What mine did, I found by checking /proc/net/ip_conntrack on an
intermediate Linux router before the other openvpn peer: it was
changing the origin port. I do think it was a NAT bug on the D-Link
equipment.
D-Link support never escalated the matter beyond their first-level
support (if in fact there *is* a higher level?) so it wasn't worth my
time to pursue it. Just Say No to D-Link Routers, when making a
purchasing decision or recommendation.

Perhaps it's a NAT error there. In my case the remote Linux firewall
wasn't passing these packets to the peer, because the connection was
not seen as --state RELATED,ESTABLISHED (in Linux netfilter terms.)

You'll have to do a bit of detective work to find out what is happening
to your UDP packets.
