• wherein the hub is remote from the server device and the site, and wherein the server device is coupled with the hub via the network.

A method comprising:

• detecting, by a first computing device, whether symmetric network address translation is employed at a site comprising one or more second computing devices,
• wherein the site is remote from the first computing device and the first computing device is coupled with the site via a network,
• wherein detecting whether symmetric network address translation is employed at the site comprises establishing at least two different network connections with the one or more second computing devices and comparing IP addresses and port addresses associated with the at least two different network connections,
• wherein differences between the IP addresses and differences between the port addresses indicate employment of symmetric network address translation at the site;
• and
• applying, by the first computing device, a control policy to the site in response to detecting that symmetric network address translation is employed at the site;
• wherein the control policy directs internet protocol (IP) traffic for the site to a hub configured to manage a data connection between a computing device of the one or more second computing devices and at least one other computing device, and
• wherein the hub is remote from the first computing device and the site, and wherein the first computing device is coupled with the hub via the network.
