+# IPv4 Proxy
+
+This project aims to serve those without an IPv6 ISP by forwarding IPv4 requests to the
+correct destination. This is accomplished by SSL preread and port mapping. This service
+is intended only for publicly accessible services.
+
+## DDNS
+
+This project pairs with the ddns service. Set that up first!
+
+## Updating IPv4 Proxy Records
+
+1. In `ddns` create a new record in the `reeseapps_record_template.json`
+2. Apply the new record with ansible
+3. Update `vars.yaml` in this project
+4. Run the following ansible script:
+
+```bash
+ansible-playbook -i ansible/inventory.yaml systemd/graduated/ipv4-proxy/nginx.yaml
+```
+
+## Logging
+
+You can tail all the nginx logs with `ssh yellow 'tail -f /var/log/nginx/*.log'`
