Hello,
I am new on zen, but maybe a continous ping can be added in /etc/rc.local
or the start script in zen folder ? This may be a workaround waiting for
the new feature

Hi, it is a know issue with some firewalls. Zen sends gratuitous arp
packages to the broadcast when cluster switches to force the ARP table to
be updated but some firewalls require a direct ICMP packet to update the
ARP table, as you reported it is your case.
We are going to develope this property 'send ping packets to the gw if the
zen switches' for future releases.
Thanks for your report.

Hello Emilio,
yes Juniper is the gateway. I also forced the first
After the connection to the load balancer is not more reachable from the
other location, the LB2 switched automatically to LB1.
I tried then a ping from both load balancer to the Gateway. The both pings
was continuous possible.
After the pings the we got an email from our monitoring system that the
load balancer is from the other location again accessible.
Between the first e-mail that the load balancer wasn’t reachable and now
reachable is (1 minute later after the ping) are 43 minutes.
I didn’t forced the second load balancer to switch to the first load
balancer.
This was tested with the option force the second load balancer as a master.
I activated now the maintenance mode and will do the tests ask you asked
and inform you.

Hi Roger, sorry for the late response, I have been checking your logs and I
have detected your cluster service is switching, I would require you
confirm that you problema appears when the cluster service switches so
could you run some test forcing the master node to maintenance?
Once you confirm you lose the access to the service from juniper ( I guess
juniper is your gw), I would require you run ping from your active zen
server (node2) to the gw (juniper), and confirm if one you run a continuous
ping the problem is solved..

Hello Emilio,
did you found something out?
I shut down the second load balancer (for the cluster) and we got no more
notification from our monitoring system that the load balancer isn’t more
reachable.
Maybe that helps you.

Hello,
today morning we got messages from our monitoring systems on other factory
location that the ZenLoad Balancer isn’t more reachable.
In the local network the Load Balancer was accessible.
We restarted for test purposes the Juniper firewall. The access from the
other factory location was then possible.
I attached a Wireshark dump.
We noticed an option in the Juniper. Maybe this causes problem?

What are we wondering that the access was over the entire week possible and
now we get from one day to the other day this problem.
Were we should at best search for errors?
