Hello,
I am attaching a very simple network map to this post to illustrate what I am trying to accomplish. I recently acquired a Cisco 2911 router. We have a 192.168.1.x/24 network, but we have run out of IP's. We are also moving to a new suite, and I figured I could run a fiber line between the suites, connect a switch to give both suites connectivity to the same network. Furthermore, I can create a /22 network and migrate servers/machines to new network at my leisure with near zero down time. I seem to have hit a brick wall. I factory defaulted the 2911 config. Next I set a username and password for router and enabled telnet. Next, I gave interface gi0/0 ip address 192.168.1.176. This should now join the router to the current network. I gave interface gi0/1 ip address 192.168.100.1 255.255.252.0 which should open the inside interface to the 100.x network which it did. I ran into an issue browsing the internet etc due to no NAT, so I nat'ed everything through the gi0/0 interface, and I can remote desktop from my 192.168.1.112 machine to the 192.168.100.100 server, can ping it fine etc. However through the 192.168.100.100 server I can't ping out to 8.8.8.8 from anywhere. When I'm consoled into the router I can ping everything everywhere fine from the router.
Could someone please take a look at my ip route statement and my config and guide me where I'm going wrong? I have tried a wealth of settings/configs and can't seem to get this to work.
Thank you.
IP Route:
sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, + - replicated route
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S* 0.0.0.0/0 is directly connected, GigabitEthernet0/0
192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.1.0/24 is directly connected, GigabitEthernet0/0
L 192.168.1.176/32 is directly connected, GigabitEthernet0/0
C 192.168.100.0/22 is directly connected, GigabitEthernet0/1
192.168.100.0/32 is subnetted, 1 subnets
L 192.168.100.1 is directly connected, GigabitEthernet0/1
