Does HAProxy support UDP?
I am attempting to retrieve SonicWall firewall logs in my syslog manager via HAProxy. However, SonicWall only sends logs using UDP, so I’m unable to receive the logs. can anyone help me on this ?

2

Will upgrading HAProxy from 2.2.9 to 2.3 help solve the issue of not receiving SonicWall logs over UDP? And will this upgrade impact my existing HAProxy configurations?

no, haproxy does not support udp, only tcp and http

4

Is it impossible to route UDP traffic through HAProxy? Can I use LVS with Keepalived to address this issue, is that help?

Haproxy does support forwarding syslog messages via UDP and TCP since 2.3.
