3proxy - HTTP, HTTPS and SOCKS Proxy Server

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

3proxy is a lightweight, tiny proxy server that provides HTTP and HTTPS forward proxying and a SOCKS4/5 proxy in a single small daemon. This image delivers it fully installed and running under systemd, so a working proxy endpoint is listening within minutes of launch, with no manual compilation and no configuration required to get started. The HTTP and HTTPS forward proxy listens on port 3128 and the SOCKS proxy on port 1080, both managed by systemd for automatic restarts and clean logging.

Unlike a bare deployment, this image is configured to be secure by default and is deliberately not an open relay. There is no default password baked into the image: a unique proxy username and password are generated on this instance's first boot and never shipped inside the image. Proxy authentication is enforced, so an anonymous or wrong-password request is rejected with HTTP 407 and carries no traffic. The default access control list allows authenticated clients only from loopback and the private RFC1918 ranges, followed by a deny-all rule, and HTTPS CONNECT tunnelling is restricted to the standard TLS ports so the proxy cannot be abused to reach arbitrary destinations. The operating system ships fully patched with unattended security updates enabled.

Use 3proxy to give applications a controlled, authenticated egress point, to reach the internet through a single hardened hop, to add a SOCKS proxy for tools that need one, or to build a small private forward-proxy tier. To serve clients outside the instance, widen the access control list to your own client CIDR in the configuration file and open the matching port in your security group, as described in the deployment guide. The current release available is 3proxy 0.9.7.
