UDP Radius Client - Need Source IP

Hi,

 

 

Since the LTM preserves client source address by default, you likely have the LTM set up in a SNAT or "one-armed" configuration. If you are in a flat network, without SNAT, the packets will take an asymmetric path as I described in this post: Click here.

 

 

iRules can insert headers, but since there's no way to do an X-Forwarded-For header for RADIUS that I'm aware of (like there is for HTTP), your only choice may be to rearchitect the network such that the LTM is the default gateway for the RADIUS servers and you can remove the SNAT and go back to the default of preserving client source IP.
