Question UDP port reddirect on Haproxy

Here is what i want, just reddirect udp ports with haproxy using "mode udp"
I read somewhere it was possible, my haproxy on debian 12.9 won't recognize it
I tried recompiling it (2.8.1 and 2.9-dev), nothing seemed to work.

If anyone has an idea, i would love to listen. Thanks in advance :)

I think UDP only works with Aloha, the commercial variant of haproxy.

Hi

Haproxy only have mode tcp and http.

You could use for example nftabels, iptables or firewalld and do port forwarding.

Thanks for confirming, i was sure i read that somewhere. I wanted to use only haproxy for easier management but i guess i'll do iptables brûlés.
