How use Surveys when CRM behind Firewall

I keep my CRM behind a firewall.

In Campaigns, there is an ability to use a Proxy to monitor email responses and unsubscribes.

I do not see a similar setup in Surveys.

I have looked at the Forum and Googled “SuiteCRM Survey firewall” but no luck.

I did see numerous comments about adding &contact=$contact_id to the Survey URL string to capture the actual Contact Name for the Survey responses and I want to include that as well.

How can I use a proxy - like in Campaigns - to capture the results of a Survey AND include the Contact Name responsing to the Survey so I can see in the Survey Report and the Contact Subpanel, who has responded with what response?
