Hi.
Let's look at a scenario when any UDP port gets blocked for some time after sending\receiving some amount of traffic.
But each time you make a new connection to a new port, you can still send some data.

I suggest implementing a port range option for peers with de-muxing the transport connection between multiple ports.

[Interface]
ListenPort = 10000-20000

[Peer]
Endpoint = 1.2.3.4:10000-20000

Next step would be making multiple connections and stagger them in time.
For each of multiple connections peers pick a random port number from specified range. When one of the connections gets blocked, packets would seamlessly go through another one.
When a dead connection is detected, peer makes a new one on a random port from the range.

Even better, if you could specify multiple IP's if your server has them.

[Peer]
Endpoint = 1.2.3.4:10000-20000, 5.6.7.8:15000-20000
Connections = 4

I've done some tests on a vibe-coded tunnel and it works even if you manage to send only a couple of kilobytes per connection.
