- Add nginx stream configuration on reverse-proxy to forward port 2222 to apps:22 - Update firewall rules to allow port 2222 for Git SSH access - Configure Forgejo to use SSH_PORT = 2222 for Git operations - Add comprehensive SSH forwarding research documentation - Enable Git operations via git@git.geokkjer.eu:2222 Phase 1 implementation using nginx stream module complete. Ready for testing and potential Phase 2 migration to HAProxy.
