How Can I Obtain the Real IP Address of a Visitor?

Layer-7 (HTTP) load balancers automatically obtain real IP addresses of visitors using the X-Forwarded-For HTTP header. This function is enabled by default and cannot be disabled.

Layer-4 (TCP) load balancers require the TOA kernel module to obtain real IP addresses. For details, see Configure the TOA Plug-in.
