Firewall needs/settings for running standalone Snowflake proxy

Hi there,

I’m trying to set up a snowflake proxy on a vps, but I am not having luck finding any info on firewall requirements. I’m not sure experienced with NAT and would appreciate a little guidance as to what to do. I have the docker image up and running and accepting connections, but have shut it down until I figure out how to secure the proxy.

It’s set up with the sole purpose of running this proxy and is not hosting any other services.

Thanks in advance.

The firewall needs to have the UDP ports 32768-60999 open and reachable from the proxy.

Hi meskido,

Thanks for your quick reply.

I ended up allowing all outgoing connections (and blocking all incoming). From looking at the docker logs it seems to be working?

I do wonder why there so much more outbound than inbound traffic, though.
