Does anyone know if it is possible to load balance ESP traffic. I have
server running the Apani client which encrypts all traffic between the
servers. A few of the servers currently have apps being load balanced.
Whenever the Apani client is enabled you cannot get to the app using
the virtual ip address. You can get to the app using the real ip
address. My thinking is the switch sees the ESP traffic hit the
virtual ip and does not know what to do with it. I tried to fix this
by enabling layers 3 load balancing and using a service of ip(Example
Below). Just curious if anyone else has run into this .

/c/slb/virt 1
        ena
        ipver v4
        vip 10.1.54.247
        layr3 ena
/c/slb/virt 1/service ip
        group 1

Usually, for a basic SLB, Alteon only use source and destination port
to share traffic.
The encryption of traffic is usually done at layer 7, which means it
never encrypt layer 4 source and destination port.
So, I think there is something wrong of your setting, not because of
the encryption.
