If you run a script on the host to ping the router every minute or
so, does that fix things?
As Ken pointed out, your default gateway is not on the same IP
My guess: this works as long as the host initiates communication -
its routing table has the IP of the router, and it's on-link, so ARP
works - which is enough to get an entry in the ARP table of the
router and allow 2-way communication. The randomness is explained by
patterns of communication between your host and the router. I'm
guessing that, when its the router that initiates and it has no ARP
entry for the host, that it's sending the packets back to its default
route. (Traceroute from outside shows loops?).
If that's the case, you can fix the problem by adding a route (either
for your host or the additional IPs) on the router - presuming it
lets you configure routes targetting just an output interface..
Alternatively, put the router on the same IP subnet...
