Cannot ping homelab

[Jasonmc010]

Hi,
Trying to get to grips with the cisco equipment hands on but I am struggling on this one.
I am trying to get my laptop (172.16.223.220) on my home network to ping the laptop on my homelab (192.168.30.3). The 1841 router has been allocated an IP of 172.16.224.212
I have internet access on the 1841 router which runs through my home router so there is a connection and I can ping everything on the 1841 router when connected to the console port, please see the diagram below of how it is connected. (ignore the colours)

Config Setting are below, I have tried using an IP route command but doesn't get me anywhere. 
I have searched online for an answer but anything I have found and tried still does not get it going.

Hi,

Your "home-router" needs to have a static route to 172.16.30.0/24 

ip route 172.16.30.0 255.255.255.0 172.16.224.212

The above command is how you do it on Cisco devices. So, not sure what vendor's device is your home-router.

Hi Reza,

I tried it this evening but no luck.
My router had decided to change the IP address of the cisco router to 172.16.224.199 but I have now made this static with the BT Hub router.

I have tried these below; but it still will not ping. I can ping from the homelab to my home network (Always been able too) but just not in reverse.
ip route 192.168.0.0 255.255.0.0 172.16.0.0
ip route 192.168.30.0 255.255.255.0 172.16.224.0
ip route 192.168.30.0 255.255.255.0 172.16.0.0

When i tried the suggestion, it came up with an 'Invalid next hop address (it's this router)' error.

Thank you for your help.

There are multiple levels of issues about this environment but I want to focus on one which is perhaps most important. You tell us "I am trying to get my laptop (172.16.223.220) on my home network to ping the laptop on my homelab (192.168.30.3)". Looking at the partial config provided I note that you have configured dynamic NAT for the 192.168.30.0 network. Dynamic nat like that would allow the PC in homely to ping your laptop (172.16.223.220) but does not allow your laptop to initiate the ping. To be able to ping the homelab PC you will need static nat. So you have an architectural issue in the network design (access from outside when dynamic nat is configured).
