(b) Figure 2(d) depicts a network where two subnets - 192.168.1.0/24 and 192.168.2.0/24 are configured with private IP addresses while the rest of the network (including a server farm) are using public IP addresses. Both FastEthernet interfaces of Router1 are configured with the last usable interfaces of the networks while the Serial interface is configured with 98.51.66.21. Dynamic NAT has been configured for the subnet 192.168.1.0/24 while Port Address Translation (PAT) has been configured for the subnet 192.168.2.0/24. The partial running-config file on the Router3 is as shown in Figure 2(e). 80.25.25.100/24 Server-PT Web Server 192.168.1.0/24 se Cloud-PT Cloudi 2960-24TT Switch0 Server-PT Serveri 30.1.1.1 2960-24TT Switch1 GRE BA 2960-247 Switc 2 192.168.2.0/24 Figure 2(d) interface FastEthernet0/0 ip address 192.168. 1. 254 255.255.255.0 interface FastEthernet0/1 ip address 192. 168. 2. 254 255.255.255.0 interface Serial0/1/0 ip address 98. 51. 66.21 255.255.255.0 Figure 2(e) Fa0/0 Fa0/1 Router-PT Router1 Seo/1/0 Router-PT Router2 Se0/2/0 30.1.1.100 Router-PT Router3 Fa0/1 Server Farm Server-PT Server4 30.1.1.4 Server-PT Server2 30.1.1.2 Server-PT Server3 30.1.1.3
