I expect your help by giving clue how to achieve the traffic as described below: (Also find the attached Diagram)
It is a Hub & Spoke topology. Branch office-1 is able to communicate with Branch office -2 thru Hub Router. Now I want to change the traffic flow such a way that if Branch office-1 wants to communicate with Branch office -2 traffic should go to Firewall which is placed behind the Hub Router (Pl. find the attached Diagram) do all the security check and then allowed to reach Branch office -2 .The same is applicable vice versa.
Putting in simple words, Inter Branch office traffic should pass only thru Firewall and not directly using Hub Router itself.
Hope you will share your valuable ideas and discuss
