They say everybody is a n00b on some subject. IOS is one of many such subjects for me.
Here's the situation: I have a Cisco 2620 running 12.3(26)c. FastEthernet0/0 is the onboard 10/100 interface, and is hooked to my private network (10.22.0.0/24). FastEthernet1/0 is the 10/100 interface on a NM-1FE-TX WIC, and is hooked to my ISP's network (obscured here as 71.x.x.x). My config is as follows:
no aaa new-model ip subnet-zero ip cef ! ip dhcp excluded-address 10.22.0.1 10.22.0.100 ip dhcp excluded-address 10.22.0.200 10.22.0.254 ! ip dhcp pool mypad network 10.22.0.0 255.255.255.0 dns-server 22.214.171.124 126.96.36.199 default-router 10.22.0.254 domain-name mypad.mydomain.net ! ip audit po max-events 100 ! interface FastEthernet0/0 ip address 10.22.0.254 255.255.255.0 ip nat inside duplex auto speed auto ! interface FastEthernet1/0 ip address 71.x.x.x 255.255.255.0 ip nat outside duplex auto speed auto ! ip nat inside source list 1 interface FastEthernet1/0 overload ip http server ip classless ip route 0.0.0.0 0.0.0.0 71.x.x.254
Everything is working just peachy, but there's one problem: I can't get through to a fair number of hosts, particularly ones in the 69/8 space. We'll use car-part.com (188.8.131.52) for example - try to access it from behind the Cisco, no go; connect the outside connection directly to one of my machines and try it, all good.
Right now my main issue is identifying the problem specifically. Once that's done, I (obviously) need to resolve it.
Anyone willing/able to give me some direction here?
