Use Original_Dst filter in UDP Proxy filter config

[Jianyong Niu]

Hi All, 

I need help on configuring a dynamic forward proxy for udp traffic.

While running envoy v1.32.0 on linux using the following config I ran into an error reading 

[2024-11-08 14:39:12.653][104152][debug][init] [source/common/init/watcher_impl.cc:31] init manager Server destroyed
Didn't find a registered implementation for 'envoy.filters.listener.original_dst' with type URL: 'envoy.extensions.filters.listener.original_dst.v3.OriginalDst'

This error appears to be UDP filter only. For TCP filters it works ok. 

Below is my test config. Thanks!
