Is it possibe to run N8N on a homeserver using docker under debian. Is it a problem that the homeserver is located behind a DSL router? Can it anyway integrate with services like gmail, chatgpt etc?
It looks like your topic is missing some important information. Could you provide the following if applicable.
- n8n version:
- Database (default: SQLite):
- n8n EXECUTIONS_PROCESS setting (default: own, main):
- Running n8n via (Docker, npm, n8n cloud, desktop app):

Welcome to the community 
You can definitely run n8n in an isolated environment with no ingress, but you won’t be able to use the webhook node or any trigger nodes that use webhooks. Gmail and ChatGPT should work fine without any issues.
I you wish to use webhook based triggers, you could setup ngrok or Cloudflare tunnel to get a public endpoint that forwards the traffic to your private instance.

I suggest you look into cloudflare tunnels. Super easy to setup. Result will be a subdomain for n8n which can be access secured from outside … and integrate with the services you mentioned.
