Update:
Loadbalancing is working now with l4xnat DNAT (I can reach the server and
clients), but the gui is still showing pending connections in Real Server
Status and farm overview. (Using the patch "networking_functions.cgi" Sept 2014
I received from you showing the connection status in farm view of l4xnat farms)
I am not sure if this is an error of the gui or if there are connections not
going through.
How can I track that? It want to make sure that everything is working...
Thanks,
Christian

Betreff: [Zenloadbalancer-support] l4xnat farm setup for DNAT
Dear Mailing list!
I am using Zenloadbalancer community edition 3.05 to load balance Lync2013
Frontend servers.
Until now I used l4xnat NAT for all protocoll types and it worked fine. The
problem is that I am not able to see the incoming client IP-address.
So I switched to l4xnat farm with DNAT and all protocolls with the following
network setup:
Client NET: 10.53.1.x
ZenLoadbalancer VIP for Client access: 10.100.1.205
ZenLoadbalancer IP Backend network: 10.101.8.1
Backend Servers network: 10.101.8.x GW 10.101.8.1
Zenloadbalancer Cluster IP eth0:1 10.100.1.204
Table interfaces:
Name Addr
eth0 10.100.1.206
Physical IP Node1
eth0:1 10.100.1.204
Cluster IP
eth1 10.100.1.205
VIP Service
eth2 10.101.8.1
All network traffic for the backend network (10.101.8.x) is routed via the core
routers through the Cluster IP of the Zenloadbalancer (10.100.1.204)
Now my problem: When I try to access the service I see mostly pending
connections, some established connections. The service is not usable. If I
switch back to NAT everything is working.
I think there may be a routing problem...
Is this setup okay? How can I trace the reason for pending connections?
Thank you for your help
best regards
Christian
