In my office, we have routers that serves as access points and they are all connected to a dumb switch which gets its connection from a PC which serves as a server that has  2 ethernet ports. One of the ethernet port houses our Local lan that runs services while the second ethernet port houses our internet connection.

In my office, we just newly got an internet connection and I would love to use OpenDNS to restrict websites especially Youtube and Facebook.

Before now, we have  services running on our local LAN with IP address on 192.168.0.1, 192.168.10.1, 192.168.11.1 and our internet IP LAN IP address on 41...., 

I tried configuring the OPENDNS on our server following instructions on this website but it still does not work. 

How do I configure OPENDNS to work?

 

Summary of my network is.

A PC that serves as Server with 2 Ethernt Port.

Our local service runs on one of the ethernet port and the other port houses our internet connection

These two ethernet ports has LAN's that goes into a dumb switch which distributes network to routers that acts as access points.

How do I configure OPENDNS to work on our network?

  You do not use OpenDNS Home, because as a busniness you are not licensed for it.
  Instead you use https://umbrella.cisco.com/products/packages

  Regardless, currently you use your ISP's gstelecom.com DNS service, because the Umbrella (= OpenDNS) resolver addresses are not configured at least on the device behind 192.168.10.1 or later.  This is where you must configure the resolver addresses, ideally on the WAN facing side, i.e. as forwarder addresses.
