Deep Joy, it worked!!!
Changing upsd.conf to only contain "LISTEN 0.0.0.0 3493" solved the problem.
Syslog now looks like the attached Syslog Nut extract2 file.
Many thanks for your suggestion Charles.
Gene, I do use the firewall in my ISP supplied router, but I don't know how that stacks up against DDWRT. I do have a flashable router in the cupboard, so I might just give it a try.
Thanks all for your help.

I would add that the best place for the firewall is in your router, by
reflashing it with dd-wrt. In 2 decades of running it that way here, no
one has come thru it to gain nefarious access has managed to do so. By
putting your switch on the local side of your router, you have the run
of your local network, with no firewalls to have to putz with but
dd-wrt's sharp teeth are keeping the black hats out. Not to mention it
has no TLA back doors.
