[j-nsp] strange issue

[james list]

Dear experts

My customer has the following very simple infrastructure:



Internet - Firewall – Lan - Load balancer – Lan – hypervisor- VM



It happens sometime that the VM do not respond anymore to Load balancer for
external ip addresses until on the Load balancer it is setted to source NAT
(SNAT) the internet traffic and then SNAT it’s removed.

Something like an action that solicit the VM to refresh the arp.



While health check from Loadbalancer to VM in the same LAN subnet never
stops to work.



Does anybody ever encountered the same problem on VM environments ?

Any idea ?



Thanks in advance

James
