Cascading routers - opening ports

Hello,

 

I've got Shaw's original Cisco router at 192.168.0.1

In Port Range forwarding I opened port 22 for SSH access and specified IP 192.168.0.15

I have another Cisco router at 192.168.1.1

 

For better firewall security, I connect Shaw's Cisco router to second router in a traditional way (the second router is plugged into a modem socket).

I then configure my second Cisco router to also open port 22 and this time IP is 192.168.1.105 (second router is where I connect my devices and I use Shaw's router as a modem).

 

192.168.0.15 is address of Shaw's router that I use to connect to second Cisco router.

192.168.1.105 is address of my laptop that I need to allow SSH access to it.

 

I don't understand why I cannot access via SSH with this configuration.  If I connect Shaw's router directly to my laptop at 192.168.0.15 It works.  But I want to have extra router for security and connect via second router that assigns my laptop 192.168.1.105.

 

How can I make SSH (port 22) connection go through Shaw's AND my second router?  Any ideas?

 

Thanks,

Victor.
