I have set up a network with 3 offices on 3 different subnets.
File available at, https://github.com/turntheairblue/packetTracer
Router configuration is as follows,
I have fully configured Office 1 as labeled in the picture below. Offices 2 and 3 are not fully configured yet, only the routers are configured.
I'm using the laptop in Office 1 to ping each router. I can ping all devices in Office 1 without any dropped packets. I can ping the 172.16.32.1 gateway on the Office 1 router without any dropped packets. I can ping 10.0.0.1 on the Office 1 router without any dropped packets.
Here is the issue, when I ping 10.0.0.2, 188.8.131.52 and 184.108.40.206 on the ISP router, I get 1 reply and 3 dropped packets for each address.
When I ping 220.127.116.11 and 18.104.22.168 I get no replies.
Another thing, if I shut off the 22.214.171.124 and 126.96.36.199 interfaces on the ISP router I can get 4 replies from the 10.0.0.2 interface.
I can't seem to figure out what the cause of this is? Is it something to with my IP addressing scheme? I'm fairly new to networking in general, I'm assuming I have made a noob mistake somewhere along the line!!!
