Need to connect multible networks to public network

[Lucif3r]

In this scenario I am using 4 kind of different networks  for each block.  block A can communicate to public network bcoz of Nat on Pat configuration in router A, I want access the internet from block b ,block c, block d ,if i configure Nat on Pat in router b means can I possible to connect public network from block b router (  block b to isp)
Or does I want to buy another ISP connection for block b

Note
In this scenario i am using eigrp routing protocols, dhcp configuration, unequal cost path load balancing

ISP router to block a static route

Block a to ISP router default route

Moved to homework help...

I'm going to say that if all the blocks are in the same building or even city, you will want to use the one Internet connection.

However, would having routers other than Router A handling NAT/PAT be desirable? What would Router A do with a NATted address? Would it route it properly?

Four routers placed in same campus
Yea I can able to communicatete with other networks  I am using eigrp protocols for Routing.
Yea Nat on Pat configured in router A, router A was converted my private address into public address
It's work gud

My question is I want to access internet from router b

Does I need to configure Nat on Pat in router b

Well, router B has to send traffic to router A to use the Internet. Wouldn't router A's NAT rule also apply to traffic from other parts of the network passing through router A?
