Problems with routing

[DucAnhLe36058]

Hi,

I've got a problem with routing and I can't seem to figure out where the problem is. I am able to ping from PC0 and PC1 to PC3, from PC3 do Cisco1, but I cannot ping from PC0 or 1 to Cisco 1. It's the same on the other side, I can go from PC4 to Cisco2, but I can't go to Cisco1. 

Cisco 1 ip route:

ip route 0.0.0.0 0.0.0.0 172.18.0.2
ip route 192.168.30.0 255.255.255.240 192.168.30.2
ip route 192.168.30.48 255.255.255.240 192.168.30.34

Cisco 2 ip route:

ip address 192.168.30.34 255.255.255.240

All the IP addresses and default gateways I believe are set up correctly.

Hi @DucAnhLe36058 

At first glance, the routing looks ok.
Review the gateway theme assigned to PCs.
If you are working with physical devices, try disabling PC firewalls.

ip route 192.168.30.0 255.255.255.240 192.168.30.2  appears to be wrong because first it doesn't encompass the entire network of PC1 and PC2, and second you are routing the traffic to a PC not a router.  You would need to change PC3 to a router and change the route to "ip route 192.168.30.0 255.255.255.228 192.168.30.2" or enable/configure Windows Routing Service on PC3.

Hello,

not sure if the other posts have already solved your problem, but it seems to me that you only need the following routes:

Cisco 1

ip route 0.0.0.0 0.0.0.0 172.18.0.2
ip route 192.168.30.48 255.255.255.240 192.168.30.34

Cisco 2 

ip route 0.0.0.0 0.0.0.0 192.168.30.33
