janjangao/forwardproxy repository overview

⁠Forward Proxy

forwardproxy⁠ Forward port with tailscale domain by query. hostname.xxx.ts.net?port=9000

⁠Step

⁠Run forwardproxy with docker

DockerHub: janjangao/forwardproxy⁠

docker run --network=host --restart unless-stopped -d --name forwardproxy janjangao/forwardproxy

docker compose

services:
  forwardproxy:
    image: janjangao/forwardproxy
    container_name: forwardproxy
    network_mode: host
    restart: unless-stopped

⁠Tailscale Funnel on forwardproxy

tailscale funnel --bg 8080

⁠Test locally

For example, you have a portainer deployed on localhost:9000, try access http://localhost:8080?port=9000, you can access portainer as well, the query shall be saved on cookie after first access, next time you only need vist http://localhost:8080 with same browser, if need change forward port, put the query port=5244 in url again.

⁠Access Tailscale domain

https://{yourdomain}?port=9000

⁠Run without host network mode.

By right, container can not access host localhost network, so we need run with --network=host, but container has a bidge IP 172.17.0.1 can access host, so can assign it as default host by env variable. But with this way, you only can access with current host services by port, host parameter shall not be supported. if you are looking for a way to use other service on intranet, for example: https://{yourdomain}?host=192.168.1.7:5244, it still need run with network=host mode.

# 8888 is server port
docker run -p 8080:8080 -e PORT_FORWARD_DEFAULT_HOST=172.17.0.1 --restart unless-stopped -d --name forwardproxy janjangao/forwardproxy

⁠Tailscale in docker

It has same host network accessbility problem(container can't access host localhost), tailscale needs run with --network=host as well.

⁠Query

⁠?port=9000

⁠?host=172.17.0.1:9000

Port forward shall be enough for tailscale funnel, if you want to forward host you can try this

⁠?clear

Clear the forward cookie

⁠?debug
