Greetings, Has anyone gotten a reverse proxy server working with gemini? Specifically, I'm looking for something that can listen on port 1965 and route encrypted traffic to other ports based on the TLS SNI. I don't want to do TLS termination at the proxy-layer because I need to support client certificates on the destination servers. >From my research, it looks like Nginx and HAProxy both claim to support TLS routing like this, but I can't for the life of me figure out how to configure either of them :/ Best, Michael
I am using HAProxy. Here's my config for some inspiration: https://gist.github.com/panda-roux-dev/9142cf01ad3b29aa86120c7cd90d5b95 It was a headache to set up because I'd never used it before and 99% of the search results online are concerning its HTTP usage, but eventually figured out something that works in TCP-mode. Note that I'm using TLS passthrough rather than having HAProxy take care of encryption. This is in order to let each back-end server use certificates with its corresponding domain name listed in them. Good luck. panda-roux On 5/25/2021 1:05 PM, Michael Lazar wrote: > Greetings, > > Has anyone gotten a reverse proxy server working with gemini? > Specifically, I'm looking for something that can listen on port 1965 > and route encrypted traffic to other ports based on the TLS SNI.

I just re-read your message and saw you're wanting SNI-based routing. Bear in mind that the configuration file I sent deals only with domain-name based filtering based on sub-string comparisons. I haven't tried anything else yet. Please let us know if you do get that working though! panda-roux On 5/25/2021 1:30 PM, panda-roux wrote: > I am using HAProxy.

With nginx it's quite simple, just ensure that your nginx is compiled
with stream_ssl_preread_module:
stream {
map $ssl_preread_server_name $upstream {
"app1.example.com" 127.0.0.1:5000;
"app2.example.com" 127.0.0.1:5001;
}
server {
listen 1965;
proxy_pass $upstream;
ssl_preread on;
}
}

Have you tried Traefik? It supports SNI-based routing.

My gemini server at https://github.com/Xe/rhea does reverse proxying. Works with Unix sockets too. It does everything I need.

It would allow your gemini server to do TLS and forward requests to various backends. Info about the client certificates can be sent as parameters. I think it could be a viable option for Gemini, and I started to experiment with it in gmid[0], but further work in needed in this regard.

Thanks for all the helpful suggestions everyone! I ended up going the nginx stream route because it looked the simplest and I'm already familiar with installing and using the software. Everything on gemini://*.mozz.us is now being routed through nginx and appears to be working great. - Michael
