NimbostratusX-Forwarded-For on L4 VS
Hello again guys,
I'm involved in a specific configuration these days. We have a simple virtual server configured in TCP mode that dismounts into a web service. So far, there was no specific requirement but I have been notified that they need to know the real IP of the clients connecting for statistical purposes.
Right now, between the balancer and the end nodes there is a snat, I had thought of configuring an x-forwarded-for, but as it is a tcp virtual server I think it is not possible.
Is there any alternative to solve this problem?, or is it necessary to replicate the virtual server in HTTP mode?
Thanks
Best regards
Hi Martin182,
There are two possibilities to solve this:
1. Configure the virtual server as standard and apply an http profile with x-forwarder-for " the most simple".
2. Configure the F5 as a router with a couple of Virtual Servers 0.0.0.0/0 for TCP and UDP and make the Self-IP in the server's network of the F5, the default gateway for servers and avoid snat, it allows servers to reach outside through the F5.
Hope it works.
