[c-nsp] Loadbalancing on ACE4710

[Arne Larsen / Region Nordjylland]

Hi all

I'll appreciate if someone could give me a hint how to setup a ACE4710.
I have a problem regarding RMI calls.
The vendor would like to install 4 serveres with 4 incarnations of the same application.
Say fram tcp port 8001 to 8004.
The client software calls port 8003, so the balancer has to translate the destination port when balancing. Beyond that the client also calls a rmi portrange.
Setting up the port src nat is straight forward I guess.
But how to I control the rmi calls, will stikiness be able to do this based on the scr addr  ?
Do I need an entry more class map pointing out the tcp protocol ?.

Config .:
