+/**
+ * These tests use two Geode sites:
+ *
+ * - One site (the remote one) consisting of a 2-server, 1-locator Geode
cluster.
+ * The servers host a partition region (region-wan) and have gateway senders
to receive events
+ * from the other site with the same value for hostname-for-senders and
listening on the
+ * same port (2324).
+ * The servers and locator run each inside a Docker container and are not
route-able
+ * from the host (where this JUnit test is running).
+ * Another Docker container is running the HAProxy image and it's set up as a
TCP load balancer.
+ * The other site connects to the locator and to the gateway receivers via the
+ * TCP load balancer that forwards traffic directed to the 20334 port to the
locator and
+ * traffic directed to the 2324 port to the receivers in a round robin fashion.
+ *
+ * - Another site consisting of a 1-server, 1-locator Geode cluster.
+ * The server hosts a partition region (region-wan) and has a parallel gateway
receiver
+ * to send events to the remote site.
+ *
+ * The aim of the tests is verify that when several gateway receivers in a
remote site
+ * share the same port and hostname-for-senders, the pings sent from the
gateway senders
+ * reach the right gateway receiver and not just any of the receivers. Failure
to do this
+ * may result in the closing of connections by a gateway receiver for not
having
+ * received the ping in time.

Review comment:
It was not possible before the fix for #5701 but as that is now in
place, I have been able to reduce the max to 15 secs.

> Ping not sent to the right gateway receiver endpoint when several receivers

> Key: GEODE-8656
> URL: https://issues.apache.org/jira/browse/GEODE-8656
> Project: Geode
> Issue Type: Bug
> Components: wan
> Reporter: Alberto Gomez
> Assignee: Alberto Gomez
> Priority: Major
> Labels: pull-request-available
>
> When several gateway receivers have the same value for hostname-for-senders
> (for example when running Geode under kubernetes and a load balancer balances
> the load among the remote servers), the ping messages sent from the gateway
> sender client are only sent to the receiver (endpoint) to which the sender
> connected first.
> The other receivers will not get the ping message which will imply that the
> connections towards them will be closed after the configured timeout expires.
> This ticket is a continuation of the work done ticket GEODE-7565.
