Get muscle from home?

Question

Computer networks

In general, you need to reach through the Internet to the muscle server located behind the router and proxy, here is the scheme , muscle 0.3. I added such a rule on 1.1, now 0.2 is pinged and another 0.254 is also pinging from 192.168.1.1,
but packets from 1.1 to 0.3 do not reach. I add this rule on 192.168.0.2 , route add -net 192.168.0.0 netmask 255.255.255.0 gateway 192.168.0.254 eth0 I get an error: SIOCADDRT: Network is unreachable
