Hello. I am working on a school project and I am very new to networking in general. I have a small network simulation made in GNS 3 with 3 routers (Cisco c2691) connected to each other. Here is the set up below:
My problem is that I am getting Internet on R1 but not on R2 and R3. I cannot even ping 8.8.8.8 from R2 but doing so from R1 works. All of them are routed through OSPF. Here are the configurations of R1 and R2 respectively:
R1:
! ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname R1 ! boot-start-marker boot-end-marker ! ! no aaa new-model memory-size iomem 5 no ip icmp rate-limit unreachable ip cef ! ! ! ! no ip domain lookup ip auth-proxy max-nodata-conns 3 ip admission max-nodata-conns 3 ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ip tcp synwait-time 5 ! ! ! ! ! interface FastEthernet0/0 ip address dhcp duplex auto speed auto ! interface FastEthernet0/1 ip address 192.168.0.254 255.255.255.0 duplex auto speed auto ! interface FastEthernet1/0 ! interface FastEthernet1/1 ! interface FastEthernet1/2 ! interface FastEthernet1/3 ! interface FastEthernet1/4 ! interface FastEthernet1/5 ! interface FastEthernet1/6 ! interface FastEthernet1/7 ! interface FastEthernet1/8 ! interface FastEthernet1/9 ! interface FastEthernet1/10 ! interface FastEthernet1/11 ! interface FastEthernet1/12 ! interface FastEthernet1/13 ! interface FastEthernet1/14 ! interface FastEthernet1/15 ! interface Vlan1 no ip address ! router ospf 1 log-adjacency-changes area 1 virtual-link 192.168.0.1 area 2 virtual-link 192.168.0.2 network 192.168.0.0 0.0.0.255 area 0 ! ip forward-protocol nd ! ! no ip http server no ip http secure-server ! no cdp log mismatch duplex ! ! ! control-plane ! ! ! ! ! ! ! ! ! ! line con 0 exec-timeout 0 0 privilege level 15 logging synchronous line aux 0 exec-timeout 0 0 privilege level 15 logging synchronous line vty 0 4 login ! ! end
R2:
! ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname R2 ! boot-start-marker boot-end-marker ! ! no aaa new-model memory-size iomem 5 no ip icmp rate-limit unreachable ip cef ! ! ! ! no ip domain lookup ip auth-proxy max-nodata-conns 3 ip admission max-nodata-conns 3 ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ip tcp synwait-time 5 ! ! ! ! ! interface FastEthernet0/0 ip address 192.168.0.1 255.255.255.0 duplex auto speed auto ! interface FastEthernet0/1 ip address 192.168.1.254 255.255.255.0 duplex auto speed auto ! interface FastEthernet1/0 ! interface FastEthernet1/1 ! interface FastEthernet1/2 ! interface FastEthernet1/3 ! interface FastEthernet1/4 ! interface FastEthernet1/5 ! interface FastEthernet1/6 ! interface FastEthernet1/7 ! interface FastEthernet1/8 ! interface FastEthernet1/9 ! interface FastEthernet1/10 ! interface FastEthernet1/11 ! interface FastEthernet1/12 ! interface FastEthernet1/13 ! interface FastEthernet1/14 ! interface FastEthernet1/15 ! interface Vlan1 no ip address ! router ospf 1 log-adjacency-changes area 1 virtual-link 192.168.0.254 network 192.168.0.0 0.0.0.255 area 0 network 192.168.1.0 0.0.0.255 area 1 ! ip forward-protocol nd ! ! no ip http server no ip http secure-server ! no cdp log mismatch duplex ! ! ! control-plane ! ! ! ! ! ! ! ! ! ! line con 0 exec-timeout 0 0 privilege level 15 logging synchronous line aux 0 exec-timeout 0 0 privilege level 15 logging synchronous line vty 0 4 login ! ! end
I tried doing NAT on R1 as follows:
R1(config)# int f0/0 R1(config-if)# ip nat outside R1(config-if)# ex R1(config)# int f0/1 R1(config-if)# ip nat inside R1(config-if)# ex R1(config)# access-list 100 remark R1(config)# access-list 100 permit ip 192.168.0.0 0.0.0.255 any R1(config)# ip nat inside source list 100 interface f0/0 overload
But that did not help either. Is there any way to get internet traffic in R2/R3 and every other network connected to it? Any help would be really appreciated as I have tried every possible way I know of.
