### (Work Around) Deployment on Ubuntu 22.04LTS using docker behind `ufw`
Basically, docker automatically manage your iptables if you use the port-mapping option, i.e., `--publish` for `docker run` or `ports` in `docker-compose.yml`. This means you do not need to manually expose your port, e.g., 443 TCP/UDP for HTTPS, using `ufw`-like management command.
However, we found that if you want to use the brand-new UDP-based protocol, HTTP/3, on `rpxy`, you need to explicitly expose your HTTPS port by using `ufw`-like command.
```
% sudo ufw allow 443
% sudo ufw enable
```
Your docker container can receive only TCP-based connection, i.e., HTTP/2 or before, unless you manually manage the port. We see that this is weird and expect that it is a kind of bug (of docker? ubuntu? or something else?). But at least for Ubuntu 22.04LTS, you need to handle it as above.
### Other TIPS
