nPath is nice feature in F5

F5 Networks

I have been looking for DSR for a long time. As our load balacing is one armed. Source Nat is a must. But some applications need to track the original source IPs. Brocade uses DSCP for this. Backend servers need some special customization to support this. Also the network devices in the network paths are required to support this.


Netscalar just requires the network topology to support DSR.


F5 uses IPIP tunnel to achieve DSR. Most of the backend servers can support this. So it is very nice feature.

Interesting, never thought to combine a tunnel with nPATH.


I assume you've looked into X-Forwarded-For for Web applications?

We load balance many applications other than web applications. Some of them need to track source ips.
