A can ping B, B can ping C but A cant ping C. How do i connect A to C (ethernet)?

Now from my home computer I cannot ping this embedded device. How would I connect to it without changing the subnetwork it connects to? I can ping the embedded device from my work computer and I can ping the work computer from my home computer. So I am trying to connect to the embedded device from my home computer through my work computer. Port forwarding? how would I establish that on Ubuntu?

"The question is a little fuzzy (maybe be, first thing in the morning).

I would check your subnet masks, if you are on 255.255.255.0 then the .221, .1 and .0 machine are on completely separate networks.

As for the work and embedded machine, they are on the same network, but if they cannot communicate, my guess would be it is a routing conflict.

If this was me, I would disable the secondary interface on the work machine and make sure you put everything on the same network (255.255.255.0) and then use the ips in the same range (192.168.0.x).

If everything is on a subnet of 255.255.0.0 then they are on the same network already, so I would just disable the second interface on the work machine as this could be creating the conflict."
