[SR-Users] Kamailio behind HAProxy

[Joey Golan]

Maybe I miss understood you.
For local installations you mean HAProxy with transparent mode?

I have a functioning setup without proxy protocol enabled but without anitflood enabled because all traffic comes from same HAProxy address.

I’m not sure I understand the purpose of tcp_accept_haproxy. When and how this parameter should be used?

Thanks,
Joey.
