You have mixed (sub)nets on each HN, 192.168.1.x and 192.168.2.x. How did you routed between subnets/hosts? Also, if you randomly mix subnets IPs, like 192.168.2.100 on HN1 and 192.168.2.102 on HN2 then routing tables will be a bit hard, you will need a route for every node instead having one route for every net. I don't know your needs, but splitting subnets in a different way will be easier to manage, for example 192.168.1.x for HNs, 192.168.2.x for VPx_HN1 and 192.168.3.x for VPx_HN2. This way you can route whole subnets to his HN- gateway, instead of routing individual VPs as you will have to do with the configuration you have now. You should read some docs about routing and net-splitting.
