I'm guessing the ADSL router is a typical NAT router, and that your OpenBSD
router is *not* configured for NAT.  as a result, the ADSL router is seeing
outbound packets from 192.168.0.10, but doesn't know how to deliver the
inbound responses.  it knows that the 192.168.1/24 network is reachable via
one of its own LAN ports, but I'm guessing that it doesn't know how to reach
the 192.168.0/24 network.

you need a static route defined on the ADSL router telling it that for the
192.168.0/24 network, the next hop router is at 192.168.1.101.
