I have a problem on my network where the internet connection is intermittent.
The first visit on the page shows page cannot be displayed and you have to refresh it in order to show.
under chrome it says server DNS address could not be found.
It is resolving after I refresh the page several times.
I have attached my network diagram for you to understand more in details.
The IP address on diagram is not the actual IP configured on my network..
Basically I have two gateway
gateway 1 : for the Internet (10.0.153.11)
gateway 2 : for the corporate links, page, AD replication, etc. (10.0.152.1)
where these two gateway are connected to a core switch.
this core switch routes any requests to a particular gateway
route 10.0.0.0 0.0.0.0 10.0.152.1 - any ip starts from 10 will point to corporate router or gateway2
route 0.0.0.0 0.0.0.0 10.0.153.11 any ip will point to gateway 1 or access internet
client PC is configured as
Subnet : 255.255.252.0
IF I change the DNS to 184.108.40.206 (LOCAL ISP DNS) internet works perfect however, if I ping any hostnames of my servers or client PC
I got 220.127.116.11 which means there is a collision on IP.
DC that act as DNs server with IP 10.0.152.18 and forwarders are configured with the local ISP and google ISP
Please see the details in diagram

Can you tell me where the problem is? consider the internet on firewall is working properly when directly connected.
