I'm trying to setup a home lab to study for a Cisco certification. My problem is I'm tired of having to physically plug the console into a different device every single time I want to configure it by CLI. So what I've decided to do is setup 5 simultaneous telnet sessions to these devices. (4 switches, 1 router).
So here is my topology:
PC --> Motorola Cable modem --> R1 --> S1 --> S2 --> S3 --> S4
So basically my cable modem will be connected to both my PC and R1. I'm doing it like this so I don't have to connect my PC to R1 and thus lose internet whenever I need to study.
My PC's IP is dynamically from the Motorola cable modem and R1's IP is statically assigned in the same network. This is subnet 192.168.0.0/24. R1's IP is 192.168.0.155
My PC is 192.168.0.2, the cable modem is 192.168.0.1
R1's interface that faces S1 is 192.168.254.254... S1 is 192.168.254.1... S2 is 192.168.254.2, etc.
I'm able to telnet into R1 without any issues from my PC thus eliminating the need for a console cable AND I can still access the internet at the same time. From R1 I'm able to ping all the switches in the LAN.
Here's the problem: I can't ping the switches from my PC. I just don't understand why that's possible. If I can ping R1 and R1 can ping the switches shouldn't R1 route to the LAN?
Someone please help me out with this. I'm stumped and I know I'm overlooking something simple. The object here is I want to eliminate the need for a console cable and be able to access the internet while simultaneous accessing my home lab.
