I am a network admin at a company. So my company has Two SITE, A and B, and we are using internet from our ISP of 4 MB via optical fiber.
My IP are; 10.1.5.x with a subnet mask os 255.255.252.0
I'm using a Cisco Router 2800 series for the internet connection perimeter and just before my lan I got a Cisco ASA 5520, this is on Site A..all these equipment are correctly configured and working properly, as they were configured from the company where we bought the machines.
But as we got two Sites, therefore we bought as well two other Cisco router 2800 series and a Cisco ASA 5520, which I have to configure it at SITE B.
OBS; I got approx. 150 PCs on Site A and about 100 on Site B, all connected to my lan and internet, and on a dedicated domain.
My problem is that I'm kind of new to the ASA business and ain't got much experience.
So how can I configure the router and Asa on site B?
How does the configuration have to be set accordingly to the Site A configuration...so that both ASA and maybe routers can communicate each other?
How to configure the Routing protocol? The NAT, PAT etc and how can I implement VLAN on them, so i can segregate PCs from different departments so they don't see each other and don't send to others unnecessary traffic or broadcast?
Here is a SHOW RUN config from the ASA on Site A

I'm honestly sorry if my query may look simple, but I'm really worried about it.
So can anyone please, please do help me on this particular issue.
Update: What I want is to know is how I can make the two ASA 5520 plus the router 2800 communicate among them on the network? Please note that the two site are communicating already through the fiber optic connection.. but what about the other Asa 5520 and the router? Is the site to site IPSEC VPN the solution for them to communicate safely? How can I make it happen? How the configuration must be like.. remember as i said, the Sites are already communicating via the optical fiber connection... so from one building I can read and write on a file... so my problem is that now I'm left with another Asa 5520 plus a router 2800 for the other Site to be configured.. however what must I do? and how?
