Hi Jarno,
thanks a lot for your hint. I had two issues. I missed "mode tcp" also in the
backend and additionally your tip works perfectly without acl but with the
"use_backend special if {src 10.0.0.1 10.0.0.2} " statement.Thanks Philipp -- ----------------------------------------------------------------------- DI Mag.

Is it something you can get from layer4 (src,src_port,dst,dst_port) or something from for example SMTP protocol ? > Has anyone a tip how to achieve this with mode tcp? If you can get special host from layer4 then for example: use_backend specialhost if { dst 10.10.10.10 } might work. -Jarno -- Jarno Huuskonen
