Thanks a lot Stuart, you pointed me to the right direction. We are using Wildfly. I added
a new interface and added a second socketBinding as you have described. That works nicely.
Really cool, the interface can be configured to listen on a nic name too. This is exactly
what I am looking for.
What I didn't manage is only to open the management console. What is the path for
accessing the management console? I saw in some tests "/mod_cluster_manager" but
I was not able to access the console with this path.
I think, it would make sense to update the official wildfly undertow load balancer
documentation:
https://docs.jboss.org/author/display/WFLY9/Using+Wildfly+as+a+Load+Balancer
Thanks again
Ralf

Are you using Wildfly or standalone Undertow? The procedure for configuring a listener is
different for each. For Wildfly just add a socket binding to the interface you want to
listen on then add a http-listener in the Undertow subsystem that references that
binding.
For standalone Undertow simply call addListener() multiple times for each interface you
want to listen on.

Subject: [undertow-dev] Frontent Load Balancer with Mod-Cluster using a virtual IP
address
Hi
I trying to replace your Apache Httpd with mod_cluster load balancer with
Undertow frontend modcluster as part of Wildfly 9.0.1.
It works fine when I define a 'real' IP address defined in /etc/hosts:
127.0.0.1 localhost
10.22.62.40
mdzhrnesir01.standard.six-group.net mdzhrnesir01
But this IP address 10.22.62.117 is not taken by untertow:
ip addr
.
8: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP
link/ether 00:17:a4:77:f0:b6 brd ff:ff:ff:ff:ff:ff
inet 10.22.62.40/24 brd 10.22.62.255 scope global bond0
inet 10.22.62.117/24 scope global secondary bond0
I also faced to problem, that running the example presented by Stuart Douglas
doesn't work inside a docker container. Even I execute step by step.
Without digging into the source code, what are the criteria under which
Undertow frontend modcluster accepts IP address(es)?
Do you also have a proposal for configuring Undertow modcluster to listen to
two interfaces? Say an internal IP address and an virtual external IP
address?
I think with Apache, we defined 0.0.0.0 and then Apache with mod_cluster was
listening on all interfaces, if I remember correctly.
Thanks a lot in advance
Ralf
