Hello Chris,

 

 

First of all thanks for responding!

 

 

The issue was that even though the LTMs and the DB servers are on the inside, the network admin had blocked the traffic between the 2 using the FWSM (as they are in separate VLANS).

 

 

When I tried to connect to the Database using the LTM CLI, I was unable to do so. That is when I found out that the traffic is being blocked.

 

 

Now, after the necessary rules have been created it is working fine.

 

 

Secondly, to explain my scenario, there were 2 APP Servers for the inside users being Load Balanced by the LTM's plus 1 APP Server in the DMZ for the internet users.

 

 

It was required to base the availability of APP Servers in both these zones (inside & DMZ) on the DB availability, which is why I needed to run the DB monitors on the GTM (for the DMZ APP Server) and after getting the network admin to open the traffic between the GTM and the NAT IP of the DB Servers in the DMZ the monitors are running on the GTMs also.

 

 

Thanks for your response once again.

 

 

Cheers,

 

Mansab.
