Cisco 2621 router config issue
I've been slamming my head against this for the last few hours, and am
hoping I can get some help from you guys. :) At the moment, I have a Cisco 800 series operating as my main router. The router in question is a Cisco 2621xm with the ipbasic IOS. FastEthernet0/0 is assigned an IP address of 10.0.1.101. FastEthernet0/1 is assigned an address of 192.168.0.1. FE0/0 is plugged into the 800 series. That router is my home gateway, and has an IP of 10.0.0.1. From the 2621xm, I am able to ping the main gateway, as well as external IP addresses. My laptop, which is connected to FE0/1, can not. I assigned it a static IP address of 192.168.0.101. Any thoughts and hints are much appreciated. Thanks! Current configuration : 880 bytes ! version 12.3 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname password ! boot-start-marker boot-end-marker ! enable secret 5 password enable password password ! no network-clock-participate slot 1 no network-clock-participate wic 0 no aaa new-model ip subnet-zero ip cef ! ! ! no ftp-server write-enable ! ! ! ! interface FastEthernet0/0 ip address 10.0.1.101 255.255.254.0 ip nat outside duplex auto speed auto ! interface Serial0/0 no ip address shutdown ! interface FastEthernet0/1 ip address 192.168.0.1 255.255.254.0 ip nat inside duplex auto speed auto ! interface Serial0/1 no ip address shutdown ! ip classless ip route 0.0.0.0 0.0.0.0 10.0.0.1 ip http server ! ! line con 0 line aux 0 line vty 0 4 password password login ! ! ! end |

I see you have a / 23 as your network for Fe0/1. Can your laptop ping its own gateway? |

I agree with the above posters, or you can start NATing on the second router as well (which can make things more complicated, but would probably fix the immediate issue). Regardless, the internet gateway router does not know how to get back to the 192.168s. |

And a second thought I had. Will the gateway NAT 192.168 to the internet, especially since it is probably not in its dhcp/nat pool and not directly connected? The OP may need to check the gateway router to ensure this would work. |
Re: Cisco 2621 router config issue
Brian was spot on. I needed to add a route to 192.168.0.0 on the 800
router. That fixed everything. Thanks again! |
