IP Source Routing

I'm still shaky as to how the tmm and the linux kernel interact where routing is concerned, but you can try the iproute package native to the linux kernel:

 

 

ip route add / dev src

 

 

make sure you have a route configured in the bigip.conf file. Note that this will not be supported by F5. I'm doing this for radius system authentication traffic that for some reason is being sourced by an interface other than the one traffic is leaving on.
