the netmasks you use  matter as well...
are both addresses on the route 146.232.144.XXX ?? One should use 147.
I assume netmasks are 255.255.255.0

you can leave it as it is but then set the routes properly.

On host1 
route add -net 146.232.147.0 netmask 255.255.255.0 gw 146.232.144.96
On host2 
route add -net 146.232.144.0 netmask 255.255.255.0 gw 146.232.147.107

So that both hosts know how to reach the other subnet via the router

And on host2
route add -net 192.168.0.0 netmask 255.255.255.0 gw 146.232.144.41

So that host2 knows that to reach lwip/tap it goes through host1
