Tutorial: Caddy (Reverse Proxy) + Let's Encrypt Certificates + Dynamic DNS

[Monviech (Cedrik)]

Well think about it for a second how the proxy should receive the traffic if the firewall blocks it beforehand.

[NeoDragon]

I understand that, but i thought Caddy was listening from 80 and 443 and sending proxied UDP data from specified port to the specified local ip/port, like it's doing with basic reverse proxy.

Is there any advantage of using L4 if you're still opening the game server ports?

[Monviech (Cedrik)]

A remote client would contact the 2000 something port though, not 80 or 443.

The L4 module is if you wanne load balance or multiplex, or want to transform IPv6 from the outside to IPv4 on the inside. Advanced usecases, not just a simple port forward.
