Inbound load balancing Link controller or LTM and DNS

HI, I have a LTM and GTM modules for do a link controller, all the traffic outbound is work fine, but the client have an applicattion that I need to do a load balancing for the inbound request.

 

I have configured:

 

listeners

 

190.x.x.2

 

157.x.x.82

 

Links

 

190.x.x.1

 

157.x.x.81

 

VS

 

190.x.x.6:443

 

157.x.x.85:443

 

this IPs are the applicattion

 

I have a GSLB pool relation with the IPS of VS

 

I have a wiide ip--> wip.ec.midominio.com type of register wideip--> A

 

But not work when I try to access to this url this not work and I check the listener and I don't have any statistic

 

The client have this configuration in DNS

 

wip.ec.midominio.com in ns lc1.ec.midominio.com

 

wip.ec.midominio.com in ns lc2.ec.midominio.com

 

lc1.ec.midominio.com in a 190.x.x.6

 

lc2.ec.midominio.com in a 157.x.x.82

 

join.ec.midominio.com in cname wip.ec.midominio.com

 

All the object in f5 are with acircle green.

 

What is mistake in the configuration? and do you know if after to configure wideip I need to wait for any time to refresh the results?

    Hi, I don't know if you made a mistake about name server lc1 and address:

    listeners: 190.x.x.2 lc1.ec.midominio.com in a 190.x.x.6

    Anyway, if you could run command "dig" or "nslookup" directly to listeners, whats happen?

    e.g.

    dig @190.x.x.2 wip.ec.midominio.com

    dig @157.x.x.82 wip.ec.midominio.com

    or

    nslookup
server 190.x.x.2
wip.ec.midominio.com

    What the result?

    If it get works, you must check if outside can reach that listeners, or maybe correct the name servers addresses, or something else.

    Regards.
